Introduction or Preface
This text has been prepared to promote worldwide use of geometric dimensioning and tolerancing and to up-grade knowledge on the subject. Its titleGeo-Metrics IIIattempts to represent and encourage the giant stride being taken by United States industry in its transition toward greater use of national and international standards on this subject. This text also aspires to be of value to all users worldwide as a catalyst for better understanding and to improve the state of the art. This text is a revised and expanded version of its predecessorGeo-Metrics II.Another major objective of this text is to promote and encourage use of the principles involved as an effective engineering, production, and quality-control language or tool which can provide economic and technical advantages.To further the foregoing objectives, this text is therefore presented in a format suitable for use as a teaching mechanism, both for the classroom and in-industry situations, as well as for providing a daily ready reference for engineering or production work.Geo-Metrics IIIis dedicated to the promoting of standardization of engineering drawing techniques in support of the American National Standard "Dimensioning and Tolerancing," ANSIASME Y14.5M-1994. This text is also dedicated to furthering worldwide efforts through the International Standards Organization (ISO) and its standards and programs (e.g., ISO/TCIO/SC5 "Geometrical Dimensioning and Tolerancing"). To this end, this text attempts to extend the principles of the current standards both national and international, into a harmonization of practices that reflect the imminent international state-of-the-art. See the Introduction of this text for further details on the harmonization of concepts and standards on this subject.The data contained in this book must be considered advisory and are to be used at the discretion of the reader. As a new feature of this book, "author advisory" comments are inserted at various places in the text. These offer "rules of thumb," helpful hints, suggestions, etc., as based upon the author's experience and assist the reader in determining options and making choices. All such comments adhere within the spirit and sense of the governing standards while refining the content of those standards.The author wishes to express his gratitude to his many colleagues and professional friends in this field of endeavor around the world who also have made contributions to the state of the art. He also wishes to give credit to the reference documents listed and to those responsible for them.Finally, the author wishes to express particular gratitude to his wife, Marion, daughter, Janette, and son, John, for their assistance, patience, and understanding for enduring the often untimely sacrifices of family together time.

Summaries
Back Cover Copy
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: Geo-Metrics II: The Application of Geometric Tolerancing Techniques (Using the Customary Inch System), Revised 1986 Edition ISBN 0-201-11527-1 * Paperback * 336 pages * (c)1986 Geo-Metrics: The Metric Application of Geometric Tolerancing Techniques, Revised 1986 Edition ISBN 0-201-11526-3 * Paperback * 336 pages * (c)1986 Pocket guide versions of Geo-Metrics II and Geo-Metrics III are also available. These handy guides increase the usability of this information on the manufacturing floor and serve as a quick reference to ANSI standards. These pocket guides are easy to carry and contain the crux of geometrics.

Long Description
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.

Main Description
With Geo-Metrics III, Lowell Foster updates his classic guide to geometric dimensioning and tolerancing (GD&T). Involved in the development of both U.S. National and ISO standards, the author presents the most up-to-date information available about the present and emerging standards that will harmonize national and international practices and be supportive of the ISO 9000 series of standards. Now you can access this important information, be privy to new developments in the field, and gain the competitive edge by getting up to speed on this new dimension of GD&T applications.
