International conference proceedings, A data model containing information of design and inspection data is important in inspection, maintenance, and asset management using information and communication technology. In this paper, we propose a three-dimensional (3D) bridge information model based on Industry Foundation Classes (IFC), which are a building information modeling standard, for the support of inspection, evaluation, and maintenance. Various data, such as text, photographs, point clouds, and measured polygon meshes, relating to the inspection, evaluation, and repair of a bridge are recorded in the 3D bridge model. A viewer system, which has the ability to visually present not only 3D geometric models but also a virtual-reality environment, is developed to show the model. This system also extracts information from past inspection reports written as documents. A data segmentation procedure is proposed for point clouds and measured polygon meshes. - A Digital Twin of Multi-Axis Machine Tool for Micro Process Planning

International conference proceedings,Abstract
Achieving high performance of machining production systems requires the use of multi-axis machine tools. In order to maximize the performance of multi-axis machine tools, micro process planning for creating machining data is important. Many researches on micro process planning mainly focused on 3-axis machining. As promising approaches among them, a micro process planning system was proposed that reuses actual machining cases and analyzes case data to derive the necessary rules. However, it is not always effective for multi-axis machining, because enough case data are not collected for micro process planning of a specific multi-axis machine tool. In this study, a digital twin of multi-axis machine tool in cyberspace is proposed to collect real and virtual machining case data for micro process planning. - Associating 2D Sketch Information with 3D CAD Models for VR/AR Viewing During Bridge Maintenance Process

English, Scientific journal, Virtual reality (VR), augmented reality (AR), and mixed reality technologies are utilized at various stages of product lifecycle. For products with long lifecycles such as bridges and dams, the maintenance and inspection stages are very important to keep the product safe and well-functioning. One of the advantages of VR/AR is the ability to add important information such as past inspection data. Past inspection information is summarized in a document consisting of the 2D sketches of bridge degradation drawings. However, this degradation sketch is in 2D, and it has no correspondence with the 3D world. In this study, we propose a method to associate important information of 2D sketches with a 3D industry foundation classes (IFC) model, which is a standardized computer aided design model. To display a VR image of a bridge during the inspection process, the proposed method is applied to the 3D IFC model of the bridge and 2D degradation sketch of the inspection report. - Error Estimation of Machined Surfaces in Multi-Axis Machining with Machine Tool Errors Including Tool Self-Intersecting Motion Based on High-Accuracy Tool Swept Volumes

English, Scientific journal, A novel method is proposed for estimating the machining errors on machined surfaces caused by errors of multi-axis machine tools, such as geometric errors, based on a new generating method of tool swept volumes. In the proposed tool swept volume generation method, the boundary surfaces of the tool swept volumes are derived as triangular mesh models satisfying the required approximation accuracy based on the tangency condition. Using the proposed method, tool swept volumes can be derived for various tool paths including the tool self-intersecting motion. A tool path evaluation method based on the error vectors with respect to the start position of a specific tool path is also proposed. In the proposed evaluation method, error vectors on machined surfaces are derived by comparing the points on the nominal tool swept volumes (ex-cluding the machine tool errors) with the triangles on the error tool swept volumes (including the machine tool errors). - Bridge Information Modeling based on IFC for supporting maintenance management of existing bridges

Japanese, <p>House-collapsing simulation using a physics engine is an effective method for acquiring structural data regarding collapsed houses with the aim of understanding the properties of destroyed or disordered structures for designing and operating rescue-robots. However, the simulation needs a lot of time since a house model consists of a large number of rigid bodies and joints. In order to find an appropriate configuration of computer hardware and software for accelerating house-collapsing simulations, this study evaluates the performances of four major physics engines, namely Open Dynamics Engine, Bullet Physics Library, PhysX 2.8.1 and PhysX 3.4, by comparing the processing time about two sample structures including only rigid bodies or rigid bodies constrained by joints. Results of the experiments show that the use of multi-core CPU and GPU, especially high-speed GPU, on PhysX 3.4 has the best performance since it can process a large number of rigid bodies and joints in parallel. Based on the results, an existing simulation system has been improved and the collapsing process of one-house, which consists of about 7,500 rigid bodies and 15,000 joints, can be simulated in real-time using multi-core CPU and GPU. Moreover, this study estimates the size of GPU memory which is required for simulating the large-scale field on PhysX 3.4 to enlarge the scale of simulation. Consequently, the collapsing process of thirty-houses which includes interactions between collapsed houses can be simulated.</p> - Development of a bridge inspection support system using two-wheeled multicopter and 3D modeling technology

English, Scientific journal, Recently, many countries have faced serious problems associated with aging civil infra structures such as bridges, tunnels, dams, highways and so on. Aging infrastructures are increasing year by year and suitable maintenance actions are necessary to maintain their safety and serviceability. In fact, infrastructure deterioration has caused serious problems in the past. In order to prevent accidents with civil infrastructures, supervisors must spend a lot of money to maintain the safe conditions of infrastructures. Therefore, new technologies are required to reduce maintenance costs. In 2014 the Japanese government started the Cross-Ministerial Strategic Innovation Promotion Program (SIP), and technologies for infrastructure maintenance have been studied in the SIP project [1]. Fujitsu Limited, Hokkaido University, The University of Tokyo, Nagoya Institute of Technology and Docon Co. Limited have been engaged in the SIP project to develop a bridge inspection support system using information technology and robotic technology. Our system is divided into the following two main parts: bridge inspection support robots using a two-wheeled multicopter, and an inspection data management system utilizing 3D modeling technology. In this paper, we report the bridge inspection support system developed in our SIP project. - Tool swept volume generation method using tool swept profile curves for multi-axis machining with errors (5th report)

Japanese,Rescue robot simulation is an effective method for evaluating the performance of rescue robot in various rubble fields. However, simulating a rescue robot in a large rubble field such as a collapsed house needs a lot of time, since it needs to process a large number of rigid bodies and joints. This study accelerates the rescue robot simulation by using multi-core CPU and GPU on a physics engine. To consider the effect of GPU about rescue robot simulation, this study measures the processing time of two situations, including only rescue robot or a rescue robot and rubbles, on two computers equipped with different GPU. Result of the experiments show that the use of GPU, especially high-speed GPU, is effective for a situation which includes a rescue robot and rubbles. Based on the results, this study simulates a rescue robot in a collapsed house in real-time using GPU.

Japanese, Error characteristics of multi-axis machine tools such as geometric errors cause machined errors on machined surfaces of machined parts. To estimate the machined errors on machined parts, shapes of machined parts with machined errors should be derived in computer simulation. By representing shapes of machined parts as difference set between a workpiece and tool swept volumes, the machined errors on machined surfaces can be estimated. A tool swept volume is composed of tool swept areas on tool surfaces that form surfaces of the tool swept volume. Tool swept areas on tool surfaces change its shape depending on tool motion. In order to derive tool swept volumes without any restriction on tool motion, all shape types of tool swept areas should be classified as tool swept types for general tools in multi-axis machining. Hence, in our previous study, tool swept types of cylindrical surface (side surface of a flat endmill), tapered surface (side surface of a taper endmill) and planar surface (bottom surface of an endmill) were classified. In this paper, tool swept types of torus that represents a corner radius of a radius endmill are classified into 8 tool swept types. - A Study of Machined Surface Group Generation based on Tool Attitude Evaluation

Japanese, Cutting speeds on the cutting edge of Ball-nose end mill vary from the bottom to the top of the cutting edge, thus the portion of the cutting edge that has a suitable cutting speed should be used in the finish milling process. This paper describes a procedure of generation of surface element groups that can be machined by the high performance portion of cutting edge in the finish milling process. For this purpose, performance values of cutting points on the cutting edge are proposed. The tool attitude to the surface element is evaluated by the ratio of the area machined by the high performance portion of cutting edge based on proposed performance values. The tool attitude having maximum area of the surface elements that can be machined with the high performance is derived, and a set of surface elements that can be machined by the high performance portion of cutting edge for the tool attitude is obtained as the surface element groups. - Representation of Cutting Edge Motion Trajectory in Ball-End Milling Based on a Four-Dimensional Mesh Modeling (2nd Report)

English, International conference proceedings, House-collapsing simulation is an effective method for acquiring structural data regarding collapsed houses with the aim of understanding the properties of destroyed or disordered structures for designing and operating urban search and rescue (USAR) robots. The purpose of this study is to find an appropriate configuration of computer hardware and software that can accelerate house-collapsing simulations. This study compares the performances of three major physics engines, namely PhysX, Bullet Physics Library, and Open Dynamics Engine (ODE), on four computers equipped with different CPU and GPU configurations with respect to a sample structure, including a large number of rigid bodies combined with joint elements. Results of the experiments show that multi-threaded processing on PhysX has the best performance among the engines tested, and the use of multiple CPU and GPU configurations does not contribute to the acceleration of collapsing simulations for joint-connected rigid body structures in any of the evaluated versions of the physics engines. Based on the results, an existing simulation system for collapsing processes has been improved and can successfully speed up the process of collapsing simulations to approximately four times as fast as our previous system. To achieve greater speeds and larger-scale simulations, up-to-date physics engine technologies must be continuously examined and adopted for practical use in house-collapsing simulations. - Bridge Information Model Based on IFC Standards and Web Content Providing System for Supporting an Inspection Process

English, International conference proceedings, In order to satisfy the requirements of the machined part under effects of machine tool error characteristics such as geometric errors, the errors on the machined surfaces caused by the error characteristics should be estimated and taken into account in the process planning before actual machining. To estimate the amount of machining errors on the machined surfaces, the shape of the machined part should be derived. In computer simulation, a shape of a machined part is derived as a difference set between a workpiece and tool swept volumes. Hence, in this study, the generating method for tool swept volumes under effects of machine tool error characteristics has been proposed based on the tangency condition. In the previously proposed method, it was assumed that there was only one swept state, that is, two curves on a tool that generate tool swept volumes. However, there are other swept states of a tool, for example, two lines and a circle that generate tool swept volumes, and tool swept volumes of such states cannot be derived by the previously proposed method. Hence, in this paper, swept states of the generalized tool are classified as tool swept types based on the analysis of the tangency condition. Furthermore, the generating method of tool swept volumes for each tool swept type is proposed. - A comprehensive approach for managing feasible solutions in production planning by an interacting network of Zero-Suppressed Binary Decision Diagrams

English, Scientific journal, Product Lifecycle Management (PLM) ranges from design concepts of products to disposal. In this paper, we focus on the production planning phase in PLM, which is related to process planning and production scheduling and so on. In this study, key decisions for the creation of production plans are defined as production-planning attributes. Production-planning attributes correlate complexly in production-planning problems. Traditionally, the production-planning problem splits sub-problems based on experiences, because of the complexity. In addition, the orders in which to solve each sub-problem are determined by priorities between sub-problems. However, such approaches make solution space over-restricted and make it difficult to find a better solution. We have proposed a representation of combinations of alternatives in production-planning attributes by using Zero-Suppressed Binary Decision Diagrams. The ZDD represents only feasible combinations of alternatives that satisfy constraints in the production planning. Moreover, we have developed a solution search method that solves production-planning problems with ZDDs. In this paper, we propose an approach for managing solution candidates by ZDDs׳ network for addressing larger production-planning problems. The network can be created by linkages of ZDDs that express constraints in individual sub-problems and between sub-problems. The benefit of this approach is that it represents solution space, satisfying whole constraints in the production planning. This case study shows that the validity of the proposed approach. - A Study on Evaluating the Traversing Performance of Rescue Robots Moving over Rubble Fields with Various Features

Japanese, Dynamic changes as machine breakdowns make current production plan infeasible and inaccurate. The influence of dynamic changes spread to whole production planning that consists of several domains such as process planning, production scheduling and so on. In this study, solution space in the production planning is defined as comprehensive. We have applied Zero-Suppressed Binary Decision Diagrams (ZDDs) for the representation of solution candidates that satisfy constraints between such domains so for. In dynamic production planning problems, manufacturing achievements and dynamic changes may make solution space change. In this paper, we define such events as constraints for ZDDs and propose an approach to update the ZDD to deal with the events. Moreover,we propose a genetic algorithm (GA) to find solutions in the ZDD. Experimental results demonstrate that the proposed approach to address such event with ZDDs and the GA are effriciently used to solve the dynamic production planning problem. - Tool swept volume generation for multi-axis machining with geometric errors based on the tangency condition

English, Scientific journal, In the field of design and manufacturing, there are many problems with managing dynamic states of three-dimensional (3D) objects. In order to solve these problems, the four-dimensional (4D) mesh model and its modeling system have been proposed. The 4D mesh model is defined as a 4D object model that is bounded by tetrahedral cells, and can represent spatio-temporal changes of a 3D object continuously. The 4D mesh model helps to solve dynamic problems of 3D models as geometric problems. However, the construction of the 4D mesh model is limited on the time-series 3D voxel data based method. This method is memory-hogging and requires much computing time. In this research, we propose a new method of constructing the 4D mesh model that derives from the 3D mesh model with continuous rigid body movement. This method is realized by making a swept shape of a 3D mesh model in the fourth dimension and its tetrahe-dralization. Here, the rigid body movement is a screwed movement, which is a combination of translational and rotational movement. - Using a Four-Dimensional Mesh Model to Represent a Tool Motion Trajectory in Five-Axis Machining.

English, Scientific journal, Annotations on Geometric Dimensioning and Tolerancing (GD&
T), surface roughness, etc. are needed for machining or measuring. However, these annotations are not used for the digital format in the product development process, nor is there any clear, explicit relationship between annotation, machining information, and measuring results. In this research, an integrated information model for design, machining, and measuring based on annotated features is proposed. A model for surface texture is also proposed because surface texture parameters are closely related to machining process parameters. A modeling system for the proposed integrated model is also implemented. - Comprehensive representation of feasible combinations of alternatives for dynamic production planning using Zero-Suppressed Binary Decision Diagram

English, Scientific journal, The goal of the production-planning problem is to find the optimal solution from combinations that satisfy constraints. Traditionally, production-planning problems have been treated separately, due to the problem size and complex constraints, whereas the constraints in production planning spread to the entirety of production planning. For example, when the dynamic changes as machine breakdowns and new machine addition occur, a production plan should be modified with new constraints caused by these dynamic changes. Therefore, it is required to represent a set of solution candidates that satisfy constraints in production planning. Zero-Suppressed Binary Decision Diagram (ZDD) is a directed graph representation of Boolean function and can efficiently represent a set of combinations. This paper describes the validity of application of the ZDD to production planning to represent a set of solution candidates. Experimental results applied to a sample-planning problem demonstrate that the ZDD is efficiently used for production planning and for dealing with dynamic changes. - Direct Construction of Four-Dimensional Mesh Model from Three-Dimensional Object with Continuous Rigid Body Movement,

Japanese, This study proposes an automatically customizable micro process planning system that reflects the change of properties of an actual machine tool to generate optimal machining information. The system consists of an updatable machining database and a database-oriented micro process planning algorithm. A machining database is updated based on analyzing NC data that are adaptively generated for an actual machine tool by skilled process planners. From the updated machining database, a database-oriented micro process planning algorithm is generated by a decision tree and a regression tree. Machining strategy and cutting tools are determined using IF-THEN rules that are generated from the database by the decision tree method. Cutting conditions are determined from a feasible regression equation. Regression equations and selection rules of these equations are generated from the database by the regression tree method. An example of micro process planning using the generated algorithm is also shown. <br> - CUSTOMIZATION OF A MICRO PROCESS PLANNING SYSTEM FOR AN ACTUAL MACHINE TOOL BASED ON UPDATING A MACHINING DATABASE AND GENERATING A DATABASE ORIENTED PLANNING ALGORITHM

Japanese, Scientific journal, To automatically generate and update a machining database for feature based process/operation planning, a generating and updating method of a machining database based on Numerical Control (NC) data analysis is proposed. As the content of the database, the ISO 14649 machining information which consists of machining feature, machining operation, machining strategy, cutting tool and cutting conditions is derived from NC data, a cutting tool model and a rawpiece model. To derive the machining information for a machining feature, the tool paths are split according to their geometrical characteristics of the tool path, and a machining feature is derived from the machining process model which is generated from a split tool path, a cutting tool model and a rawpiece model. A machining operation for a machining feature is identified as roughing or finishing operation based on the geometrical relationship between the machining process models. A machining strategy is extracted from a split tool path based on tool motion pattern. As the cutting conditions, spindle speed and feed rate are derived from S and F code of NC data. The example of generating ISO 14649 machining information from NC data using the proposed analysis method is shown. - Framework of dynamic production planning for adaptive manufacturing execution (3rd report):Study of search algorithm to find solution from a set of feasible combinations by ZDD

The first part of the paper discusses what to be studied about gareki with respect to search and rescue activities. To share knowledge about gareki, the concept of digital gareki archives is explained and four approaches for gareki data acquisition are discussed. As a prototype of digital gareki archives, a computer software system named Virtual Gareki Field (VGF) which generates digital gareki data based on collapsing process simulation has been developed and models and tools related to VGF are explained. - 3268 Computer aided operation planning for an actual machine tool based on updatable machining database and database oriented planning algorithm

English, Scientific journal, In the communication and sharing of product data, if the difference of the required data quality and the data quality actually incorporated into data is significant, it causes various problems. It is often the case that a creator of low quality data does not realize it unless it is harmful for his job. In most cases, low quality data passed to subsequent processes, such as manufacturing process, cause problems since these are not appropriate from the machining precision point of view or the detailed shape modeling point of view. In these cases, rework or repair of data is necessitated before commencing the target process, which results in significant economy loss and delay of product development. Today's product model data are dumb data because design intents and data quality incorporated are not explicitly represented. Receiving systems cannot know whether the data passed possess sufficient quality for the target job or not. Another problem is that engineers in later processes, such as the manufacturing process, cannot issue data quality related request beforehand in a commonly agreed manner. The problems mentioned above are caused by the lack of a commonly agreed representation of product data quality (PDQ) information. Our proposed solution is designed to enable the communication and sharing of data quality information. This paper reports the development of a PDQ standard (ISO 10303-59), which is a resource part of ISO 10303 Standard for the Exchange of Product Model Data (STEP) (2008, "ISO 10303-59, Industrial Automation Systems and Integration. Product Data Representation and Exchange. Part 59 Integrated Generic Resource: Quality of Product Shape Data," International Standard Organization, Geneva). The objective of ISO 10303-59 is to establish a PDQ model and to enable the use of PDQ data independently or in combination with product data. The developed PDQ information model represents concepts such as data quality criteria, measurement requirements, and measured results. Based on the PDQ model, the PDQ for shape data model, which is a specialization of the PDQ model to 3D shape data quality, is also developed.[DOI: 10.1115/1.3402615] - CURRENT SITUATION AND PROBLEMS FOR REPRESENTATION OF TOLERANCE AND SURFACE TEXTURE IN 3D CAD MODEL

English, In a machining system using computer numerical control (CNC) machine tools, detailed models of machining information are necessary to simulate detailed machining and to control the complex motion of machine tools. However, existing machining information models lack the necessary information and are described in their own formats. Consequently, many models which include the same information exist. Moreover various simulations for a virtual machining system and adaptive control for a real machining system are inacculate. To solve these problems, a digital machining information (DMI) model to support a real-virtual machining system is proposed in this study. - Analysis of NC Data Based On CNC Data Model For Retaining Machining Information

English, International conference proceedings, Inappropriate data problems due to mismatching of product data quality are always possible in data communication and sharing. In this problem, the data is evaluated as valid within the original system and its initial usage, but problem brake out during the reuse phase of the same data. This delayed problem requires data repair or rework operation in the subsequent manufacturing process and results in significant economic loss.
As cause, current product data is a dumb model and its quality is not guaranteed. The receiver system cannot identify whether the data has sufficient quality for reuse or not. Furthermore, manufacture's advance notice of their request for data quality is impossible.
This paper proposes an establishment of PDQ (product data quality) information for communication of data quality that can be used independently or in combination with product data. The PDQ information model presents qualitative measurements according to given criteria, and the measured portion of product data. Based on PDQ model, a PDQ-S (PDQ for shape data) model has been developed. For PDQ-S, industrial guidelines about shape data communication are systematically categorized as the baseline of guarantee.
The PDQ model is intended to be independent and neutral from calculation algorithm of measurement. As the method of development, STEP (ISO 10303: Standard for the exchange of product model data) architecture was adopted and the PDQ model was developed as a resource of STEP standards. We show an example about combination of shape data and concerned quality guarantying data. - Study of Process Planning based on Feature Dependency of Manufacturing Features (1st Report) : The representation of Feature Dependency and Basic Concept of Process Planning System

Japanese, Computer aided process planning has been expected to accomplish integration between design and its downstream, and has a role of a bridge between CAD and CAM applications. Since manufacturing feature recognized from CAD database is applied to communicate information in computer aided process planning, it becomes a key issue how to manage manufacturing features to achieve optimum process planning with minimum human intervention. For this purpose, an idea of a feature dependency of manufacturing feature based on a base plane is proposed. The feature dependency is a collection of manufacturing features based on the base plane in a hierarchy relationship. The base plane is a planar face which corresponds to a machine tool axis direction. Using this base plane and its feature dependency, each feature can be assigned to each specified process immediately and correctly, and all the successive process planning work is completed effectively. The systematic methodology for process planning, including unrecognized features, using feature dependency based on a base plane is presented, and the possibility of implementation applying this approach is verified by developed prototype CAPP system. - Development of a Digital Machining Information Model to Support a Real-Virtual Machining System

Japanese, Manufacturing feature is key information to achieve data sharing between CAD and the following manufacturing process. It is well known that the data of the feature is first generated by feature recognition from CAD geometry, and then applied to the process planning. Our study has examined the process planning based on Feature Dependency and have demonstrated the way to create and implement the feature dependency. First report demonstrates that representing the feature dependency which contains feature hierarchy when applying the data to the process planning leads the following process to be more efficient and accurate. In the second report, features including division and/or unification, i.e. dynamic feature, are discussed. Previous two papers focus on the features which have explicit relationship with geometry, i.e. explicit feature, are discussed. In this paper, feature dependency that has no explicit relationship with geometry, i.e. implicit feature, such as a thread, surface finish, removal thickness and finishing allowance are also discussed and the method of integrating explicit features and implicit features into one feature dependency is introduced. - Study of Process Planning based on Feature Dependency of Manufacturing Features(2nd Report) : Improvement for Feature recognition and Creation of Feature Dependency with Manufacturing View

Journal of the Japan Society of Precision Engineering, 73, 5, 588, 592, The Japan Society for Precision Engineering, 2007
Japanese, Since a manufacturing feature, in computer aided process planning (CAPP), is the medium of information communication in the data sharing between design and manufacturing, i.e. CAD and CAM, it has an important role to complete optimum process planning in its correct capture and communication capability. For the purpose of improving this communication, an approach of using a feature dependency of manufacturing feature based on a base plane was proposed and verified for smooth integration between CAD, CAPP and CAM in the previous paper. According to successive trial and usage by real machining parts in some industries, it becomes clear that a certain feature such as a chamfer element causes effects of annoyance for other feature recognition, and multiple feature definition for a single feature is required under interactions by the others. To solve these requirements for applying more sophisticated parts, filtering method for undesired features to complete correct feature recognition and multiple feature definitions for features in interactions are proposed in this paper. Finally the representation schema of feature dependency including these results is proposed, and the approach is verified by a developed prototype SCAPP system. - Sculpture Surface Machining by Automatically Indexing Tilted Tool Axis on 5-axis Machine Tools(3rd report) : Evaluation of tool attitude by analysis of cutting force on tilted tool axis ball end milling

Japanese, Nowadays most of die and mold machining are manufactured by three dimensional controlled machining using ball end mill. Using this manufacturing method, we can obtain complex shapes by point contact machining between cutting tool and workpiece. To shorten set-up time and machining time, we have proposed 3+2 axis controlled machining method which the mold and dies are machined by indexing tilted tool axis on 5-axis machining center. In the proposed machining process, high speed machining is executed on each tilted tool axis. In this machining process, the list of indexing angle should be determined automatically, because the shape of the die and mold is very complex to determine the angle by an operator. Therefore, the main objective of this research is automatic determination method of the list of indexing angle for machining the die and mold. We have proposed, in the first and second reports, the calculation method of optimum indexing angle candidates for required machining surfaces using normal vectors of the surfaces and effective cutting edge shapes. And we have shown the procedure of deriving of optimum indexing angle and machinable area based on inverse offset method with state flag. However, we need the effective tilting angle range which we get the stable machining condition in tilted tool axis ball end milling. For this reason, in this research, we propose the machining experiment method using dynamic force dynamometer on 5-axis machining center to analyze the machining properties using tilted tool axis ball end cutting tool. And, we show the machining evaluation diagram from which the results of machining experiments property by tilted tool axis ball end cutting tool. - A proposal of a complex manufacturing space and consideration of its technical issues for its implementation

Movement toward concurrent and collaborative e-engineering drives the need for assuring the quality of the communicated product model data. In this paper, a quality diagnosis method of the shape data of a neutral file based on a product model including curved surface described in formal language is proposed. The proposed method is based on the standard for the exchange of product data (STEP) technology using EXPRESS-X, which is the mapping language between STEP model data. In order to help create the data quality diagnostics criteria for geometric errors easily, the classification of the quality criteria based on their geometric algorithms is also proposed. The certification data model of the product data is proposed to avoid a tedious checking procedure in the receiver system. Some of the quality criteria, which were published by the Strategic Automotive Product Data Standards Industry Group (SASIG), are rewritten in formal language and applied to the data sets including the error set provided by the Japan Autornotive Manufacturers Association (JAMA) to demonstrate the effectiveness of the proposed diagnostics method. The approach based on the formal language is extensible for any phase of the product development process by rewriting the criteria. Not all SASIG criteria have actually been implemented. Future work is to rewrite all SASIG-PDQ criteria into EXPRESS-X schemas. (c) 2006 Elsevier B.V. All rights reserved. - Machining Feature-Driven 5-Axis CNC Machine Tools

English, International conference proceedings, In. order to realize the articulate link between design and manufacturing and a traceable manufacturing system, it is necessary to represent the semantics of information independently of any implementations. Moreover, the quality of data that represent information should be ensured during the product life cycle. A significant amount of research for machining process planning and machining feature extraction has been carried out to help realize an integrated CAD/CAPP/CAM system. However, all data are not used throughout product development processes. The Standard for the Exchange of Product model data (STEP) has also emerged as a viable method for product model data exchange among design activities. However, a consistent application for integrating design, process planning and machining for mechanical components based on STEP/AP set has not completely been developed thus far. In this research, the Digital Semantic Model that fulfills the above requirements is proposed. In this paper, modeling and implementation of Digital Semantic Model for 5-axis machining is reported. - Analysis of ISO 6983 NC data based on ISO 14649 CNC data model

English, International conference proceedings, A new method for non-contact shape measurement of a specular surface like metallic surface, is proposed. The principle of the proposed method is the simultaneous measurement of 3D coordinates and normal vector on a specular surface using double laser spot images. Position and direction of the reflected beam are detected by the projected spot image on a l-axis movable screen. Then, the position and the normal vector of the reflection point on the surface are determined based on the law of ray reflection. Both position and normal vector are measured simultaneously. The system, based on the proposed method, contains only standard devices: a laser, a CCD camera and a screen. An experimental setup has been created to check the validity of the proposed method. To test the apparatus we measured some primitive shapes. The experimental results are shown and accuracy in addition to the properties of the proposed method, are evaluated. - Sculpture Surface Machining by Automatically Indexing Tilted Tool Axis on 5-axis Machine Tools (2^

Japanese, Nowadays most of die and mold makers use High Speed Cutting or Machining in cavity and core manufacturing. However, finishing processes for injection molding molds and die casting dies are done by EDM because these applications have many thin and deep cavities to be machined. Otherwise, the long solid carbide milling cutters are necessary for machining these molds and dies. To save set-up time and avoid using the long solid carbide milling cutters, we have proposed 3+2-axis high speed machining on a 5-axis machining center. The 3+2-axis machining is the sequence of machining by indexing titled tool axis on 5-axis machining center. In the 3+2-axis machining process, the sequence of indexing angles must be determined automatically, because the shape of the die and mold is very complex to determine the indexing angles by an operator. Therefore, the main objective of this research is to propose an automatic determination method of the sequence of indexing angles for machining the die and mold. We have proposed, in the first report, the calculation method of optimum indexing angle candidates for given required machining surfaces using normal vectors of the surface and effective cutting edge shape, and the machinable area derivation method of calculated indexing angle based on inverse offset method with state flag. In this report, we extend the proposed calculation method to determine the sequence of indexing angles for a complex machining shape. Firstly, in order to represent machinable information of facet, a new facet data structure is proposed. Secondary, the precise representation of machinable area on the offset surface is proposed. Finally we illustrate an example to demonstrate the effectiveness of the proposed method. - Data transformation from ISO6983 data to ISO14649 to obtain machining knowledge using EXPRESS-X

English, Technical information, such as machining features, type of machining operations and machining conditions, should be represented explicitly and integrated into one data structure with some relation between the information in order to manage, modify, and verify NC data and avoid human error. However, traditional NC data (ISO 6983) contains such kind of technical information implicitly. In this research, technical information is extracted from NC code, and the extracted technical information is transformed into a next-generation CNC control language (ISO14649) which contains the technical information, and the ISO 14649 data are stored in XML. - Step based product model data quality diagnosis for collaborative e-engineering

English, International conference proceedings, The movement toward concurrent and collaborative e-engineering drives the need for assuring the communicated product model data quality. A classification for model data quality errors has been developed by the Japan Automotive Manufacturers Association (JAMA), the Japan Auto Parts Industries Association (JAPIA), and the Strategic Automotive Product Data Standards Industry Group (SASIG). However, these criteria are described in natural language (Japanese and English), and a certain amount of ambiguity exists in the measurement methods of the product data quality. To solve this problem, the criteria should be described in formal language or programming language. In this paper, we propose a diagnosis method of product model data quality based on STEP technology using EXPRESS-X which is the mapping language between STEP model data. The certification data is described in XML and linked to the original product data. We also propose the certification data model of the product data. We show some examples to demonstrate the effectiveness of the proposed diagnostics method. - Software System for Sculpture Surface Machining Based on 3+2 Axis Control High Speed Machining on a 5-axis Machining Center

Japanese, The technical information, such as Machining feature, type of machining operation and machining condition, is necessary for operator to use NC code in the shop floor. However, NC code has no relation each other in explicit form. Then, it is difficult to manage, modify, and verify NC data. Therefore this is the cause of the human error. In this research, the technical information is extracted from NC code, and the technical information is transformed into a next-generation CNC control language(ISO 14649) which contains the technical information.

Today nearly all die and mold makers use High Speed Cutting or Machining in cavity and core manufacturing. However, finishing processes for injection molding molds and die casting dies are done by EDM because these applications have many thin and deep cavities to be machined. Otherwise, the long solid carbide milling cutters are necessary for machining these molds and dies. To save set-up time and machining time, it is desire to machine by High Speed Cutting or Machining in such machining portions. To solve this problem, mold and die machining by indexing tilted tool axis on 5-axis machining center is proposed in this paper. In the proposed machining process, High Speed Machining is executed on each tilted tool axis. In this machining process, the list of indexing angle should be determined automatically, because the shape of the die and mold is very complex to determine the angle by an operator. Therefore, the main objective of this research is automatic determination method of the list of indexing angle for machining the die and mold. Firstly, we propose the calculation method of optimum indexing angle for required machining surfaces using normal vectors of the surfaces and cutting edge shapes similar to the Gaussian Sphere method. Secondary, we propose the machinable area evaluation method of calculated indexing angle based on inverse offset method with state flag. Finally, we illustrate an example to demonstrate the effectiveness of the proposed methods. - High Efficiency Sculpture Surface Machining by Automatically Indexing Tilted Tool Axis on 5-axis Machining Center in Mold and Die Machining

Japanese, This paper presents a new method for adapting the existing manufacturing system for a requirement change, such as the change of a required motion task, by modifying its kinematic structure from the viewpoint of the degrees of freedom of the end effecter of the mechanism. In a previous report, the authors formulated the kinematic structure and motion task using Lie algebra. In this report, using these representations and their inclusion relations, the authors propose a method for evaluating the reusability of a kinematic structure for a newly specified motion task, and then propose a method for reconfiguring the mechanism in Lie algebra according to the result of the reusability evaluation. Finally, in order to evaluate the usefulness of the proposed method, it is applied to a kinematic design example of a mechanism. - 420 Removal Volume Modeling for Process Planning Based on Form-Shaping Function

English, In machining process planning, delta volume, which is derived by subtracting required shapes from raw material, is decomposed into some elements that are assigned to specific machining features and related to the specific machining processes. Therefore, the removed material of the raw stock, the removal volume, is the key element for deriving the previous shape of raw stock and determining the machining sequence in the machining process planning. It is thought that the removal volume contains information about the shape of the removed material and the machining process. This paper proposes a removal volume model which has the shape of the removed material and the machining process for a machining process plan based on a working tool model derived from the Form-Shaping Function mathematical model of machining operation. - 420 Removal Volume Modeling for Process Planning Based on Form-Shaping Function

Japanese, This paper presents a new method for kinematic synthesis of mechanisms from motion task specifications in a conceptual design. The motion task is classified into continuous path or positioning task. The former is the task that moves a mechanical part along a required path, and the latter is the task that puts the part in a particular position or orientation. The authors formulate them mathematically using Lie algebra and propose a method for generating an initial solution of the mechanism that can perform the specified motion tasks. From this solution, the constraint reduction procedure can reduce the redundant constraints such as joints to derive a minimum equivalent mechanism. By applying this mechanism to the synthesis procedure proposed in our previous report, a number of equivalent mechanisms can be derived. Finally, in order to evaluate the usefulness of the proposed method, it is applied to an example of kinematic design of mechanism. - A Study of Process Planning based on Machining Process Modeling (2nd Report) : Geometric model of Operating Step and Working Tool for Milling Operation

Japanese, This paper deals with geometric aspect of machined shapes and a machining process, which correspond directly to the machining process model. In order to make robust assignment rules of machining process, the working tool and operating step were introduced in the previous report. Moreover, to capture the essential information, the dimensions of operating step and working tool are also proposed as the parametric representation of them. However, it is necessary to consider the geometric representation of operating step and working tool, because the geometric information is used in feature extraction process from product model, and essential information of process plan are a tool shape and a tool path. In this paper, geometric model of working tool and operating step in three axis milling machine is discussed based on form shaping function. 16 classes of working tool are also proposed for the process planning. - EXPRESS/XML Based Cutting Tool Information Model and Tool Life Cycle Support

This paper deals with the methodology to construct a cutting tool database and to manage cutting tool information for distributed cutting tool management system using internet. In the past study, by introducing STEP technology and using EXPRESS and EXPRESS-G, we designed an information model of cutting tools, thereby representing models of such basic tool database as parts structure, assembly, nominal size and real size. We proposed an EXPRESS early binding XML for capturing the nature of tool data model, and for generating the serialization format of an EXPRESS data model, and evaluating its usefulness. The conversion of translators to any database systems is done according to mapping model represented by EXPRESS-X using to describe the conditions for conversion. - Modeling of machining process planning based on inverse form-shaping function

English, International conference proceedings, This paper deals with a model of process planning based on an inverse form-shaping function. A machining process model, defined as the form-shaping function, has been proposed and analyzed by many researchers. If the process planning is considered as an inverse process of the machining process, the process planning model can be easily established by inverting the form-shaping function. To accomplish this, the parametric form-shaping function as the machining process model and inverse form-shaping function as machining process planning model are proposed. - Constraint reduction based on a Lie algebra for kinematic analysis of assembly

Japanese, This paper deals with process planning system based on machining process model. So far, the taxonomy of machining features, for example, hole, pocket, slot, etc. are shape based classsifications and it is difficult to assign the machining process information without competition of assignment rule. To solve this problem, the machining process modeling is needed for mapping between machined shape element and machining process. However, only tool behaviors are derived from giving the tool and the cutting motion to the machine tool. Therefore, the behavior model of cutting tool, working tool, to connect the machining operation and machined shapes are introduced. The working tool consists of the swept macro tool, the envelope of the swept macro tool, and the working edge. The feature model of the machining process, operating step, is also proposed from the viewpoint of a macro cutting tool, controled table motion, and enveloping constraints. To capture the essential information, the dimension of operating step and working tool are also proposed as the parameric representation of them. - Constraint representation and reduction based on Lie algebra in assembly model

The purpose of this study was the improvement of productivity of optical products like as SLR lens. Therefor this study had proposed the "Virtual PT System" concept as a method to realize the suitable tolerancing for optical products and realized this system. According to this concept, this report proposes the new product model of SLR lens to evaluate the optical performance in real product condition. The proposed SLR lens model can represent uniquely the position and orientation of all parts as relationship of coordinate transformation. And also, this model can represent the mechanical structure with both manufacturing error and assembling error by same manner. Using this SLR lens model, the designer can easily obtain the both lens surfaces decentering amount and optical performance on real product condition precisely. - 5-Axis Control Machining by Shape Measurement on Machine Tool

English, Scientific journal, In the industrial use of stereolithography, precision is always a problem. The basic phenomenon of solidification shrinkage has not been sufficiently investigated. This study aims at clarifying the initial linear shrinkage of cured resin in a minute volume. Experimental equipment has been developed which measures the time history of the single strand in situ in a stereo I ithography machine. An analysis model of the time history of a minute volume linear shrinkage was shown using the measured shrinkage of a cured line segment. The relation between the time history of the linear shrinkage and temperature was measured and the shrinkage in the minute volume after irradiation was found to result due to temperature variation. Deformation and linear shrinkage were measured with two scanning orders to control the thermal distribution in layer forming. The effects of thermal distribution were also observed in one layer forming. - A Development of Statistical Tolerancing System for Optical Products

Japanese, Determination of tolerances is very important during product manufacturing in order to maintain low cost while achieving a consistent level of product performance. However, with optical products, precise, quantitative prediction of tolerance sensitivities, optical performance, and productivity in a mass production environment have been very difficult in the design stage The purpose of this study was the development of a statistical tolerancing system for optical products based on computer simulations (called Virtual PT System). The development of the mass-production simulation system was already reported in the first paper. As the second step of this study; the development of the complex sensitivity analysis system, which is based on the stepwise multiple regression method are reported in this paper. This system analyzes the error data and the MTF data output by mass-production simulation system, and output analysis result of the statistical complex tolerance sensitivity. Furthermore, this paper reports the effect the sensitivity analysis result confirmed by the mass-production simulation. - Constraint Representation and Reduction based on Lie Algebra in Assembly Model

Japanese, Tolerance is a very important parameter for all products to keep stable the product performance with low manufacturing cost. However in optical products, it is very difficult to predict the productivity , optical performance and complex sensitivity of tolerance for mass-production. To solve the above problems and to increase efficiency of manufacturing time and to reduce cost, This study develops the statistical tolerancing system and enables the quantitative analysis of optical performance with productivity before manufacturing. In this paper, we propose a concept of Virtual PT System (PT : Production Try) for optical products such as SLR Lenses. And we report a development of the mass product simulation system based on Monte-Carlo methods according to the proposed concept. Furthermore, we report reliability results based on simulations. - Geometrical characteristics of machined shape for computer aided operation planning

The objective of this paper is to characterize the machined shape, reflecting characteristics of the machining process such as the cutting edge and the machine tool motion, for linking between the machining features and machining operation. We propose a model of the machining process based on the form-shaping function proposed by Reshetov and Portman and identify the characteristic parameters of the machining process. We can also classify the characteristics of the machined surface from the viewpoint of the removal volume, the machined surface and the contacting shape between the required surface and the cutting edge during a cutting motion.

English, International conference proceedings, It is recognized that manufactuing information data shearing technology plays a very important role for global manufacturing activity. In order to establish manufacturing information data sharing, we propose "Manufactuing Resource modeling" at second phase of manufactuing information data shearing technology.
In this research, the modeling terget of manufacturing resource is machine tool. First, we compare Portman's Form-Shaping System notation, D-H symbolic notation, and S-U symbolic notation for their notations of rigid link mechanisms for machine tools. Also we propose the representation of kinematic models of machine tools based on ISO TC184/SC4 STEP kinematic models. - Feature based modeling of machining process products

English, International conference proceedings, In this paper, we propose feature models of a machining operation and machined surface, which correspond directly to the machining process model. The feature model of the machining operation is proposed from the viewpoint of the dimension of a macro cutting tool, the dimension of feed motion, and the number of enveloping constraints. The machining feature is also proposed from the viewpoint of the removal volume (tool swept shape), machined surface (enveloping tool swept shape), and the contacting shape between the required surface and cutting edge during one cutting motion (unit-shaping element). We proposed the abstract model of the machining process and the abstract model of operation planning which could represent the linear equations. We also pointed out that there are only 15 types of machining operations. - Contact constraint representation and its reduction in kinematic model of assembly

English, International conference proceedings, In order to check the kinematic performance of an assembly, a kinematic model of assembly using contact constraint representation in configuration space is needed. In this model, the motion of a component resulting from the imposed contact constraint is represented by the region in configuration space. However, it is difficult to derive the motion of the assembly because many constraints make the kinematic model of assembly too complex. In order to derive an equivalent minimum model of the kinematic model of an assembly, and to decrease the computational complexity, a constraint reduction procedure for the kinematic model of assembly in configuration space is proposed as follows: first, mapping rules of the kinematic model are proposed in order to realize the mapping from a feature-based kinematic model to a kinematic model in configuration space. Second, constraint reduction procedures in configuration space and a method for deriving the minimum kinematic model in configuration space are proposed. Third, based on the constraint reduction procedure in configuration space, feature-based constraint reduction is proposed by introducing a virtual feature; it is confirmed that TTRS reduction rules are valid feature-based constraint reduction rules. Using this reduction procedure, a method for deriving the feature-based minimum kinematic model is proposed. Fourth, using the feature-based minimum kinematic model and the mapping rule of the kinematic model, a method for deriving the minimum kinematic model in configuration space is proposed. Finally, in order to confirm the usefulness of the proposed constraint reduction, it is applied to an example of the kinematic model of assembly. - 鏡筒工学製品における統計的公差設計システムの開発(第1報)

Japanese, With kinematic analyses of assembly, it is difficult to derive the motion of the assembly because many constraints make the kinematic model of the assembly complex. In order to derive an equivalent minimum kinematic model for specific components, a constraint reduction procedure and reduction rules based on configuration of contact relations are proposed as follows : first, mapping rules of the kinematic model are proposed in order to realize the mapping from a (feature-based) kinematic model to a kinematic model in configuration space. Second, constraint reduction procedure in configuration space is proposed. Third, based on this constraint reduction procedure and the mapping rules, feature-based constraint reduction and reduction rules are proposed by introducing virtual feature. Finally, in order to confirrn the usefulness of the proposed method, it is applied to kinematic analysis of assembly. - Characteristics of Machining Operation and Machined Shape by Form Shaping Function

Journal of the Japan Society of Precision Engineering, 64, 5, 758, 762, The Japan Society for Precision Engineering, 1998
Japanese, Process planning for machined parts typically requires reasoning about machining features. However, such machining features do not generally take into account a micro-level geometric characteristics of contacting shape between the required shape and the cutting tool, and the macro-level geometrical characteristics of removal volume. Therefore these machining features do not correspond directly to machining operations. The objective of this paper is to capture the fundamental characteristics of machining process and make suitable machining process models based on them. First, a model of the machining process based on the form shaping system theory proposed by Reshetov is constructed. Second, the characteristics of machined surface are the number of parameters in the family of the instantaneous positions of the cutting points, the machined surface, and the contact shape between the locus of the cutting edge in a cutting motion (named macro cutting tool) and the machined surface, are proposed. The characteristics of machining process are the number of macro cutting tool parameters, the number of feed directions in machining operation, and the number of enveloping constraints are also proposed. Finally, the abstract model of machining operation and the abstract model of operation planning which can represent, the linear equations are proposed. - A Kinematic Model of Assembly using Contact Constraint Representation in Configuration Space(3rd Report) : Introduction of Time into Contact Constraint Representation

Japanese, In order to check the kinematic performance of an assembly, a kinematic model of assembly using contact constraint representation in configuration space was proposed in previous paper. In this model, the region of motion without collision is derived in configuration space from the imposed contact constraint. However, it is difficult to represent the motion since time is not taken into consideration. The objective of the research described in this paper is to introduce time into this kinematic model. This is accomplished as follows : first, by introducing configuration-time space, an expansion of the contact constraint representation is proposed. Second, based on this representation, a method for deriving the region for the position and orientation of the components in an assembly is proposed. - Constraint reduction eased on virtual feature in assembly model

INTERNATIONAL JOURNAL OF MACHINE TOOLS & MANUFACTURE, 37, 10, 1465, 1473, PERGAMON-ELSEVIER SCIENCE LTD, Oct. 1997
English, Scientific journal, In this paper an inspection method for geometrical tolerances for measurement with coordinate measuring machines (CMM) is proposed. It is indisputable that manual measuring methods cannot be applied for measurement with CMM. We also show that the usual procedure for inspection with CMM is inadequate for the implementation of ISO geometrical tolerances. The proposed model for calculation of the constraint substitute element ensures that inspections are carried out in accordance with ISO tolerance requirements, in which relationships between features and datum are implicitly defined. It is proposed to apply geometrical constraints that explicitly represent these relationships by means of fitting the mathematical form of the constraint substitute element. The resultant mathematical equations clearly illustrate tolerance design intent and can be applied with the small displacement screw (ISO/TR 10 360-1: Coordinate metrology--Part 1: Definitions and applications of the fundamental geometric principles) for inspection of the workpiece. This technique allows inspection to be performed in accordance with ISO geometrical tolerance. (C) 1997 Elsevier Science Ltd. - 最小実体公差方式が適用された場合の幾何公差の検証方法

Japanese, In this paper, in order to check the kinematic performance of an assembly, a kinematic model of assembly using contact constraint representation in configuration space is proposed. In this model, the motion of a component resulting from the imposed contact constraint is represented by the region in configuration space. The proposed kinematic model is constructed by the following steps. First, a contact constraint representation between any two specific geometrical elements of two components in configuration space is introduced. Secondly, an expansion of this representation to that of a multiple-component assembly is proposed. Thirdly, the representation of the relation of constraints in configuration space is proposed. Finally, based on these representations, a method for deriving the region for the position and orientation of the components in an assembly is proposed. - Geometrical characteristics of machined shape for computer aided operation planning

Journal of the Japan Society of Precision Engineering, 62, 5, 722, 726, The Japan Society for Precision Engineering, 1996
Japanese, A method of inspecting geometrical tolerances is important from the economic and qualitative viewpoints in coordinate measuring. However, there are some problems with CMM inspections based on ISO geometrical tolerances, due to the lack of a mathematical representation of the relationship between a toleranced feature and datum systems. No mathematical representation makes it impossible to evaluate the geometrical deviation of the related feature from a measured data set. In the first report, an evaluation method for related features with geometrical constraints in coordinate metrology was proposed. However, the proposed method could not be applied to the evaluation of related features under Maximum Material Condition. An inspection method using a computer model of the functional gauge (called the virtual gauge) is proposed in this report. The relationships between the geometrical elements of related features, datum, tolerance specification, measured data set, and functional gauge are represented in a formal description language EXPRESS. Computer experiments are conducted to verify the results and the validity of this method. - Gepmetrical Evaluation of a Composite Feature in Coordinate Metrology (1st Report) : Basic Concepts and Formulation

Japanese, In coordinate metrology, when a certain geometrical relation between features is specified due to functional requirements, it is sometimes necessary to evaluate them as a lump. Such evaluation method, however, has not been well developed. In this paper, therefore, a lump of features is defined as a composite feature and its concept is described. In addition, an evaluation method of a composite feature has been proposed. It is based on fitting in position and orientation between a composite feature model and measured data sets, which are obtained by the measurement of a part using coordinate measuring machines. Two-plane and two-cylinder composite features have been given and formulated as concrete examples of a composite feature. Computer experiments have also been performed in both examples and validity of the method has been confirmed. Proposed method is easy to be extended to any other cases. - An Infromation Model of Cutting Tools for Machining Center in Tool Assembly : Representing Models of Parts Structure, Assembly, Nominal Size and Real Size

Journal of the Japan Society of Precision Engineering, 62, 5, 717, 721, The Japan Society for Precision Engineering, 1996
Japanese, This paper deals with representing an information model of cutting tools for machining center to be used in a tool assembly. To comply quickly with requests from machine tools, FMS restricts machining work in machine tools, and each machine tool stores a number of cutting tools in its tool magazine. When more cutting tools ate needed, the costs of the tools become higher. To reduce the cost, there should be a tool management system which can automatically perform tool search and tool assembly. To make this system, there must be a tool database which can provide information necessary for those operations. In the present study, by introducing STEP technology and using EXPRESS and EXPRESS-G, the authors design an information model of cutting tools, thereby representing models of such basic tool database as parts structure, assembly, nominal size and real size. - An Estimation Method for Perpendicularity of Motion of Vertical Milling Machine by Model of Machine Tools

Japanese, In this paper a formulation by which perpendicularity of motion of vertical milling machine is evaluated, is shown. By using it, an estimation method for perpendicularity of motion between X-, Y- and Z- axis based on the master block measuring is proposed. The proposed method has following characteristics : (1) the perpendicularity of motion of X-, Y- and Z- axis is estimated without interference of setting posture of cutting tool, since the geometric error components is derived from driving planes which is calculated by measured points on master block, (2) perpendicularity of motion is estimated without interference of setting errors of master block, since the geometric error components are derived by inner products of normal vectors of driving planes which are independent of coordinate system on machine tools, and (3) since the model of machine tools with geometric errors is constructed of the driving motion and the perpendicularity of motion only, it is more simple to estimate the perpendicularity of motion between X-, Y- and Z- axis. - Virtual assembly using STEP data

Japanese, In the geometrical tolerance standards, related features are defined by the spatial relationship between datums and toleranced features. This relationship, therefore, must be taken into consideration for inspecting workpieces, which are designated on their drawings as related features. In this paper, an evaluation method for related features with geometrical constraints in coordinate metrology has been proposed. Geometrical constraints in position and orientation, which are formulated as linear equations, has been used in this method, which is based on the small displacement screw model. The results obtained by the proposed algorithm have also been analyzed in comparison with existing related standards. Computer simulation has been performed on some cases to verify the results and validity of the method has been confirmed. - Design Method of Tool Database for Tool Use Planning

Japanese, This paper deals with a design method of a tool database to be used in tool use planning. To increase the efficiency of the tool use in a flexible automated manufacturing system, it is necessary for the tool database to support information used in the whole field of the tool life cycle and in the tool use. A management system sharing with some tools in some machine tools and using them, can make the best use of tool capacity. For the realization of this system, the tool use needs information to select tool instance and to deploy it in the place just in time, based on tool status and machining schedule. An activity model of such a system for FMS is constructed for clarifying requirements for a tool database. Then to design such a tool database for satisfying the requirements, this study introduces an object-oriented method such as STEP technology, and implements the database using EXPRESS, C++, and object oriented database system. - Method of offset surface generation based on configuration space

Zhang Tong, Onosato Masahiko, Tanaka Fumiki, Proceedings of JSPE Semestrial Meeting, 2022S, 493, 494, 02 Mar. 2022
Nowadays, most of the strategies that commonly used to represent dynamic machining are based on three-dimensional (3D) geometric models and its motion with time steps information. These existing methods cause user to use shorter intervals, larger iteration number and longer calculation time if you need more precise result. We proposed a system to represent tool-workpiece engagement situation of dynamic machining process by four-dimensional (4D) geometric model based on Spatio-Temporal space. In the last report, the T-map method was proposed to simplify cutter-workpiece engagement analysis in 4D space. However, T-map method is more suitable for the situation between a static and a moving 3D object. This requires the user to convert the motion of workpiece to the cutter. Therefore, a method was considered for computing the general intersection between tool-occupied region and 4D mesh workpiece. Considering versatility, the boundary intersection determination method checks each pair of tetrahedrons and discusses case by case and get the intersection condition of tetrahedrons. However, it takes a lot of times for traversing all the tetrahedrons and analyzing according to the intersection situation. For accelerating the computation, parallel processing was introduced for optimizing preprocess and intersection determination steps., The Japan Society for Precision Engineering, English - 橋梁点検・保守のための国際標準に基づく橋梁情報モデルとそのweb配信システム(第15報)—HDF5を用いた大規模橋梁維持管理情報モデルデータのweb配信と時系列点検情報の表示

A captive balloon system named InfoBalloon has been developed as a system for collecting and distributing disaster information. In the disaster, information and communication service may break down by congestion of communication line, destruction of base stations, disconnection of cables, and so on. Therefore disaster area residents will fall into informational isolation. As a new emergency communication approach to solve these problems, we have investigated a method for the information distribution by flashing LEDs loaded on InfoBalloon.

In this study, key decision for the creation of production plans are defined as production-planning attributes. Production-planning attributes correlate complexly in production-planning problems. Traditionally, the production-planning problem splits sub-problems based on experiences, because of the complexity. Such approaches make solution space over-restricted and make it difficult to find a better solution. We have proposed ZDDs' network for addressing larger production-planning problems. The network can be created by linkages of ZDDs that express constraints in individual sub-problems and between sub-problems. In this paper, we describe a solution searching method for the restricted solution space represented by the ZDDs' network., The Japan Society of Mechanical Engineers, Japanese - A bridge information model based on International standards and a web contents providing system for bridge inspection and maintenance:Extension of BIM International Standards for archiving degradation data and the implementation of web delivery function

To realize high accurate machining process with high productivity, it is necessary to create machine specific NC data, which are current machining process data, in order to take into account physical and kinematic characteristics of individual machine tool. However, machine dependent NC data prevent reusing the data to other machine. In this research, generic CNC interface for applying individual machine tools is proposed to realize advanced machining, which is feature-based and machine independent using STEP-NC and STEP-NC machine tool model. STEP-NC remedies the shortcomings of current NC data., The Japan Society of Mechanical Engineers, Japanese - 1P1-H01 Behavioral Stability Evaluation of a Captive Balloon for a Disaster with the Motion Simulation(Search and Rescue Robot and Mechatronics (1))

A captive balloon system named InfoBalloon has been developed as a system for collecting and distributing disaster information. To support a disaster area, the captive balloon has to be stably moored. However, height, position and posture of the captive balloon are in danger of changing by wind in mooring. So it is necessary to evaluate behavior of the balloon in various wind conditions and methods of mooring to develop steadier InfoBalloon. We know the motions of the balloon are different depending on the conditions of the mooring point, so we evaluate the balloon motion of each mooring condition under changing wind direction and wind speed with the mooring simulator. Finally, we simulate rotation around the axis of symmetry of the balloon., The Japan Society of Mechanical Engineers, Japanese - 103 A study of synthesizing planning of production system to adapt to dynamic changes : Study of search method using Zero-Suppressed Binary Decision Diagram

Dynamic changes in manufacturing sites influence whole production planning. Therefore, production planning should be treated as comprehensive. However, the production planning has been treated as separate, such as process planning, production scheduling aad so on. In this study, we use Zero-Suppressed Binary Decision Diagram (ZDD) to represent only combinations satisfying the constraints in the comprehensive solution space. By searching in the ZDD, feasible solution can be obtainedコn this paper, we describe how to solve the dynamic production planning problem using the ZDD. Experimental results demonstrate that the ZDD can create and represent only feasible combinations adapting to dynamic changes, quickly., The Japan Society of Mechanical Engineers, Japanese - D025 Comprehensive representation of feasible combinations of alternatives for dynamic production planning using Zero-suppressed Binary Decision Diagram

TAKAHASHI Keita, ONOSATO Masahiko, TANAKA Fumiki, Manufacturing Systems Division Conference, 2013, 89, 90, 11 Mar. 2013
Dynamic changes in manufacturing production sites make current production schedule infeasible and inaccurate. In these cases, some parts in plans consisting of production planning are changed to obtain the plans adapted to these changes. In this study, we refer to these parts as optionality in production planning. In related research about production planning, optionality is preliminary set. However, this fixed optionality may not be suitable for certain cases, such as the case of having different factories, products and so on. In this study, we have analyzed optionality in production planning so far. In this paper, we develop new replanning model based on the optionality., The Japan Society of Mechanical Engineers, Japanese - 2A2-N08 A Study on Internal Structure Estimation of Collapsed Houses : Constructing the Digital GAREKI Library by Collapsed House Simulation under Different House Structures and Shaking Conditions(Search and Rescue Robot and Mechatronics (2))

At the time of earthquake, it is important to obtain information on the internal structure, such as position of free space and fragile part in the collapsed houses, in rescue operation. However, it is difficult to know the internal structure from external information alone. Therefore, this study aims to establish a method for estimating the internal structure of collapsed houses. In this paper, we report that we make some different house models of structure and adhesion strength for collec collapsed house data. We construct the digital GAREKI library by making various collapsed house model, changing a seismic waveform as shaking conditions., The Japan Society of Mechanical Engineers, Japanese - 2A2-N06 A Study on Quantitative Evaluation of the Interaction between Rubble and Rescue Robots(Search and Rescue Robot and Mechatronics (2))

In order to develop rescue robots suitable for disaster site, it is necessary to establish a method to evaluate mobility of rescue robots in rubble. However researchers are unable to do running tests of rescue robots in rubble for lack of collapsed houses in real world. Therefore this study creates a rescue robot and rubble virtually for running tests in cyber field. For collecting knowledge about rubble and rescue robots, this study presents a method to evaluate changes in rubble structure due to running effect by a virtual rescue robot and analyzes relations between rubble structure and running performance of a virtual rescue robot., The Japan Society of Mechanical Engineers, Japanese - 2A2-N07 A Study on Short Range Prediction of Strong Wind Aloft for Using Safely a Captive Balloon(Search and Rescue Robot and Mechatronics (2))

A captive balloon system named InfoBalloon has been developed as a system for collecting and distributing disaster information. There is possibility of losing safety of captive balloon in the strong wind. So it is necessary to avoid operating InfoBalloon in the strong wind based on short term weather forcast and local weather forcast. This paper proposes a method of short range prediction of strong wind aloft using Kalman Filter. Then, we set an error-adjusted prediction of maximum wind speed so as to decrease operation risk. We can decide stop or resumption of InfoBalloon mooring by comparing the maximum value by the prediction with the given value of regulation. Finally, we evaluate the InfoBalloon operation rule based on the prediction method in an assumed use of captive balloon., The Japan Society of Mechanical Engineers, Japanese - 204 Generating machining information based on machining feature with annotation from 3D annotated model and NC data

Annotations such as GD&T (geometric dimensioning and tolerancing) and surface roughness included in 3D annotated model are needed for machining or inspection process. However, when annotations in 3D annotated model are used at downward process, it is necessary to associate machining area with annotations. The purpose of this study is to generate machining information based on machining feature with annotation from 3D annotated model and NC data. In this study, at first, feature candidates are searched in 3D annotated model. Then, these feature candidates are matched with the machining feature from NC data. The generated model can be used for process planning or on-machine path planning., The Japan Society of Mechanical Engineers, Japanese - 203 A Study on Representing Five-Axis Cutting Processes by Using Four-Dimensional Mesh Model
KAMEYAMA Hirotaka, ONOSATO Masahiko, TANAKA Fumiki, Manufacturing Systems Division Conference, 2012, 31, 32, 07 Mar. 2012
In the fields of machining process, 3D models are used for the purpose of representing motions of tool and workpiece. However, 3D models can't describe changes of state to time direction continuously, so representing machining process efficiently is difficult. The objective of this study is to represent 5-axis cutting processes explicitly by using 4D mesh models, which can describe changes of state to time direction continuously. In order to show the availability of 4D representation, tool and workpiece are defined as "4D models of accumulated volume" which have information of motion records. In this report, 4D mesh models are obtained from time-series data of 3D voxel models which are made from 5-axis cutting simulation. Generated 4D mesh models are observed as 3D models by cross-section extraction. Also, cutting areas are obtained by collision detection between tool and workpiece., The Japan Society of Mechanical Engineers, Japanese - 1A2-J05 A study on structuring inside space of rubble and evaluating the mobility of rescue devices : Evaluation of rescue devices' accessible area from outside of rubble based on migratory difficulty index(Search and Rescue Robot and mechatronics)

In order to develop available rescue devices, it is necessary to make them run in various types of rubble and evaluate their mobility statistically. However, the evaluation under collapsed houses in real world is not enough. Therefore, our research group has enabled to create a lot of piles of virtual rubble model by physical simulation and to get their quantitative characters by methods based on geometric models. This study has established a method to structure internal working space for rescue devices as a path network. In addition, this study suggests a method to evaluate largeness of inside space through which rescue devices can access from outside space of rubble with Gareki-space Migratory Difficulty Index., The Japan Society of Mechanical Engineers, Japanese - 1A2-I05 Archiving images from a camera mounted on a captive balloon and retrieving scene information(Search and Rescue Robot and mechatronics)

Captive balloon systems named InfoBalloon have been developed for collecting and distributing disaster information. This paper proposes a method for making an image archive with direction and time information. And also an idea for searching and showing image information for users is discussed. Information about direction is put by data which is estimated using quaternion rotation and SIFT matching on a virtual sphere centered on a pan-tilt camera. To classify images, the sphere is subdivided and each image is set out. Image searching is processed using the classified images. Search range is set by user and images in the range are shown. And also we will propose a method for estimating oscillation of InfoBalloon using the gap of the specified value and the value which is estimated., The Japan Society of Mechanical Engineers, Japanese - 1A2-J06 A Study on Space Deformation Index for Internal Structure Estimation of Collapsed Houses(Search and Rescue Robot and mechatronics)

Space Deformation Index is evaluation index to evaluate compression or/and deformation of the living space, based on the analysis of the digital rubble model., The Japan Society of Mechanical Engineers, Japanese - 103 Integrated Model of Structure and Shape for Machine Tool System and Inverse kinematics calculation : Simulation and collision detection for machine tool system with robot system
TERASHIMA Takahiro, TANAKA Fumiki, ONOSATO Masahiko, Manufacturing Systems Division Conference, 2011, 23, 24, 16 Mar. 2011
In machining process, especially multi-axis NC machining with robots, it is necessary to simulate the motion for confirmation of NC data, robot motion data, and collisions of their systems. In such case, there are two problems; 1) There is no common integrated model of kinematics and shapes for machine tools and robots. 2) It is difficult to calculate inverse kinematics with machine tool system with robot system. To solve these problems, an integrated model of kinematic model and shape model for machine tool system with robot system based on STEP (ISO10303) was proposed. However, it is difficult to calculate inverse kinematics for machine tool system with robot system. In this study, a unified solving method which can calculate inverse kinematics for machine tools and robots is proposed. Collision detection using OPCODE is also proposed. To demonstrate the effectivity of proposed method, a motion simulation system with collision detection is developed., The Japan Society of Mechanical Engineers, Japanese - B18 Integrated Model of Structure and Shape for Machine Tools and Inverse kinematics calculation : Application for machine tool system with robot system

In machining process, especially multiaxis NC machining, it is necessary to simulate the motion for confirmation of NC data. Recently, machine tool systems consist of not only machine tools but also auxiliary devices such as robots, then the systems are complicated. In such case, there are two problems; 1) There is no common integrated model of kinematics and shapes for machine tools and robots. 2) There is no unified solving method of inverse kinematics with machine tools and robots. In this paper, to solve these problems, an integrated model of kinematic model and shape model for machine tools and robots based on STEP(ISO10303) is proposed.

This paper proposes the analysis system of NC data based on a feature information representation. This model is a next-generation CMC control language (ISO 14649) which contains machining information such as machining features, machining operation, and machining conditions enabling feature-based description of the machining process.

In order to evaluate the mobility of rescue devices statistically, it is necessary to make the devices run in various types of rubble. However, there are few test rubble fields in the real world. Our research group has enabled to create a lot of piles of virtual rubble model by physical simulation and to get their quantitative characters by some methods. This study structures the devices' working space in a virtual rubble model as path network connecting Local Maximum Vacant Spheres. In addition, this study suggests an evaluation method with a mobile difficulty index and enables to evaluate the mobility of the devices in the virtual rubble model., The Japan Society of Mechanical Engineers, Japanese - 1A2-C25 A Study on an Omni-directional Bird's Eye Image System with a Camera Mounted on a Captive Balloon

A captive balloon system named InfoBalloon has been developed as a system for collecting and distributing disaster information. In this report, an effective use of multidirectional images by a pan-tilt camera mounted on InfoBalloon is discussed. Captured images should be integrated into an omni-directional image. However, view direction of the camera changes in the wind, so specified pan-tilt value to the camera cannot be used for image integration. Each image is pasted on a virtual sphere screen based on quaternion of positional interrelation derived by Scale-Invariant Feature Transform (SIFT) without using specified pan-tilt value to the camera. Finally, an omni-directional image is generated from the virtual sphere that images are pasted. Moreover, we also propose omni-directional image showing system that enables users to see the image in a sense near the viewpoint of the camera., The Japan Society of Mechanical Engineers, Japanese - 2316 Designing Dynamic Objects based on Four-Dimensional Geometric Modeling

In usual design process with a three-dimensional CAD system, it is difficult to decide a shape, position and orientation, and motion of a design object simultaneously. Four-dimensional geometric modeling enables us to deal with a dynamic three-dimensional design object as a static object in a higher-order space of space-time extension. The authors have been developing a four-dimensional geometric modeling system which weaves four-dimensional mesh models from successive three-dimensional voxel models. This report presents discussion on how four-dimensional geometric modeling effects both the concept of design objects and design processes., The Japan Society of Mechanical Engineers, Japanese - K-033 A development of a Repository System for sharing distributed SCORM Complaint contents in e-learning system : Implementation of a Viewing History Management Function for Streaming Video Contents

Tanaka Fumiki, Shimokawabe Haruki, Igari Shiji, Onosato Masahiko, Manufacturing Systems Division Conference, 2009, 41, 42, 09 Mar. 2009
In a manufacturing system, the digital tools such as CAD, CAM, and simulation systems has been usually used. Then, communication among these systems frequently occurs. However, interoperability among heterogeneous software systems and tools is generally not available. Moreover, existing machining information models lack the necessary information and are described in their own formats. Consequently, many models which include the same information exist. There is another problem that various simulations for a virtual machining system and adaptive control for a real machining system are inacculate. To solve this problem, a digital machining information (DMI) model to support a real-virtual machining system is proposed in this study., The Japan Society of Mechanical Engineers, Japanese - C24 Based Integrated Model of Structure and Shape for Machine Tools and Its Application to 5-Axis Machining (Second Report) : Modeling system and Inverse kinematics calculation

In machining process, especially multiaxis NC machining, it is necessary to simulate the motion for confirmation of NC data. However, in such case, there are three problems; 1) It is no common integrated model of kinematics and shape for machine tools. 2) It is no modeling system of integrated machine tool model. 3) It is no unified solving method of inverse kinematics. To solve these problems, an integrated model of kinematic model and shape model for machine tools based on STEP(ISO10303) is proposed. A modeling system to generate an integrated model to associate kinematic model with shape model is developed and the integrated model for 5-axis machining is generated as an example. A motion simulation system including a unified solving method of inverse kinematics using Groebner Basis is also developed., The Japan Society of Mechanical Engineers, Japanese - 1304 NC data analysis based on CNC data model for acquisition of machining knowledge

NC data analysis is one of the efficient methods for acquisition and retaining the machining knowledge. However, code interpretation of actual NC data (ISO 6983) differs among CNC controllers. Typical examples of interpretation difference are fixed cycle orders which are significant for the machining of hole feature. Thus, it is difficult to analyze actual NC data directly. In this research, for obtaining the machining knowledge, actual ISO 6983 NC data is transformed into a next-generation CNC control language (IS014649) which contains the technical information. In this report, the method for extracting Workingstep which consists of Machining feature, Machining strategy from NC code depending on the controller based on Form-shaping function is described., The Japan Society of Mechanical Engineers, Japanese - 2P2-B02 Accessibility evaluation of rescue robots using rubble models of collapsed houses

In order to use for the design and assessment for the rescue robots, it is necessary to analyze rubble. To get huge amount rubble's models with speed, we have constructed rubble with only balance, which is decided by location of vertexes and center of gravity. Recently physics engines are developing rapidly, and are able to treat real-time simulation with physical effects. After evaluating three typical physics engines, which are PhysX, Havok FX, gaming engine in Blender, the rubble construct simulator is developed by using PhysX. The simulator makes it possible to construct and handle rubble with physical effects., The Japan Society of Mechanical Engineers, Japanese - 2A2-A03 A Study on GIS-based Association of Aero-Robot's Flight Records and Aerial Videos

Aerial videos are effective to obtain the situation of a stricken area at disaster outbreak. It takes, however, much time and cost to analyze video contents for finding out the scene in which the damage of a watching point is confirmed. We have been developing a metadata generation method in which a necessary point in an aerial video is retrieved quickly by using aerial videos associated with moving camera data of positions and orientations. The positions and orientations of a moving camera are acquired by GPS and INS installed on a helicopter. We judge whether a destination is included in the view cone of a camera from orientations of a camera and a position of a destination to be it and calculate the time when a destination is recorded., The Japan Society of Mechanical Engineers, Japanese - Universal Pointing and Cyber Annotation for Complex Manufacturing Space

It takes, however, much time and cost to analyze video contents for finding out the scene in which the damage of a watching point is confirmed. We have been developing a metadata generation method in which a necessary point in an aerial video is retrieved quickly. We use aerial videos associated with moving camera data of positions and orientations. The position data sequence and the orientation data sequence are respectively converted into a NURBS curve for noise reduction and data compression. The camera moving trace represented by the NURBS curves is used for visible judgment of the watching point. We examined the proposed method with a hand-moving camera instead of aerial camera. A future plan is to apply the method to aerial video recorded by an unmanned helicopter., The Japan Society of Mechanical Engineers, Japanese - 災害情報データベースのための空撮ビデオ映像とGISの連携手法に関する研究

There's likely to problem not to inherit the skills and knowledge about manufacturing and designing. Annotation function in CAD software could embed such informations, however it requires extra operations and the locations depends on the CAD system. So we develop a universal representation method that indicates regions on the 3-D model. This method uses the expression of 3-D locations called as Discrete Direction Expression and extends it. Forthermore we made a user-interface device to indicate 3-D regions on the 3-D model intuitively by the use of mixed reality. Therefore, we suggests a universal representation method for three dimensional partial regions throughout the model lifecycle and suitable interface device., The Japan Society of Mechanical Engineers, Japanese - 2417 A Study on Universal Pointing in the Mixed Work Space with Entities and Representations

Then, in our study, we aim at the development of the system which an opinion of a participant in an argument is positively reflected by making the target clear using three demension pointing device. We called this system "Universal Pointing System (UPS)". UPS is capable of pointing the object regardless of entities or representations using three demension pointing devices. Furthermore it is possible to add easily devices and applications because the entire system is going to be designed with the client-server model., The Japan Society of Mechanical Engineers, Japanese - 1106 A Study of Machined Surface Group Generation based on Tool Attitude Evaluation

Cutting speeds on the cutting edge of Ball-nose end mill vary from the bottom to the top of the cutting edge, thus the portion of the cutting edge that has a suitable cutting speed should be used in the finish milling process. This paper describes a procedure of generation of surface element groups that can be machined by the high performance portion of cutting edge in the finish milling process. For this purpose, performance values of cutting points on the cutting edge are proposed. The tool attitude to the surface element is evaluated by the ratio of the area machined by the high performance portion of cutting edge based on proposed performance values. The tool attitude having maximum area of the surface elements that can be machined with the high performance is derived, and a set of surface elements that can be machined by the high performance portion of cutting edge for the tool attitude is obtained as the surface element groups., The Japan Society of Mechanical Engineers, Japanese - 1P1-S-094 Three Dimensional Measuring of Collapsed Structures based on Epipolar Plane Images(Rescue System and Rescue Engineering 2,Mega-Integration in Robotics and Mechatronics to Assist Our Daily Lives)

Recently, high precision machining and high-speed cutting are required in the die and mold machining. To solve this problem, die and mold machining by 3+2 axis control machining, which is a method of indexing by 2-axis rotary motion and machining by 3-axis feed motion, on 5-axis machining center is proposed in this paper. In this machining process, the list of indexing angle should be determined automatically, because the shape of the die and mold is very complex to determine the angle by an machining operator. Therefore, the main objective of this research is automatic determination method of the list of indexing angle for the die and mold machining. Firstly, we propose the calculation method of optimum indexing angle candidates for required machining surfaces using normal vectors of the surfaces and cutting edge. Secondary, we propose the machinable area evaluation method of calculated indexing angle based on inverse offset method with state flag. Finally, we show the examples to demonstrate the effectiveness of the proposed methods., The Japan Society of Mechanical Engineers, Japanese - 5軸NC工作機械による主軸傾斜曲面加工法に関する研究(第2報) : 状態フラグ付き逆オフセット法による未加工部位の導出

To support a cutting tool management system in distributed manufacturing industries, there must be a cutting tool database, which can provide information necessary for that purpose. This paper deals with the methodology to construct a cutting tool database and to manage of cutting tool information for distributed cutting tool management system using network. In the past study, by introducing STEP technology and using EXPRESS and EXPRESS-G, we designed an information model of cutting tools, thereby representing models of such basic tool database as parts structure, assembly, nominal size and real size. We proposed an EXPRESS early binding XML for capturing the nature of tool data model, and for generation the serialization format of an EXPRESS data model, and evaluating its usefulness., The Japan Society of Mechanical Engineers, Japanese - Working Tool model based on Machining Process Modeling for Process Planning

This paper deals with feature models of machined shapes and a machining operation, which correspond directly to the machining process model. So far, the feature model of machined shape was modeled as the machining features, for example, hole, pocket, slot, etc. However, only tool behaviors are derived from giving the tool and the cutting motion to the machine tool. Therefore, we introduce the behavior model of cutting tool, working tool, as a feature models of machined shapes to connect the machining operation and machined shapes. The working tool consists of the swept macro tool, the envelope of the swept macro tool, and the working edge. The feature model of the machining operation, operating step, is also proposed from the viewpoint of the dimension of a macro cutting tool, the dimension of feed motion, and the number of enveloping constraints., The Japan Society of Mechanical Engineers, Japanese - 形状創成関数に基づく加工フィーチャ導出のための加工プロセスのモデル化(第一報) : Operating Step とWorking Tool の提案

Japanese - CAM System Consisting of Hierarchical Modules Based on Cell-Constructed-geometric-Model
KANAI Satoshi, TANAKA Fumiki, KISHINAMI Takeshi, SAITO Katsumasa, Journal of the Japan Society of Precision Engineering, 52, 11, 1927, 1933, 05 Nov. 1986
A new style of CAM system which consists of hierarchical modules was developed, and as a basic geometric model for the system, the Cell-Constructed-geometric-Model (CCM) was proposed. These enables us to decompose the CCM into the several Machining Face Groups (MFG) which are created by the same cutting operations, to determine various information about machining, to generate cutter path for each MFG and to check and distribute NC data to machine tools in an interactive way. The CCM which is based on a rational Bézier interpolation, is efficient to make and edit the MFG, and to generate cutter path. In this paper, the structure and functions of these hierarchical modules and an example of the processing are described. And the concept and contribution of the CCM to these modules are also shown., 公益社団法人精密工学会, Japanese - Cell-Constructed-geometric-Model (CCM) and Its Modelling System
KANAI Satoshi, TANAKA Fumiki, KISHINAMI Takeshi, SAITO Katsumasa, Journal of the Japan Society of Precision Engineering, 52, 10, 1808, 1814, 05 Oct. 1986
The Cell-Constructed-geometric-Model (CCM) is proposed as a new conception for the data representation of geometric model. The CCM consists of three-dimensional array of some finite Cells. The Cell means a unit volumetric solid bounded by six curved surfaces, and is regarded as an extended idea of bi-cubic parametric surface interpolation to a tri-cubic one. The interpolative method of the CCM is a rational cubic Bézier's. Therefore, with the CCM, it is possible to represent a closed volumetric solid bounded by some analytic surfaces and sculptured surfaces using the same data structure. This paper describes the mathematical formulation and the internal data structure of the CCM. Then the application of the CCM to the geometric model for CAM system, Finite-Element-Analysis, and calculation of weight and volume of a solid, are considered. Finally, developed geometric modelling system and methods of modelling to make the CCM interactively are described, and a modelling example of the CCM is shown., 公益社団法人精密工学会, Japanese - CCMモデリングプロセッサーにおける自由曲面を含む部品形状のモデリング方法

The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec), 2017, JapaneseRescue robot simulation is an effective method for evaluating the performance of rescue robot in various rubble fields. However, simulating a rescue robot in a large rubble field such as a collapsed house needs a lot of time, since it needs to process a large number of rigid bodies and joints. This study accelerates the rescue robot simulation by using multi-core CPU and GPU on a physics engine. To consider the effect of GPU about rescue robot simulation, this study measures the processing time of two situations, including only rescue robot or a rescue robot and rubbles, on two computers equipped with different GPU. Result of the experiments show that the use of GPU, especially high-speed GPU, is effective for a situation which includes a rescue robot and rubbles. Based on the results, this study simulates a rescue robot in a collapsed house in real-time using GPU.

TAKAHASHI Keita, ONOSATO Masahiko, TANAKA Fumiki
The Proceedings of Manufacturing Systems Division Conference, 2015, Japanese
In this study, key decision for the creation of production plans are defined as production-planning attributes. Production-planning attributes correlate complexly in production-planning problems. Traditionally, the production-planning problem splits sub-problems based on experiences, because of the complexity. Such approaches make solution space over-restricted and make it difficult to find a better solution. We have proposed ZDDs' network for addressing larger production-planning problems. The network can be created by linkages of ZDDs that express constraints in individual sub-problems and between sub-problems. In this paper, we describe a solution searching method for the restricted solution space represented by the ZDDs' network. - S1410102 A study on CNC interface using STEP-NC

The Proceedings of Mechanical Engineering Congress, Japan, 2015, Japanese
The G-code (ISO 6983) focuses on tool path information mainly, and it has limited information. STEP-NC (ISO 14649) includes information of tools, tool paths, workpieces, and features. Then, STEP-NC allows bidirectional data flow between CAD/CAM and CNC without any information loss. However, STEP-NC is not used in industries widely. In this study, CNC interface using STEP-NC is developed. In this system, the target feature is a freeform feature, which represented by the Region surface. Through the implemented system and machining simulation results, the superiorities of STEP-NC are also showed. - S1410103 Tool swept volume generation method using tool swept profile curves for multi axis machining with errors
ARAI Wataru, TANAKA Fumiki, ONOSATO Masahiko
The Proceedings of Mechanical Engineering Congress, Japan, 2015, Japanese
In modern part manufacturing, in order to achieve high performance products, the accuracy required for machined parts with complicated shape is higher. Multi-axis machine tools are usually used for such machining parts. However, there is the problem that machined errors always occur on machined parts and sometimes interfere with the required accuracy of machined parts. For this reason, it is necessary to derive machined errors of the machined parts, before actual machining. In the previous report, the tool swept volume generating method based on the tangency condition was proposed. The solving method of the self-intersection problem was also proposed by our study. In this report, the tool swept conditional equation is simplified without any approximation and the case study is performed. - 1A1-T06 Investigation of visible light communication using multi-colored LEDs for information distribution by a captive balloon

A captive balloon system named InfoBalloon has been developed as a system for collecting and distributing disaster information. In the disaster, information and communication service may break down by congestion of communication line, destruction of base stations, disconnection of cables, and so on. Therefore disaster area residents will fall into informational isolation. As a new emergency communication approach to solve these problems, we have investigated a method for the information distribution by flashing LEDs loaded on InfoBalloon. This paper describes algorithms for receiving flashing LEDs by using a smart phone camera, and method to increase transmission quantity by using multi-color LEDs. - A Study on Evaluating the Traversing Performance of Rescue Robots Moving over Rubble Fields with Various Features

A number of rescue robots have been developed for quick and safe rescue operations at the time of earthquake. In order to develop rescue robots suitable for disaster site, it is necessary to test traversing performance of rescue robots in various rubble fields. However, the inaccessibility of real rubble fields makes it difficult to accumulate enough knowledge about rubble and rescue robots. This study aims to construct a software system which enables to evaluate traversing performance of rescue robots in virtual rubble fields. In this paper, we present the configuration of this system and we show example of knowledge about rubble and rescue robots, which is obtained through using this system. In addition, we report the result of traversing performance tests in real and virtual rubble fields to demonstrate the effectiveness of this system. - Representation of Cutting Edge Motion Trajectory in Ball-End Milling Based on a Four-Dimensional Mesh Modeling

A captive balloon system named InfoBalloon has been developed as a system for collecting and distributing disaster information. To support a disaster area, the captive balloon has to be stably moored. However, height, position and posture of the captive balloon are in danger of changing by wind in mooring. So it is necessary to evaluate behavior of the balloon in various wind conditions and methods of mooring to develop steadier InfoBalloon. We know the motions of the balloon are different depending on the conditions of the mooring point, so we evaluate the balloon motion of each mooring condition under changing wind direction and wind speed with the mooring simulator. Finally, we simulate rotation around the axis of symmetry of the balloon. - 103 A study of synthesizing planning of production system to adapt to dynamic changes : Study of search method using Zero-Suppressed Binary Decision Diagram
TAKAHASHI Keita, ONOSATO Masahiko, TANAKA Fumiki
The Proceedings of Manufacturing Systems Division Conference, 2014, Japanese
Dynamic changes in manufacturing sites influence whole production planning. Therefore, production planning should be treated as comprehensive. However, the production planning has been treated as separate, such as process planning, production scheduling aad so on. In this study, we use Zero-Suppressed Binary Decision Diagram (ZDD) to represent only combinations satisfying the constraints in the comprehensive solution space. By searching in the ZDD, feasible solution can be obtainedコn this paper, we describe how to solve the dynamic production planning problem using the ZDD. Experimental results demonstrate that the ZDD can create and represent only feasible combinations adapting to dynamic changes, quickly. - Error compensation for geometric errors of three axis machine tools by modifying the NC code (2nd report):Estimating the parameter of error model by measuring the reference plane

It becomes apparent that problems in shape data quality cause tremendous economic loss in mechanical industries. In order to resolve these problems, automotive manufacturers jointly create a guideline to improve the quality of product shape data. This paper describes the development of ISO 10303-59, the international standard for product shape data. The standard has been proposed to ISO and is being developed by Japan to capture the quality of product shape data correctly and to promote the circulation of the quality information. The scope, anticipated usage scenarios, management of shape d... - N_040 Learning Assist and Management platform based on Distributed Application service for e-learining system

Aerial videos are effective to obtain the situation of a stricken area at disaster outbreak. It takes, however, much time and cost to analyze video contents for finding out the scene in which the damage of a watching point is confirmed. We have been developing a metadata generation method in which a necessary point in an aerial video is retrieved quickly. We use aerial videos associated with moving camera data of positions and orientations. The position data sequence and the orientation data sequence are respectively converted into a NURBS curve for noise reduction and data compression. The... - 2417 A Study on Universal Pointing in the Mixed Work Space with Entities and Representations

When the targets of an argument are mixed, as a product model in computer made with CAD and that's prototype, there are often difficult situations to understand what object is pointed and disucussed. Then, in our study, we aim at the development of the system which an opinion of a participant in an argument is positively reflected by making the target clear using three demension pointing device. We called this system "Universal Pointing System (UPS)". UPS is capable of pointing the object regardless of entities or representations using three demension pointing devices. Furthermore it is pos... - 1302 Development of A Universal Representation Method for Three Dimensional Partial Regions and the Suitable Interface Device

設計工学・システム部門講演会講演論文集, 02 Aug. 2005, Japanese
There's likely to problem not to inherit the skills and knowledge about manufacturing and designing. Annotation function in CAD software could embed such informations, however it requires extra operations and the locations depends on the CAD system. So we develop a universal representation method that indicates regions on the 3-D model. This method uses the expression of 3-D locations called as Discrete Direction Expression and extends it. Forthermore we made a user-interface device to indicate 3-D regions on the 3-D model intuitively by the use of mixed reality. Therefore, we suggests a un... - 1106 A Study of Machined Surface Group Generation based on Tool Attitude Evaluation

Cutting speeds on the cutting edge of Ball-nose end mill vary from the bottom to the top of the cutting edge, thus the portion of the cutting edge that has a suitable cutting speed should be used in the finish milling process. This paper describes a procedure of generation of surface element groups that can be machined by the high performance portion of cutting edge in the finish milling process. For this purpose, performance values of cutting points on the cutting edge are proposed. The tool attitude to the surface element is evaluated by the ratio of the area machined by the high performa... - 1P1-S-094 Three Dimensional Measuring of Collapsed Structures based on Epipolar Plane Images(Rescue System and Rescue Engineering 2,Mega-Integration in Robotics and Mechatronics to Assist Our Daily Lives)

Recently, high precision machining and high-speed cutting are required in the die and mold machining. To solve this problem, die and mold machining by 3+2 axis control machining, which is a method of indexing by 2-axis rotary motion and machining by 3-axis feed motion, on 5-axis machining center is proposed in this paper. In this machining process, the list of indexing angle should be determined automatically, because the shape of the die and mold is very complex to determine the angle by an machining operator. Therefore, the main objective of this research is automatic determination method... - Research for transforming from ISO6983 data to ISO14649

So far, the feature model of machined shape was modeled as the machining features, for example, hole, pocket, slot, etc. However, only tool behaviors are derived from giving the tool and the cutting motion to the machine tool. Therefore, we introduce the behavior model of cutting tool, working tool, as a feature models of machined shapes to connect the machining operation and machined shapes.

The subject of this study is to represent the positions, orientations, and forms of dynamic objects and to utilize the representations in design and planning with respect to them. In a four-dimensional space representing a spatio-temporal space, four-dimensional geometric models are constructed with tetrahedrons which determine the boundary of 4D body. Based on this shape data schema, a four-dimensional geometric modeling system has been developed. The proposed method and the developed system were evaluated by applying to three problems: collision avoidance problem of moving objects, representing 5DOF cutting with ball-end milling, and water-level changes in the tsunami disaster.

Thus, we can think that each manufacturing system is realized on the accumulation of knowledge application by many experts. Now, many industrial companies try to preserve such knowledge for factory design and operation in order to keep or improve the manufacturing ability. The authors had an idea that Virtual Manufacturing Systems (VMS) can be applied for knowledge acquisition/storage/utilization.For categorizing manufacturing knowledge, three viewpoints were introd...

NCシステムのオープン化は、加工システム構築の自由度を増すために、徐々に進められている。このオープン化の流れにおいて、加工システムの高機能化、知能化は、重要な課題である。加工システムの高度な自動化、知能化を達成するには、加工システムが加工システム自身を認識できなければならない。すなわち、オープンNCシステムでは、NCシステムに別の工作機械がつながれていても、すぐにその工作機械の構造と動作をNCシステムに与える方法を提案する必要がある。そこで、本研究では、リンク構造間の相対運動とリンク構造の幾何情報を保持した工作機械機構モデルをISO 10303で規格化されているEXPRESS言語を用いてS-U表記法に基づきモデル化する。次に実際の工作機械に対し、その機構を表現するパラメータを求め、NCシステムと工作機械との通信方法を確立し、有効性を確かめるとともに、NC機能の高度化の一例として、加工シミュレーションシステムをパソコン上で実装する。以上を目的として、昨年度の研究成果を踏まえ、以下の結論を得た。1) 知能型オープンNCの加工検証機能と作業領域検証機能の実現アルゴリズムの導出加工検証機能と作業領域検証機能のアルゴリズムを、工作機械の機構モデルを参照する形でアルゴリズムを実現した。2) 知能型オープンNCのパーソナルコンピュータによる実現・評価3)で提案したアルゴリズムを用い、パーソ...

In this research a formulation by which perpendicularty of motion of vertical milling machine is evaluated, is shown. By using it, an estimation method for perpendicularity of motion between X-, Y- and Z- axis based on the master block measuring is proposed. The proposed method has following characteristics : (1) the perpendicularity of motion X-, Y- and Z- axis is estimated without interference of setting posture of cutting tool, since the geometric error components is derived from driving planes which is calculated by measured points on master block, (2) perpendicularity of motion is esti...

様々な形状加工へのニーズや高能率、高精度加工への要求から多軸工作機械による加工法に関する研究が多数行なわれている。しかし、多軸工作機械は工場で実際に使われている例が少ない。その理由としては、五軸制御工作機械などに代表される、工具姿勢の制御が可能な工作機械に対し、工具の姿勢を全て考慮し、工具干渉の回避を可能とする工具オフセット面生成法が困難なためである。そこで、本研究では、工具の位置と姿勢を同時に表現するために、配位空間を用いた方法を提案、工具の位置と姿勢を同時に表現するとともに、工具干渉回避を可能とするオフセット面の配位空間における表現を提案し、上述の問題点を解決する。このため、工具の位置と姿勢を同時に表現する配位空間を用い、工具オフセット面の理論的解析及び数学的表現を行ない、それを実現するためのアルゴリズムの提案及び実装を行なう。上記の目的で研究を行ない、以下の結論を得た。1)工具オフセット面生成及び工具経路生成法の調査:多軸工作機械における工具オフセット面生成法及び工具経路生成法の調査を行ない、従来法の問題点を明らかにした。2)配位空間の表現法の調査と配位空間による工具オフセット面のモデル化:工具の位置と姿勢を同時に表現する配位空間を用い、工具オフセット面の理論的解析を行なうと共に、配位空間の表現法や配位空間で用いられているアルゴリズムの検討を行なった。また、工具オフセッ...

高精度加工を実現するためには、工作機械の運動機能を計算機で表現し、加工運動シミュレーション、解析などを行い補正することが必要となる。しかし、実際に計算機を用いて加工運動シミュレーション等を行うには、工作機械の構造などの計算機表現が十分でなく、加工運動シミュレーションや補正法などなされていない。その理由としては、工作機械の構造と運動を表すためには、リンク構造間の相対運動をマトリクス表現で表す方法では、人間が概念的に理解する為、及び計算機により工作機械の運動シミュレーションを行う上で適切な形式ではない、が挙げられる。本研究は、工作機械の構造と運動を、工作機械の各構成要素の構造や構成要素間の運動を詳述する情報モデルとして表現しそれを用いて工作機械における計算機支援システムを実現することを目的としている。上記の目的で研究を行ない、以下の結論を得た。1)工作機械の運動モデルの理論の調査、検討工作機械の運動モデルについて、従来研究の調査により工作機械の運動モデルとして表現すべき情報は、リンク間の相対運動及び運動座標系間の一つのリンク上における位置関係である。この観点から、座標系の設定法として、形状創成関数、D-H記法、S-U記法を比較し、本研究ではS-U記法が適していることがわかった。2)オブジェクト指向言語による工作機械の運動モデルの情報モデル表現法に関する検討上述した手順により求めら...

従来、設計と加工の情報伝達の必然性、CADとCAMとの有機的結合が叫ばれてきたが、依然として困難な状態にある。それは、設計(CAD)モデルが形状の幾何の観点や機能の観点からの表現しか行われていないためである。この問題点を解決すべく加工特徴という概念が導入されてきたが、これまでは、工具を中心にした分類や形状特徴を中心にした分類方法であり、加工モデルに必要な加工作業の観点での表現が行われていなかった。そこで本研究は、加工単位作業を十分に支援するモデルとして加工特徴を定義し、加工作業を加工特徴を用いて記述することを目的としている。本研究では、以下の手順で研究を遂行した。1)単位加工作業表現に関する理論的検討単位加工作業の抽象化を、V.T.Portmanの形状創成機能モデルの考え方を基本として工作機械、工具、加工運動を含めた加工作業モデルとして抽象化を行った。この加工作業モデルと加工特徴を対応させるように、加工特徴のモデル化を行った。2)基準面、データム面を考慮した加工順序の表現方法基準面、データム面に関する情報は、加工特徴間の空間配置関係に依存している。この情報を基に、同一取り付け状態の加工特徴をグループモデルとして表現し、加工順序の表現法提案した。3)加工作業モデルを用いたモデリングシステムの試作と評価以上のモデルのモデリングシステムをコンピュータ上で実現し、穴加工における加工作...

It is generally agreed that higher level descriptions to refer to familiar features are needed to describe engineering components and machining operations, and one of the primary roles of features is the interface between design and process planning (or machining operation). The features are an abstraction idea from application viewpoints.For example, the Design feature is the shape abstraction from the designview, on the other hand, the Machining feature is one from the machining operation view.Especially the Machining feature is a very important idea for connecting the productmodel and it...

The machining simulation technique is very important for computer aided manufacturing system and NC data verification. If we can forecast the machining phenomena, for example, cutter collision, cutter removal shape, removed volume and cutting force by using simulation techniques, a more high level computer controlled machining system can be realized. Some research on machining simulation based on conventional geometric modeling techniques such as CSG or Breps have already been done.However, these approaches were time consuming and complex because of the massive set operations between workpi...
