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 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.
