Major product and production characteristics which are affected by tolerances are product quality and cost. In order to optimally compromise the conflicting requirements of quality and cost, it is essential to take into account of the total product life cycle throughout product planning, design, manufacturing, maintenance and recycling.
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.
