Description / Abstract:

This 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 MMC, and datum features controlled at maximum material boundary (MMB). Some examples of gages and fixtures used to inspect workpieces using regardless of feature size (RFS) and regardless of material boundary (RMB) are shown in Nonmandatory Appendix C.

Most of these practices focus on the design of receivertype gages that collect attribute data when used for the verification of workpieces dimensioned and toleranced in accordance with ASME Y14.5-2009. Some examples of fixturing workpieces for the collection of variables data are shown. These practices represent examples of product definitions allowed by ASME Y14.5. Since ASME Y14.5 is not a gaging standard, ASME Y14.43 shows the practical embodiment of the theory displayed in ASME Y14.5 by illustrating how the workpieces can be fixtured and gaged for tolerance verification.

For gaging and fixturing principles and practices, see sections 4 through 8 and Mandatory Appendices I and II.
