This book was released on 2013-11-11 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Principal authors: U. Kroszynski, B. Palstr9Sm 1.1 The evolution of concepts and specifications for CAD data exchange The CAD/CAM community has witnessed, during the last decade, the appearance of several specifications as well as proposals for standards which either attempt to cover wider areas or to be more reliable and stable than the others. With the rapid evolution of both hardware and software, the capabilities offered by CAD systems and CAD based application systems are far more advanced than they were only ten years ago, even when they are now based on micro-computers or personal comput ers. The situation with standards, however, is not and cannot be so. In order to be reliable and accepted by a wide community of both vendors and users, a standard has to be sta ble. This implies a life span of at least a decade. This also implies that the standard has to be general and flexible enough to accommodate present as well as expected future developments. 1.1.1 IGES The initial development of concepts for CAD data exchange is strongly influenced by the US Integrated Computer Aided Manufacturing (ICAM) programme, that dealt with the development of methods for data exchange. In September 1979, a subgroup was estab lished with participation of the National Bureau of Standards, the General Electric Com pany, and the Boeing Company. The result of this effort was the Initial Graphics Exchange Specification (IGES) that was published as a NBS report [61] in 1980.
Book Synopsis Solid Modelling and CAD Systems by : Ian Stroud
Download or read book Solid Modelling and CAD Systems written by Ian Stroud and published by Springer Science & Business Media. This book was released on 2011-05-02 with total page 689 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solid Modelling and CAD Systems gives users an insight into the methods and problems associated with CAD systems. It acts as a bridge between users who learn interfaces without understanding how they work and developers who create systems without understanding the needs of the users. The main feature of Solid Modelling and CAD Systems is a logical analysis of the techniques and basic solid modelling methods used in modern CAD systems. The book goes on to describe, among other subjects: two-dimensional shape definition methods, the command interface and graphics, databases and data exchange, early-phase design, and command files and command structures. Reading Solid Modelling and CAD Systems will help users understand the limitations of the techniques they are using and will enable practitioners to use CAD systems more efficiently. It is a valuable tool for designers, as well as for advanced undergraduate and postgraduate students. The exercises it contains allow readers to try out different aspects of the subject matter and the book also includes projects that can be used for teaching purposes.

This book was released on 2012-12-06 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a result of the lectures and discussions during the conference "Theory and Practice of Geometric Modeling". The event has been organized by the Wilhelm-Schickard-Institut fiir Informatik, Universitat Tiibingen and took place at the Heinrich-Fabri-Institut in Blaubeuren from October 3 to 7, 1988. The conference brought together leading experts from academic and industrial research institutions, CAD system developers and experien ced users to exchange their ideas and to discuss new concepts and future directions in geometric modeling. The main intention has been to bridge the gap between theoretical results, performance of existing CAD systems and the real problems of users. The contents is structured in five parts: A Algorithmic Aspects B Surface Intersection, Blending, Ray Tracing C Geometric Tools D Different Representation Schemes in Solid Modeling E Product Modeling in High Level Specifications The material presented in this book reflects the current state of the art in geometric modeling and should therefore be of interest not only to university and industry researchers, but also to system developers and practitioners who wish to keep up to date on recent advances and new concepts in this rapidly expanding field. The editors express their sincere appreciation to the contributing authors, and to the members of the program committee, W. Boehm, J. Hoschek, A. Massabo, H. Nowacki, M. Pratt, J. Rossignac, T. Sederberg and W. Tiller, for their close cooperation and their time and effort that made the conference and this book a success.
Book Synopsis Advanced Modelling for CAD/CAM Systems by : Hans Grabowski
Download or read book Advanced Modelling for CAD/CAM Systems written by Hans Grabowski and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reiner Anderl The Advanced Modelling part of the CAD*I project aimed at the development of a new generation of modelling techniques as a basic functionality of future CAD/CAM systems. The methodology and concepts for advanced modelling techniques, their availability in the communication interface of a CAD/CAM system and their influence on internal interfaces in the software architecture of a CAD/CAM system are fundamental results of advanced modelling work. These results form the basis for the development of a new generation of CAD/CAM systems which are called product modelling systems. CAD/CAM systems today mainly support the geometric description of a technical part or its description as a technical drawing. Advanced geometric modelling capabilities deal with parametric design functions embedded into CAD/CAM systems. However, development strategies for future CAD/CAM systems are directed toward the following: 1. The development of product modelling systems and 2. the development of integrated systems based on CAD, CAP (Computer Aided Planning), CAM and other CIM (Computer Integrated Manu facturing) functionalities.

This book was released on 2012-12-06 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: ESPRIT Project 322, "CAD Interfaces", has been established to define the most important interfaces in CAD/CAM systems for data exchange, data base, finite element analysis, experimental analysis, and advanced modeling. The definitions of these interfaces are being elaborated in harmony with international standardization efforts in this field. One principal goal of the project is to develop techniques for the exchange of CAD information between CAD systems, and from the CAD domain to CAA (Computer Aided Analysis) and CAM (Computer Aided Manufacturing). This volume presents a proposal for a neutral file format for CAD data: curves, surfaces, and solids. The specification is based on a reference schema for CAD data bases and is defined informally with respect to its semantics and formally with respect to its syntax. This volume is a revised edition of "Specification of a CAD*I Neutral File for Solids" Version 3.2. The revision reflects the enhancements which result from the implementation of communication processors in eight different CAD systems and from the practical exchange of solid models between these systems. Due to the close interaction between the CAD*I project and the coming-up international standard STEP this specification also serves as an introduction to the geometry model that will be included in the future international standard.
Book Synopsis Digital Products by : C. Werner Dankwort
Download or read book Digital Products written by C. Werner Dankwort and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: In addition to the classical needs, competition on the global market requires from industry product innovations: quality, time to market, reduction of costs (Q,T,C). The modern process networks of product development and manufacturing passing the borders of countries and including several companies could not work without an extensive use of information technology. This is going far beyond the former idea of Computer Aided Design. Thus the 3'd Workshop on Current CAx-Problems did not focus on functionalities or methods aiding design like in the first two workshops but on "Digital Products - Living Data is the Future": problems of the virtual simulation of the entire industrial process, starting with the development of a product and covering the complete life cycle. The workshop aimed at bringing together the three groups: industry (mainly automotive manufacturers), system suppliers, and fundamental research. During the workshop, communication between these three groups had to be intensified, and especially also among competing companies of the same branch to pave the way for concerted actions, which are essential for all in the future.

Book Synopsis Computer Applications in Production and Engineering by : Frank Plonka
Download or read book Computer Applications in Production and Engineering written by Frank Plonka and published by Springer. This book was released on 2013-06-05 with total page 750 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the latter half of the 20th century, forces have conspired to make the human community, at last, global. The easing of tensions between major nations, the expansion of trade to worldwide markets, widespread travel and cultural exchange, pervasive high-speed communications and automation, the explosion of knowledge, the streamlining of business, and the adoption of flexible methods have changed the face of manufacturing itself, and of research and education in manufacturing. The acceptance of the continuous improvement process as a means for organizations to respond quickly and effectively to swings in the global market has led to the demand for individuals educated in a broad range of cultural, organizational, and technical fields and capable of absorbing and adapting required knowledge and training throughout their careers. No longer will manufacturing research and education focus on an industrial sector or follow a national trend, but rather will aim at enabling international teams of companies to cooperate in rapidly designing, prototyping, and manufacturing products. The successful enterprise of the 21st century will be characterized by an organizational structure that efficiently responds to customer demands and changing global circumstances, a corporate culture that empowers employees at all levels and encourages constant communication among related groups, and a technological infrastructure that fully supports process improvement and integration. In changing itself to keep abreast of the broader transformation in manufacturing, the enterprise must look first at its organization and culture, and thereafter at supporting technologies.

Download or read book Advances in Computer Graphics V written by Werner Purgathofer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book collects together several of the tutorials held at EUROGRAPHICS'89 in Hamburg. The conference was held under the motto "Integration, Visualisation, Interaction" and the tutorials reflect the conference theme. The Springer series EurographicSeminars with the volumes "Advances in Computer Graphics" regularly provides a professional update on current mainstream topics in the field. These publications give readers the opportunity to inform themselves thoroughly on the topics covered. The success of the series is mainly based on the expertise of the contributing authors, who are recognized professionals in their field. Starting out with one of the conference's main topics, the chapter "Visualization of Scientific Data" gives an overview of methods for displaying scientific results in an easily surveyable and comprehensible form. It presents algorithms and methods utilized to achieve visualization results in a form adequate for humans. User interfaces for such systems are also explored, and practical conclusions are drawn. The chapter "Color in Computer Graphics" describes the problems of manipulating and matching color in the real world. After some fundamental statements about color models and their relationships, the main emphasis is placed on the problem of objective color specification for computer graphics systems. It is very hard to match colors between devices such as scanners, printers and displays. Some suggestions on the effective use of color for graphics are also made.
