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. Its advantages are uniformity in design practice, ensured interchangeability, consistent interpretation, and maximum tolerance allocation. 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. 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.
