This second edition is fully revised and updated to the new ASME Y14.502009 standard. This is the most comprehensive GD&T volume ever written by a single author. Geometric Dimensioning and Tolerancing has the unprecedented ability to cover almost every facet of tolerancing. Time can be a limiting factor in topics to be covered in a workshop or course...but the book has it all! Although based on the rules found in the ASME Y14.5 standard, it also covers topics from other recently published standards by ASME not found in older texts. It includes step-by-step procedures for dimensioning and tolerancing parts and assemblies. It shows how to analyze the tolerances applied using both worst case and statistical analysis. This book demonstrates the connection between the application of functional geometric tolerances and its effect on manufacturability and inspection, stressing optimal ways to achieve a high-quality product at the lowest possible cost to the customer.
