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.



1. Introduction.

Why Use Geometric Dimensioning and Tolerancing? What is Geometric Dimensioning and Tolerancing? When Should Geometric Dimensioning and Tolerancing Be Used? Geometric Characteristics and Symbols. Using Symbols. Maximum Material Condition Principle. Regardless of Feature Size. Least Material Condition Principle. Basic and Datum. Symbolic Method of Stating a Basic or Theoretical Exact Value - Recommended. Datums and Datum Feature Symbol. Feature and Feature Control Frame. Combined Feature Control Frame and Datum Feature Symbol. Reference to Datum. Geometric Characteristics - Form, Orientation, Profile, Runout, and Locational Tolerance - Other Symbols and Terms. Geometric Characteristics, Symbols, and Terms. General Rules. Virtual Condition (MMC). Virtual Condition (LMC).

Geo-Metrics III is an extensively revised edition of the most respected and widely-read book on geometric dimensioning and tolerancing, the technical drawing language for designing and manufacturing component parts of a mechanical product. Completely up to date, this new edition takes its reference from the content of the latest ANSI/ASME Y14.5M standard as well as harmonizing with the principles of related ISO international standards. It is also supportive of the ISO 9000 series of international standards policies and directives.

Geo-Metrics III is an indispensable guide and reference for anyone involved in engineering design, drafting, manufacturing, quality, and verification of product. In it you will find the state-of-the-art in the principles and techniques of engineering design specification, with comprehensive coverage of such topics as:

  • Geometric characteristics and symbols

  • Datums and their application

  • Tolerances of form, orientation, profile, runout, location, and their application

  • The material condition principles MMC,LMC, and RFS, and their application

...and much more.

This new edition focuses on important aspects of the latest standards and the ability to represent "function and relationship" of part feature requirements which engineers have envisioned but cannot explicitly state in drawings. In addition, Geo-Metrics III emphasizes the need for recognition of the emerging international standards which are so important in present-day global communication.

The author's experience and insight, evident throughout the book, will lead you to a deeper understanding of the rationale behind the standards, enabling you to apply them more effectively in your work. The principles in Geo-Metrics III, combining the latest standards and techniques of modernized engineering product specification, facilitate clear communication through the process of design, manufacturing, assembly, and verification while promoting reduced costs and higher quality.

For those companies that have not yet adopted the latest ANSI standards, these reference guides are still available:
