Lowell W. Foster, expert on geometric dimensioning and tolerancing (GD&T) and chairman of the U.S. National and ISO standards committees, updates his bestselling book to give readers the definitive guide to the new ANSI standard. This up-to-date information will help engineers and designers implement design and product requirements throughout the cycle- from design to manufacture to assembly-using universal standards and practices that result in reduced cost and high-quality products. With the new standard, engineers can state design requirements of ?function and relationship of part? features which they heretofore envisioned, but could not state in the drawing. Available in inch and metric versions.
