9780412447808: Computer-based Design Process

Sinossi

This text explores the use of computer-aided design (CAD) techniques in the solution of mechanical engineering problems. The numerous applications presented, provide the basis for a broad theory covering the creation and application of CAD systems in practice. This work has led to the generation of a more general approach to design theory. The second edition contains two new chapters covering the research and application of constraint modelling theory that arose directly from the work presented in the first edition. The book's general approach covers all aspects of mechanical design ranging from the design and control of assemblies to the remote operation of coordinate measuring machines via a CAD system. This book should be of interest to graduate engineers, designers, postgraduate students and research engineers.

Recensione

`...the book is well structured in its presentation and coverage of design theory. The holistic approach to design and the principles of constraint modelling are explained clearly and unambiguously...The book is well laid out and easy to assimilate (owing to its structured content) with a good index...the book is a worthwhile text, if only for its coverage of design theory and CAD process'- Int. Journal of Production Research
