Product Modelling For Computer Integrated Design And Manufacture

This state-of-the-art text explores developments in geometric modeling, product modeling and their applications. In particular, it looks at the means by which product geometry emerges from the conceptual stages of design, and the use of geometric reasoning for applications downstream of design, including manufacture ands assembly. Much existing design research is either totally geometry based or totally non-geometric, and the interface between the two areas is of intense interest to industry, as well as being crucial for the successful development of integrated systems for design and manufacture. This interface is currently not well understood and the book makes a significant contribution towards its understanding. This book is essential reading for technical managers and research and development engineers.

This book presents recent advances in the integration and the optimization of product design and manufacturing systems. The book is divided into 3 chapters corresponding to the following three main topics : - optimization of product design process (mechanical design process, mass customization, modeling the product representation, computer support for engineering design, support systems for tolerancing, simulation and optimization tools for structures and for mechanisms and robots), -optimization of manufacturing systems (multi-criteria optimization and fuzzy volumes, tooth path generation, machine-tools behavior, surface integrity and precision, process simulation), - methodological aspects of integrated design and manufacturing (solid modeling, collaborative tools and knowledge formalization, integrating product and process design and innovation, robust and reliable design, multi-agent approach in VR environment). The present book is of interest to engineers, researchers, academic staff, and postgraduate students interested in integrated design and manufacturing in mechanical engineering.

Design and manufacturing-preparation activities can be regarded as information processing activities that, starting from the original concept of the product and the use of product models, generate detailed manufacturing control information and the framework which describes all the necessary information about the product and its processing. In order to achieve a higher level of automation for design and manufacturing processes, it is essential to analyse engineering information as transferred to and manipulated among related activities. It is also vitally important to prepare the framework which is to capture the information systematically; this is known as the engineering knowledge. It includes basic information such as dimensions, tolerances, assembling, mechanics, etc., and also expert knowledge which strongly depends on the respective engineering and product domains. This book examines the methods used in the representation and manipulation of this engineering knowledge, as well as in the generation and manipulation of product models.

Integrated Design of a Product Family and Its Assembly System presents an integrated approach for the design of a product family and its assembly system, whose main principles consider the product family as a fictitious unique product for which the assembly system is to be devised. It imposes assembly and operation constraints as late as possible in the design process to get liberties in the system design, and adapts the product family at each design stage to integrate the new constraints related to the successive design choices. Integrated Design of a Product Family and Its Assembly System is an important, must-have book for researchers and Ph.D. students in Computer-Integrated Manufacturing, Mechanical Engineering, and Manufacturing, as well as practitioners in the Design, Planning and Production departments in the manufacturing industry. Integrated Design of a Product Family and Its Assembly System is also suitable for use as a textbook in courses such as Computer-Aided Design, Concurrent Engineering, Design for Assembly, Process Planning, and Integrated Design.

Methods presented involve the use of simulation and modeling tools and virtual workstations in conjunction with a design environment. This allows a diverse group of researchers, manufacturers, and suppliers to work within a comprehensive network of shared knowledge. The design environment consists of engineering workstations and servers and a suite of simulation, quantitative, computational, analytical, qualitative and experimental tools. Such a design environment will allow the effective and efficient integration of complete product design, manufacturing process design, and customer satisfaction predictions. This volume enables the reader to create an integrated concurrent engineering design and analysis infrastructure through the use of virtual workstations and servers; provide remote, instant sharing of engineering data and resources for the development of a product, system, mechanism, part, business and/or process, and develop applications fully compatible with international CAD/CAM/CAE standards for product representation and modeling.
