Theory and practice of tolerances are very important for designing and manufacturing engineering artefacts on a rational basis. The introduction of computer-aided methods has led to new developments, which are presented in this book. This work comprises a collection of contributions covering key technologies including: functional tolerance description; formal modeling of tolerancing; modeling of geometrical errors and variations; statistical tolerancing; computer support systems for tolerancing.
