The general principles of geometric dimensioning and tolerancing are described, helping users define precision-related specifications unambiguously and consistently with the constraints of the manufacturing and inspection processes. The book describes the international standardization in this field while also indicating how it differs from the American Standard ASME Y14.5M. Geometrical Dimensioning and Tolerancing for Design, Manufacturing and Inspection: A Handbook for Geometrical Product Specification Using ISO and ASME Standards, Third Edition presents the state-of-the art in geometrical dimensioning and tolerancing.
Provides the information needed to become conversant in the techniques of GD&T and how to smoothly integrate this knowledge into engineering design and modern inspection systems. Includes over one hundred drawings that illustrate concepts under discussion. Reinforces the explanations with end-of-chapter self evaluation exercises (the answers to all questions and problems are contained in the back of the book).
Uses a building-block approach with examples (some dimensioned and toleranced in inches and some in millimeters) to illustrate each concept. Deductively organized, this book is a complete on-the-job reference that provides a thorough understanding to the complex ASME Y14.5M-1994 Dimensioning and Tolerancing standard. With GD&T, design requirements can be specified explicitly and the latest gaging techniques can be accommodated, contributing to higher productivity and less rework and scrap.
Its advantages are uniformity in design practice, ensured interchangeability, consistent interpretation, and maximum tolerance allocation. Geometric dimensioning and tolerancing (GD&T) has become accepted around the world as the international symbolic language that allows engineers and machinists to use engineering drawings to communicate from the design stage through manufacturing and inspection.
