This book contains selected contributions from the 6th CIRP International Seminar on Computer-Aided Tolerancing, which was held on 22-24 March, 1999, at the University of Twente, Enschede, The Netherlands.
This volume presents the theory and application of consistent tolerancing. Until recently CADCAM systems did not even address the issue of tolerances and focused purely on nominal geometry. Therefore, CAD data was only of limited use for the downstream processes. The latest generation of CADCAM systems incorporates functionality for tolerance specification. However, the lack of...

Design is a fundamental creative human activity. This certainly applies to the design of artefacts, the realisation of which has to meet many constraints and ever raising criteria. The world in which we live today, is enormously influenced by the human race. Over the last century, these artefacts have dramatically changed the living conditions of humans. The present wealth in very large parts of the world, depends on it. All the ideas for better and new artefacts brought forward by humans have gone through the minds of designers, who have turned them into feasible concepts and subsequently...

Can a Baby Be an Enemy? Our world is in a deep, prolonged crisis. The threat of global nuclear war, the chronic condition of local wars, the imperilled environment, and mass star- vation are among the major forms this crisis takes. The dangers of massive overkill, overexploitation of the environment, and overpopulation are well known, but surprisingly little has been said about their potential interac- tions, their bearing upon each other. If there were to be a nuclear confronta- tion between today's superpowers, it might not take place in today's world, but in a far less friendly habitat,...
