GD&T: The Basics of Geometric Dimensioning and Tolerancing

WebMar 18, 2024 · In simple terms, as a part’s actual size departs from the MMC size, the difference between the actual size and the MMC size is added to the straightness tolerance value. This is known as bonus tolerance. For example, imagine a pin that needs to fit into a hole of a given size at MMC. WebMMC defines the worst case condition of a part that will still guarantee, because it is still within the prescribed tolerances, the assembly between pin (s) and hole (s). When a hole is at its smallest (MMC) and a pin is at its largest condition (also MMC), we can be sure that we will still be able to assemble that part.
