![]() In a Shaft/pin, MMC = Maximum allowed diameter according to the tolerance.Ĭombining true position with MMC is very powerful.In a hole/bore, MMC = Minimum allowed diameter according to the tolerance.Maximum Material Condition (MMC) is a GD&T symbol indicating the maximum or minimum allowed tolerance of a feature where it has the maximum amount of material (volume/size). ![]() True Position with MMC (Maximum Material Condition). Datum: The datum plane (or axis) from which the position is measured.(True position is typically paired with MMC ) Material condition: If a material condition is indicated, you can add a Bonus tolerance to the allowed deviation (3).True Position Toleance: The maximum allowed deviation from the theoretical position.If the feature is a slot, then this symbol will be omitted. In such a case, the position deviation is multiplied by two. True position is most often used on holes and, therefore, will include the diameter symbol. ![]()
