    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.

    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.

    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.

    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 (excluding the machine tool errors) with the triangles on the error tool swept volumes (including the machine tool errors).

    According to a recent study, it has been said that “lessons learned” is one of the most important and “value added” aspects of the project management lifecycle. However, it has been reported that it is often the most ignored part of finishing a project. Various reasons have been offered for this phenomenon. This article describes the systematic approach to initiate the project review on the specific project identified for requiring the formal quality audit based on the use of project management information system for having the execution date fixed by the independent quality reviewer with the project manager. Then, the project review process is started by retrieving the lessons learned data from the lessons learned repository, which were collected from the previous project reviews for the relevant ERP implementation projects, for the preparation of conducting the project document review and project stakeholder interviews. A case study methodology was applied to the historical lessons learned data of the ERP implementation projects conducted by the solution provider for their customers in the various industries in Japan, which were retrieved for a period of four years from 2014 to 2017 to analyze how the lessons learned collected from the project reviews of the earlier projects were reused in those of the succeeding projects conducted during the period. Use of lessons learned based on the past project review results was found to be effective in focusing on the specific areas projected for improvement during the processes of conducting the project document review and project stakeholder interviews, as well as putting together the practical recommendations for the findings to finalize the results of the project review, which were to be formally presented and submitted to the customer as the results of the quality audit.

    物理エンジンを用いた家屋倒壊シミュレーションは,救助活動の場であるがれきのデータを取得する手段として有効であるが,家屋モデルは多数の剛体を接続して構成されるため処理には時間がかかる.本研究では倒壊シミュレーションを高速化するため,4種類の物理エンジン(Open Dynamics Engine, Bullet Physics Library, PhysX 2.8.1, PhysX 3.4)について処理速度の評価を行った.その結果PhysX 3.4でGPUを用いた処理が最も高速であるとわかり,この処理を倒壊シミュレーションに適用することで,倒壊家屋1軒から成るがれきのリアルタイム生成が可能となった.加えて処理に必要なGPUメモリを推定し,規模を30軒に拡大することで,倒壊家屋相互の干渉が含まれる大規模ながれきフィールドの作成を可能にした.

    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.

    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.

    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.

    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.

    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.

    Here we propose an accurate and robust method for large-area land-use and land-cover (LULC) mapping using multi-temporal optical data. The conventional method for LULC classification usually uses time-series data at regular intervals to consider the seasonality of LULC. However, high-resolution optical data have considerable seasonal biases, making it difficult to use time-series data. Our basic idea for the accurate classification of LULC using high-resolution optical satellite data is to implement a classification for each scene considering seasonality first, and to then integrate multi-temporal classification results. In the per-scene classification, we accurately estimated the class-conditional spectral-seasonal densities of observation values from training data by conducting a kernel density estimation (KDE), and we used the densities in a Bayesian inference to obtain the class posterior probability. After the multi-temporal per-scene classification, we calculated the classification score by integrating class posterior probabilities in multi-temporal scenes. We conducted an 8-class classification for the entirety of Japan with 10-m spatial resolution using 1,876 scenes from the Advanced Visible and Near Infrared Radiometer type 2 (AVNIR-2) low-cloud-cover data, and we evaluated the accuracy of the classification by conducting a cross validation test and comparing the results to that obtained with existing methods: maximum likelihood classifier (MLC) and support vector machines (SVMs). The evaluation results showed that the overall accuracy of the proposed method is the best of all of the methods examined.

    ABSTRACT: This paper presents a method of four-dimensional (4-D) mesh modeling that generates a 4-D mesh model from a series of three-dimensional (3-D) voxel models. To reduce the size of model data and the computing time for mesh generation, the authors have been developing 4-D Mesh Weaver which generates a 4-D mesh model in a compact data model by incrementally loading 3-D voxel files. For efficient processing in 4-D Mesh Weaver, a 4-D triangulation table was preprocessed for fast processing, and an algorithm of 4-D mesh generation was improved so as to avoid the redundant vertices of mesh tetrahedrons.

    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.

    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.

    This paper describes a new land use and land cover (LULC) classification method for classifying multi-temporal high-resolution satellite data in large areas. The classification method uses combined value of both reflectance of a pixel and its observation date as an input data, and calculates its probability distribution among all LULC classes via Bayesian inference based on a generative model estimated by kernel density estimation. This method can be easily applied to multi-temporal data to exploit phenological change information of vegetation, even if available multi-temporal data have a seasonal bias. In this paper, we conducted the classification over the entire land mass of Japan, using the multi-temporal data observed by the Advanced Visible and Near Infrared Radiometer type 2 (AVNIR-2) aboard the ALOS, and we evaluated its accuracy in comparison to conventional methods.

    To generate optimal machining information, an automatically customizable micro process planning system that reflects the change of properties of an actual machine tool is proposed. 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 decision tree method. Cutting conditions were determined from a feasible regression equation. Regression equations and selection rules of these equations were generated from the database by regression tree method. The example of micro process planning using the generated algorithm is also shown.

    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.

    Change detection using satellite data is frequently used in cases of natural disasters to identify the location and extent of the damage. However, current practical analysis for disaster monitoring largely depends on manual analysis by experts, creating a bottleneck of data that hinders effective and prompt response. This paper proposes an automatic change detection system that can execute entire processes of change detection without the intervention of human experts. The proposed system employs a knowledge-driven system based on ontology. The system stores knowledge modules, each of which can extract information or make an inference. At the time of change detection, the system selects the appropriate knowledge modules and constructs a Bayesian network for the inference of target change by interpreting the semantics of the target change and knowledge modules using ontology. The system extracts information and makes an inference, yielding probability images that indicate the confidence degree of the inference of the target change. This paper presents a demonstration of the proposed detection system by applying it without any modifications in the system to two cases of disaster monitoring: a mudslide and a flood.

    EARTH OBSERVING MISSIONS AND SENSORS: DEVELOPMENT, IMPLEMENTATION, AND CHARACTERIZATION II 8528 2012年 [査読有り][通常論文]
     
    Change detection is a fundamental approach in utilization of satellite remote sensing image, especially in multi-temporal analysis that involves for example extracting damaged areas by a natural disaster. Recently, the amount of data obtained by Earth observation satellites has increased significantly owing to the increasing number and types of observing sensors, the enhancement of their spatial resolution, and improvements in their data processing systems. In applications for disaster monitoring, in particular, fast and accurate analysis of broad geographical areas is required to facilitate efficient rescue efforts. It is expected that robust automatic image interpretation is necessary. Several algorithms have been proposed in the field of automatic change detection in past, however they are still lack of robustness for multi purposes, an instrument independency, and accuracy better than a manual interpretation. We are trying to develop a framework for automatic image interpretation using ontology-based knowledge representation. This framework permits the description, accumulation, and use of knowledge drawn from image interpretation. Local relationships among certain concepts defined in the ontology are described as knowledge modules and are collected in the knowledge base. The knowledge representation uses a Bayesian network as a tool to describe various types of knowledge in a uniform manner. Knowledge modules are synthesized and used for target-specified inference. The results applied to two types of disasters by the framework without any modification and tuning are shown in this paper.

    The paper presents an approach to an engineering of "gareki", which generally means destroyed or disordered structures in Japanese. Gareki has never been a subject for both natural sciences and engineering. Therefore we have had less scientific knowledge about gareki, while search and rescue activities in earthquake disasters need it much. 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.

    The recognition of concepts that we human beings are able to locate within satellite imagery requires analysis based on the particular context using knowledge. In this paper, we present a supervised pixel-based classification approach toward utilization of the classification results in knowledge-based satellite data interpretation system. The proposed approach is based upon a generative model, which is able to output the classification results with their probabilities and subsequently utilize them in detailed analysis. The experiment of classification was performed to demonstrate characteristics of the approach.

    This paper describes a method of object recognition in terrestrial laser scan data of complex scenes. By local 3D shape matching between the CAD model mesh of the object and the laser scan data of the scene, the existence of the object is recognized and its location and orientation in the scene are extracted. Spin-images are used for shape matching. In this paper, some techniques for applying spin-image matching to the terrestrial laser scan data are proposed. They include robustness improvements for the scan noise and the differences in vertex densities by normal averaging and uniform point sampling, and efficient calculation by using multi-resolution images and geometric point filtering. © 2012 CAD Solutions, LLC.

    In this paper, we propose a method for matching, combinations extraction and configuration of mesh models for assembly and geometric modeling. Given two mesh models, a graph is first generated for each model. This graph, called a "feature-graph", represents abstract geometry information and connections of segments (local regions) for the model. Next, a set of pairs of segments which can be matched are extracted by performing sequential matching tests on the graphs. Finally, using the resulting pairs, the configuration between the models is determined by phased registrations keeping previous contact condition. An example of application to assembly modeling is included. © 2011 Springer-Verlag.

    This paper proposes a new framework for automatic interpretation, especially for change interpretation, in order to implement insightful and versatile interpretation like manual interpretation. The framework considers remote sensing data analysis as a knowledge information processing. For handling large amount of knowledge on computers consistently, the framework employs double-layered knowledge structure; ontology and heuristic. The ontology is a conceptual dictionary about remote sensing domain, and heuristic is experimental knowledge containing uncertainty. Additionally, this paper introduces the method for constructing Bayesian network using knowledge, and inferring target objects and changes using it. An experiment of change detection is conducted to demonstrate our framework.

    To generate optimal machining information, a machining database and operation planning algorithm have to be customized for an actual machine tool based on knowledge of a skilled planner. In this paper, a method to update a machining database from NC data is proposed. The database is updated by adding machining information extracted from NC data based on tool path analysis. A method to generate a database oriented planning algorithm from the machining database based on a decision tree method is also proposed. Machining strategy, cutting tool and cutting conditions are determined based on the algorithm and k nearest neighbor method.

    This paper suggests a new automatic change detection approach using image-object-based contextual inference. The approach first detects changed areas, and then infers what happened there. The inference process uses knowledge based on a change detection process performed by humans. It enables flexible and intuitive description of the change detection process. In this paper, we describe the results of case studies on automatic change detection using the Advanced Visible and Near Infrared Radiometer type-2 (AVNIR-2) onboard the Advanced Land Observing Satellite (ALOS, nicknamed "Daichi").

    This paper describes a method for flexibly controlling the properties of a given multimaterial tetrahedral mesh for finite-element analysis. Our method is based on multiresolution techniques. A given mesh is first subdivided and then simplified so that the resulting mesh satisfies the user-specified thresholds for mesh properties (element size, shape, valence, and geometric tolerance). Once the simplification is completed, mesh resolution and density can be modified quickly by using level of detail.

    This paper proposes CAD data integrated machining system for realizing advanced machining which is feature-based and machine independent. STEP-NC remedies the shortcomings of current NC data and is basic data structure for realizing the advanced machining system. To realize STEP'NC based manufacturing systems, it is necessary to perform machining feature extraction and data complementing of machine specific parameters. In this paper, a method to assist manufacturing feature extraction is proposed, which extracted an area of a product corresponding to a manufacturing feature based on the cutting tool approach direction. For data complementing of machine specific parameters, value setting method is also proposed. This method sets a default value of optional attribute using EXPRESS-X.

The development of the rescue search devices is aimed at practical deployment in the future so that the development researchers must have taken a pragmatic approach. It was crucial that researchers took every opportunity to demonstrate them in the presence of first responders and that they had contacts with several volunteer incumbent firemen who offered practical comments on the developed devices. Such comments will be used in the next stage of the development of rescue search devices. © 2009 Springer London.

    This chapter introduces R& D results for aerial robot systems for urban search and rescue (USAR). Different types of aerial robot system have been developed and effectively combined so as to offer a quick and continuous service for disaster information gathering. First, autonomous helicopters collect disaster situation data from the sky for first decision making in USAR planning. Then, a blimptype robot system and a cable-driven robot system survey victims under collapsed houses by detecting faint signs of life. As a continuous information service, a captive balloon system with a monitoring camera presents bird's-eye-views of the disaster area, and relays wireless communication among working teams on the ground. These robot systems and other developed technologies are integrated to provide a total solution for quick information gathering from the sky for USAR activity support. The availability of aerial robot systems was demonstrated in field tests conducted at Yamakoshi village. © 2009 Springer London.

    The current NC data format (ISO 6983) puts restrictions on CNC machine tools because the NC data are specified in a low-level language, describing machine axis motion and some machine instructions. STEP-NC remedies the shortcomings of current NC data and has many advantages. However, to realize STEP-NC based machining systems, it is necessary to perform machining feature extraction, to generate machine-specific information, and to create a relationship between coordinate systems without disturbing data porting. This paper proposes the solutions for these problems and introduces a prototype of STEP-NC based process planning and a machining system.

    In this paper, we propose a triangular mesh deformation method based on dimensions. By specifying the type of dimensions, the regions defining the dimensions, and the target dimensions, the mesh is automatically deformed so that it satisfies the target dimensions. Mesh deformation is based on space-based deformation using barycentric coordinates. The deformation handle, which consists of a set of triangular prisms, is automatically created by mesh segmentation, simplification and offsetting of simplified mesh. In deformation, the deformation and fixed spaces are assigned to each prism in the handle, and the mesh is deformed by applying affine transformation to the control vertices and space-based deformation to the deformation space. Results for the mechanical parts show the effectiveness of our method. © 2008 CAD Solutions, LLC.

    Manufacturing in the digital age is deeply dependent on the information and communication technologies (ICT) and the manufacturing activities have been changing from direct operations by human operators to digital data exchanges by computers. It is fairly difficult for engineers and workers to understand the entire image of digital manufacturing activities. A concept of complex manufacturing space (CMS) introduces the duality of the physical world and the information world to manufacturing design, planning, control, and other activities. This paper explains the complex manufacturing space concept and some technical challenges for its implementation.

    To realize the articulate link between design and manufacturing, it is necessary to realize interoperable digital tools which represent the semantics of information independently of any implementations. It is necessary to assure that the quality of the shape information overcomes the limitation of interoperability of the shape information. In manufacturing, the interoperable CNC machining systems can be characterized as being capable of 1) seamless information flow; 2) feature based machining; etc. In this research, modeling and implementation of the Digital Semantic Model for 5-axis machining that fulfils the above requirements is proposed.

    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.

A feature of this research is that a resource circulation system is modeled as interaction between agents with behavioral preferences. These agents include users and product makers in this model. Each user individually purchases products and each product maker individually supplies products. These actions are carried out through a market. Then some simulation scenarios were set up. These scenarios differ in behavioral preferences of product makers. Next, life cycle simulation was carried out in each scenario.

    Increasing the robustness and flexibility of the toot path finding method may broaden the application fields of pocket machining. We aim to develop a path finding method for various applications. Through an integration of the entire tool path finding process, the method becomes not merely optimal to generate an efficient path but also robust enough to be applied to any system with any configuration. The flexibility of the devised method enables us to broaden the application fields of pocketing to fields such as prototype printed circuit board manufacturing. The devised method is applied to generate a clearing path for prototype printed circuit boards. The results verify that the method is concise and simple, but robust and flexible enough to achieve the optimal path in any configuration.

    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.

    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.

    Free-Form Deformation (FFD) is a popular method for deforming 3D geometric models. FFD first embeds the model in the parametric space defined by regular lattice (handle). Then by deforming the handle, the embedded model is deformed. However the FFD has following problems for engineering applications such as deformation of mesh models for Computer Aided Engineering (CAE): 1) It is difficult to make handle suitable for intended deformation type such as bend and twist, 2) it requires complicated manipulation to deform and 3) it can not explicitly specify the degree of deformations such as angle of bend. Therefore, in order to solve these problems, we present a parametric deformation method for mesh models. First, we propose an FFD based on barycentric coordinates (BCFFD). Then, we propose an automatic handle construction method for the BCFFD based on definition and classification of deformation types such as bend, twist and so on. Finally, we propose a parametric deformation method. Using our methods, the user can deform the mesh model by selecting deformation type and portions to be deformed, and by manipulating one or two deformation parameters.

    It is not easy to find an efficient method for tool path generation free from uncut regions. Offset-loop dissection method (ODM) based on the offset loop entity (OLE) concept enables the method to be implemented easily into the system at any condition regardless of the number of offsets, the number of intersections, and even the number of islands. Recognizing the robustness and flexibility of the ODM and realizing the fact that uncut regions exist if there is an intersection between a previous tool envelope and a current tool envelope, the ODM is extended to uncut region detection. For the adoption of the ODM, the tool envelope loop entity (TLE) is defined. This concept enables the offset curve generation method to be extended further as a distinctive method in which uncut region detection is done through an identical way of offsetting. To ensure the method works, a prototype system is implemented and evaluated with the tool path generation obviating uncut regions. The result verifies that the proposed method fulfils technological requirements for uncut free pocketing. © 2006 Elsevier Ltd. All rights reserved.

    Increasing the robustness and flexibility of the toot path finding method may broaden the application fields of pocket machining. We aim to develop a path finding method for various applications. Through an integration of the entire tool path finding process, the method becomes not merely optimal to generate an efficient path but also robust enough to be applied to any system with any configuration. The flexibility of the devised method enables us to broaden the application fields of pocketing to fields such as prototype printed circuit board manufacturing. The devised method is applied to generate a clearing path for prototype printed circuit boards. The results verify that the method is concise and simple, but robust and flexible enough to achieve the optimal path in any configuration.

Fragmented plans in operation planning are generated separately, although those generations are dependent each other. Advanced machining operations are directed to complicated and/or thin shape workpiece precision machining. This trend requires considering the interdependency among the partial plans.

    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 are dependent on CAD. We develop a system that can embed the information intuitively by the use of mixed reality. The device "XEONA" consists of 3D monitor, PHANToM haptic device and fuses them by half-mirror. Our system can obtain the shapes of the models as surface-model from CAD software seemlessly and represents it by OpenGL and PHANToM API. We developed a tool-independent expression for 3D locations using the codes by Hierarchical Triangular Mesh(HTM). Therefore, we suggests the system that embed the knowledge informations onto and retrieve it from 3D product models directly and intuitively based on XEONA.

In case the discussion of the model created using the CAD software, conversations including spatial infomation such as "I want this part is more right." are often occured. If you can point the "this part" of the model which exists on real space and virtual space using a pointing device without distinction, it will become more intelligible for a everyone in the discussion. And we call this system which can point a model without distinction of space Universal Pointing system. Then, we use a mouse, FASTRAK and MicroScribe as a device for pointing object. We aim at development for the system which can point a real object or a virtual object that was reflected on the screen etc. using these three devices. Moreover, the technique as, for which an exchange of data is made to a system using TCP/IP-was proposed.

    The study deals with an accurate cutting error prediction of end milling in the finishing operation. As it was indicated that the consideration of cutting edge roundness improves the accuracy of cutting force simulation, a new estimation method of cutting force has been proposed for end milling with the straight flute tools, based on the calculation of the actual depth of cut. The influence of cutting edge roundness was not considered in the conventional cutting error prediction. Then, the study proposes an extended estimation method of cutting error for the helical flute end mill. It is necessary to calculate the actual depth of cut with an accurate description method of workpiece surface since the amount of cutting error on workpiece surface usually changes with the height of a cutting flute. As a change in workpiece surface in machining is correctly estimated by the calculation of the actual depth of cut, the estimation of cutting error is attained by referring to the form of machined workpiece surface, which is left behind after the end mill passed. A prototype of simulation system is developed, based on the proposed method. The effectiveness of the proposed estimation method is demonstrated by making cutting experiments with helical flute end mill under the cutting condition of finishing operation. The predicted cutting error shows a good qualitative agreement with the measured one, thus the more accurate prediction of cutting error is realized by the proposed method.

    This paper deals with an accurate cutting force prediction method of end milling. Cutting condition with small feed rate is often adopted in finish machining. In such conditions, the depth of cut in the radial direction of end mill cannot be estimated accurately by conventional cutting force prediction methods. When the depth of cut is quite small, the error on workpiece surface and the displacement of cutting edge are regarded as dominant factors to determine cutting force. Then, two estimation models about tool deflection and elastic recovery named "Actual depth of cut" are introduced in ...

Furthermore, a new procedure of cutting force calculation is proposed in order to consider the effect of error on workpiece surface. The effectiveness of the proposed method is demonstrated by developing the prototype simulation system and making cutting experiments with straight flute end mill, where it is difficult to predict the cutting force by conventional simulation methods. The cutting force measured in the experiment shows a good qualitative agreement with the predicted one.

    The modularity is now considered as the key concept of the current manufacturing systems. The modularity was originally investigated in software engineering and it has never been examined in the context of manufacturing systems configuration. This paper firstly introduces five aspects of modules, which are segmentation, operation, encapsulation, independence, and interface, and then explains five relationships in manufacturing systems, which are cohesion, similarity, continuity, cooperation, and dependece. The concept of modularity in manufacturing systems is redefined by using the conceptual scheme of modularity for manufacturing.

    In the present study an objective method for evaluating work-related painfulness at a pectoral limb (that is an upper limb of human body) was derived from combining biomechanical and physiological evaluations. Flexions and extensions about an elbow joint with a tool in a hand were taken up for the work models with a pectoral limb. Experiments of the model works at five different positions were carried out by ten male subjects in order to evaluate physical and physiological burdens. On the basis of the experimental results an objective index of painfulness was defined as proportional to the magnitude of the physical load and inversely proportional to the level of the skin blood flow. And it was confirmed that the index of painfulness agreed well with the subjective evaluations. Copyright © 2000 Society of Automotive Engineers, Inc.

    In the conventional end-milling research, fixturing and machining plans in operation planning are generated separately, although those generations are mutually dependent. Advanced machining operations are directed to complicated and/or thin shape workpiece precision machining. This trend requires to consider the interdependency between machining and fixturing. This interdependency is dealt with in the newly developed coordination cycle where physical consistency and evaluation coherence are managed. This research paper presents a basic framework and procedure of the problem solving for coordinative generation of machining and fixturing plans. This paper also describes an example to demonstrate the effectiveness of the method.

    Using compliance is effective in assembly operations with positioning errors, so that it prevents excessive contact forces and guides a part to its goal. In this paper we present a systematic method to design a compliant hand appropriate to given assembly task. The desired end-point stiffness matrix is decided through the results of quasi-static analyses of contact states. The mechanical structure of a compliant hand is then designed based on the derived stiffness matrix. The validity of the design method is illustrated through an assembly simulation.

    For successful concurrent engineering, one should understand how each member of the design task carries out his processes in the organization. All task processes conducted in the design task form a kind of structure in which various factors are related to each other in a complicated way. The authors named this the organizational task processing structure (OTP structure). In this paper, the authors propose a method for OTP structure modelling, named ScoPy (Simultaneous and Collaborative Processing Systematization and Analysis). The definition of the Scopy object model for OTP structure is in...

    In conventional modeling, a design object is mostly described as a static and unique structure composed of entities. Such a static model only gives a snapshot of the design object on the specific aspect. For advanced product design, products should be modeled as both time-changeable and multiphase objects. To deal with machine behaviors, the changes of attribute values and relations of components should be described explicitly according as its history. Industrial products are now considered as multidisciplinary objects. Entities such as parts and units are inadequate to represent design objects with behaviors and multiphase in some integrated way. In order to extend the entitybased modeling framework so as to include behaviors and multiphase, the authors proposed the statebased modeling framework. The modeling primitive in the framework is called 'state'. Each state is described as a combination of the spatial region occupied, the time interval in which it exists, and a list of attribute values for the specified spatial region and time interval. Entities such as parts, units, and products are represented as the aggregation of states which are distributed in the space-time extent.

    Advanced information technology such as computer networking and 3D graphics is now forcing industrial companies to change their manufacturing systems to information-oriented ones. The authors propose an new approach to an advanced information infrastructure with manufacturing semantics by using virtual manufacturing systems. Virtual manufacturing systems have much potential to integrate manufacturing resources and activities distributed in computer networks. The paper also describes how virtual manufacturing systems will be applied to applications as the informational kernel with open architecture in advanced manufacturing systems.

    Concurrent, cooperative and consistent product design by multiple designers and engineers is a key concept for success in a quickly changing market. For such design, the product modeling system is considered to be the common work space that integrates both design activities and design information from multiple designers and engineers. In this paper a framework of feature-based modeling is proposed to support concurrent, cooperative and consistent product design involving functional design, machining, assembly and maintenance. The framework defines a mechanism for interpreting shape descriptions from the viewpoint of different applications into a unified representation. With this mechanism, designers and engineers can deal cooperatively with product shapes in an environment of concurrent engineering. Based on this framework, a feature-based modeling system has been developed and an example of implementation is briefly introduced.

    A consulting system for the body loads taken on individual joints while working has been developed using a kinetic analysis system of human body motions and a posture input device shaped like a robot, called CHAPLIN (Consultation by HAndling Puppet-Like INterface). CHAPLIN has 15 skeletal segments made of vinyl chloride resin, and 16 total degrees of freedom. The sensors are invisibly imbedded in the resin, thereby allowing the exterior form to be crafted so that postures are easily recognizable. The torques acting at body joints are calculated from the posture inputted to a computer and the consulter's anthropometric data. In the system real-time skeletal animation is displayed with colored visualization of the torque intensity about the joints. Based on both the CHAPLIN's posture and the torque intensity displayed, the consultation is conducted comparing the body loads corresponding to several postures during load liftings. As a result of consultations with 20 subjects, it was found that this system is very useful for enabling workers to understand how to improve their postures.

    Virtual manufacturing systems are integrated computer models that represent the precise and whole structure of manufacturing systems and simulate their physical and logical behavior in operation. Since each virtual manufacturing system is an aggregation of various computer hardware and software, it is necessary to develop a system architecture which defines functional components required for modelling and simulation, interfaces between components, virtual-real interactions, and system infrastructure. This paper deals with a modelling and simulation architecture for virtual manufacturing systems for the practical development and describes a method of modelling and simulation for distributed simulation of virtual manufacturing systems. © 1995 CIRP.

    Non-manifold models have been studied in order to represent and manipulate the shape of products in design and manufacturing processes consistently. Most developments of non-manifold modeling are based on the Radial-edge structure which has complicated structures and operations of topologies. In this paper, a new non-manifold modeling method based on cells, which is named Cell-model, is proposed. A Cell-model is composed of two prime concepts; Cells as topological elements and Cell-lists as adjacencies of Cells. Orders among adjacent Cells, which are essential for topological information, can he derived from a Cell-model by applying Switching functions to Cell-lists and chaining the selected Cells. A set of basic operators for handling topological structures of Cell-models are defined, and the basic concept of set operations in the Cell-modeling is explained with an example of modeling processes.

    This paper describes a concept of a central modeling system for time information and a methodology to realize it. First, the importance of developing temporal modeling systems which are commonly used by application programs is discussed from the viewpoint of computer-integrated manufacturing. After analyzing the diversity of temporal information to be considered, a unified representation method of various temporal information is proposed and its mathematical formalization is explained. According to the proposed approach, an experimental system, time information manager, is implemented. The system adopts J.F. Allen's method as a consistency management algorithm. The system is also extended so as to deal with cyclic time intervals, the multiple time axes, and qualitative information. It is applied to some present methodologies concerned with time information to evaluate the effectiveness of the proposed methodology.

    Summary: The concept of "Mechanism Diagram" is introduced in order to realize the quick understanding of mechanism in mechanical design. Mechanism Diagram is constituted by the connection of "symbolized elements with movement", which are derived by analyzing kinematic relations of mechanical elements in machines. A drawing system for Mechanism Diagram is also developed. The result of experiments by using it shows that Mechanism Diagram can remarkably reduce time for understanding a complicated mechanism. © 1992 CIRP.

    This paper describes a systematic method which can generate effective robot motion for handling constrained objects automatically. In this study, constraints which appear in the time of object manipulation are divided into following three parts. The first one is a natural constraint which is observed between an object and a base on which the object is constrained. Most of the natural constraints of industrial products are considered as a kinematic pair and this fact makes costraint problem simple. The second one is an artificial constraint which exists between an object and an end-effector ...

    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.

    Geometric errors of machine tools affect the quality of machined parts. In order to obtain high accuracy in the machining of parts, machined errors of a machined part should be estimated before actual machining. This paper describes a tool swept volume generation method for multi-axis machining with machine tool errors to derive a shape of a machined part and its machined errors. In this paper, the tool swept volume generation method based on the tangency condition and form shaping theory is proposed. To demonstrate the validity of the proposed method, case studies for 5-axis machining with the errors are also presented.

    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.

    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.

    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.

But it is difficult to use exhaustive methods because we have to choose the amount of safety stock to each warehouse from many choices. Existing method has a problem of computational cost for simulation to get evaluation value. In this study, we focus on Kriging to reduce the number of times for simulation. It is the method to predict solutions' value by approximating the relation between design variables and responses with some kind of functions. In this paper, we show the new method is more efficient than the existing method.

    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.

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 mooring conditions and decide optimal shape of the balloon and method of mooring to develop steadier InfoBalloon. We analysis aerodynamics characteristic of the balloon with computational fluid dynamics and develop a mooring simulator for InfoBalloon based on kinetics. With the simulator, calculation of the balloon behavior becomes possible before conducting a mooring experiment. Finally, we evaluate height, position and posture of balloon.

    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.

    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 Great East Japan Earthquake occurred on March 11, 2011 has forced us to change our images of Tsunami disaster by its overwhelming destruction. For mitigation of Tsunami disaster, it is necessary to define the basic facts about Tsunami disasters based on the observations and then analyze the requirement in development of new robot systems. In this report five images of robot systems against Tsunami disaster are suggested as basic for further discussion. Additional remarks on InfoBalloon and GAREK.I engineering applications to Tsunami mitigation are given at last.

    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.

    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.

    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.

    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.

    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.

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.

    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.

    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. The machining features and the process information are extracted from a traditional NC program based on a form-shaping function. The proposed analysis system is implemented using data mapping language EXPRESS-X between two sets of model data which are described in EXPRESS data modeling language. The implemented system is applied to the ISO 6983 NC data for the milling machine generated by commercial CAM software.

    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.

    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.

    InfoBalloon is the name of the captive balloon system which has been developed at Hokkaido University for collecting and distributing disaster information. InfoBalloon is intended for operations both in disaster time and ordinary time. Therefore, InfoBalloon should provide information services to residents in its territory community with long-term and stable operations. In this report requirements of captive balloons for realizing continuous services are firstly introduced and then technical problems to be addressed are discussed. To enable long-term and stable operations of InfoBalloon, a new balloon shape and tethering method for InfoBalloon have been developed. The balloon shape for the wind effect and the tethering method with three parallel wires and a pivot base keep InfoBalloon at required position in air against a wind with stable attitude. A breakage prevention system against heavy wind and thunder is also designed and now being implemented for safety and continuous operations of InfoBalloon.

    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.

    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.

In addition to these variations, models on its virtual system are made as well as real system. We need a conceptual scheme with which various descriptions on a manufacturing system could be integrated and managed consistently. In this paper a complex manufacturing space (CMS) is examined from the viewpoint of real-virtual duality in model description and implementation issues are briefly explained.

Study subjects on collapsed houses were categorized into five research fields: object modeling, forming process, analysis, human search methods and human rescue methods. As a key technology for connecting these fields, digital models of collapsed houses are studied from the aspects of measurement, construction, and analysis. Rubble forming processes are simulated with a large number of elements by using a physics engine and the spatial characteristics of the produced rubble models are analyzed in order to present the design requirements for developing rescue robots working in rubble.

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.

    Increasing the robustness and flexibility of the toot path finding method may broaden the application fields of pocket machining. We aim to develop a path finding method for various applications. Through an integration of the entire tool path finding process, the method becomes not merely optimal to generate an efficient path but also robust enough to be applied to any system with any configuration. The flexibility of the devised method enables us to broaden the application fields of pocketing to fields such as prototype printed circuit board manufacturing. The devised method is applied to generate a clearing path for prototype printed circuit boards. The results verify that the method is concise and simple, but robust and flexible enough to achieve the optimal path in any configuration.

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 diversification of consumer's needs and the shortening of product's lifecycle increase uncertainty about production volume and period. Manufacturing systems are now required to realize competitive and optimized ones which can be following a fluctuation of demand in the market. Therefore, we propose a methodology for designing manufacturing systems with adaptability for market trends. This methodology consists of two methods; namely, "manufacturing system modularization" and "implementation of improvement".

    Concurrent, cooperative and consistent product design by multiple designers and engineers is a key concept for success in a quickly changing market, For such design, the product modeling system is considered to be the common work space that integrates both design activities and design information from multiple designers and engineers. In this paper a framework of feature-based modeling is proposed to support concurrent, cooperative and consistent product design involving functional design, machining, assembly and maintenance. The framework defines a mechanism for interpreting shape descriptions from the viewpoint of different applications into a unified representation, With this mechanism, designers and engineers can deal cooperatively with product shapes in an environment of concurrent engineering. Based on this framework, a feature-based modeling system has been developed and an example of implementation is briefly introduced.

    Human body dynamography(HBD) is proposed as a convenient system for analyzing and evaluating human body motions specifically the torque acting at joints of a human body. Torque intensity is visually displayed using a color scale. A kinetic model of the human body, consisting of fifteen rigid cylinders equivalent to the body segments and the equations of motion, is derived to estimate each torque during joint action. A sequence of motions in both the frontal and sagittal planes is simultaneously taken by two video cameras, and the coordinates of individual joints are digitized with a PC. Visualization of torque was tested on the planar motions in a popular physical exercise of a Japanese radio program. Rings centered on individual joints were drawn on a skeletal model, and colored corresponding to the magnitude of torque. Torque was normalized by the cross·section area (Normalization 1) and volume (Normalization 2) of each segment. Additionally, HBD was compared with thermography to evaluate the normalizations.

    This paper describes a concept of a central modeling system for time information and a methodology to realize it. First, the importance of developing temporal modeling systems which are commonly used by application programs is discussed from the viewpoint of computer-integrated manufacturing. After analyzing the diversity of temporal information to be considered, a unified representation method of various temporal information is proposed and its mathematical formalization is explained. According to the proposed approach, an experimental system, time information manager, is implemented. The system adopts J.F. Allen's method as a consistency management algorithm. The system is also extended so as to deal with cyclic time intervals, the multiple time axes, and qualitative information. It is applied to some present methodologies concerned with time information to evaluate the effectiveness of the proposed methodology.

    製品設計から製造において,CAD, CAE, CAM, PDM, CNC工作機械などといったデジタルツールへの依存が増加している.そこで,近年のグローバル生産システムにおいて日本の優位性を保つためには,これらデジタルツールに基づき,加工不具合の迅速対応や,加工結果の正当な判断が可能となるトレーサブルな加工システムの確立が重要となる.しかしながら,現在のCAMからの出力データでは,NCデータ,図面,加工工程表など情報に関連性が無く,しかも意味的情報が無いため理解が困難となり,トレーサブルにならず,ヒューマンエラーの原因にさえなっている.その解決方法としては,技術的な意味情報であるフィーチャ情報,加工作業情報,工具情報・素材情報・加工機械情報などを統合し,関係付けを行い,一つのデータ構造で表現することが必要となる.本研究では,そのような要件を満たすモデルをセマンティック加工情報モデルとして提案した.セマンティック加工情報モデルは,EXPRESS, EXPRESS-X, Part28といったSTEP技術を応用してXMLで保存される.また,セマンティック加工情報モデルに基づくシミュレーションシステムや加工システムを開発した.さらに,従来のCAMシステムと提案システムのインタフェースシステムを開発した.すなわち,セマンティック加工情報モデルの基本要素であるworkingstepは,形状...

    一般設計学は、多くの産業分野で行なわれている多様な設計に関して、その本質を明らかにし、またその際に共通に成立するモデルを樹立することを目的として、理論・実験の両面より研究する学問である。本研究は、それの理論的測面の展開を目的として行なわれた。本研究においては、まず、従来の一般設計学である位相幾何学を用いた数学的モデルの精緻化を行ない、各定義・定理間の整合性を高めた。さらに概念の位相の構成を考えることによって、知能の発達・学習のモデルをこのモデル上で考察できることが明らかとなった。また、現実の設計を説明するために、メタモデルという概念を導入し、それによって現実の設計過定のモデル化を行うことで、現実の設計過程との対応をとることが可能となった。このことにより、一般設計学の設計過程モデルをCADシステムの構築に際しての脂導原理として用いることができた。以上、本研究の成果を要約すると以下のようである。1.人間の概念を位相空間としてモデル化することが可能である。2.知能の発達,学習を含め、記憶,推論などが、知能の位相空間モデル上で記述可能である。3.概念に関する基本的な性質を公理として設定すると、公理から演繹される諸定理が現実の設計行為をよく説明する。4.位相空間上で記述された設計過程モデルは、そのまま設計を支援する情報処理技術法を生み出すものではないが、システム作成の指導原理として有効...
