MMC Calc is a utility to calculate whether or not a measured diameter’s actual position is within tolerance, based on its deviation from design Maximum Material Condition.

This application was designed for people new to Geometric Dimensioning & Tolerancing (GD&T) to help increase their confidence in their own calculations and improve their understanding of GD&T.

MMC Calc is intended to be used by designers, engineers, manufacturing, quality, inspection, and anyone else needing to interpret GD&T in accordance with ASME Y14.5M-1994.
