In GD&T, bonus tolerance is a modification of a GD&T tolerance that under certain conditions increases the tolerance, hence the term “bonus”. The secondary datum (commonly Datum B) will always be perfectly perpendicular to Datum A. Check all that apply. LM = (x 2 – x 1 )i + (y 2 – y 1 )j + (z 2 – z 1 )k. However, if you are getting stuck with how to apply or interpret GD&T, be sure to check out our GD&T Training Program. Dimensioning specifications define the nominal, as-modeled, or intended geometry. These are grouped into form tolerance, orientation tolerance, location tolerance, and run-out tolerance, which can be used to indicate all shapes. Maximum Material Condition or for short, MMC, is a feature of size symbol that describes the condition of a feature or part where the maximum amount of material (volume/size) exists within its dimensional tolerance. 94 in 2022.
