ANSI ASME Y14 43 2011 – Dimensioning and Tolerancing Principles for Gages and Fixtures

This ANSI ASME Y14 43 2011 Standard presents the design practices for dimensioning and tolerancing of gages and fixtures used for the verification of maximum material condition (MMC) size envelopes and virtual condition boundaries generated by geometric tolerances controlled at maximum material condition.

Examples of gages used to inspect workpieces using regardless of feature size (RFS) are shown in Appendix C. These practices focus on the design of receiver-type gages, which collect attribute data when used for the verification of workpieces dimensioned and toleranced in accordance with ASME Y14.5M-1994. For gaging and fixturing principles and practices, see paras. 2 through 6.
