WebMaximum Material Condition (MMC) refers to a feature-of-size that contains the greatest amount of material, yet remains within its tolerance zone. Some examples of MMC include: – Smallest hole diameter. – Largest pin diameter. It is the smallest hole diameter because a larger hole removes material, hence the smallest diameter provides for ... WebMar 18, 2024 · Straightness tolerance is a 2-dimensional GD&T callout that controls the straightness of part features. No axis can be perfectly straight. The goal is to ensure it is straight enough for the application. This callout …

Understanding Geometric Dimensioning and Tolerancing
Design Intent: Easier Assembly (Implied: Less Location Accuracy) Worst Case Condition for Assembly: Maximum material condition The design intent of the maximum material modifier being easy and guaranteed assembly, we don’t care if the mating pin wiggles around a bit after assembly. So we … See more Figure 2. Part with Least Material Modifier: As the designed fit gets tighter (Pin tolerance decreased with respect to the one in Figure 1), the least material modifier becomes more appropriate. Design Intent: More … See more Figure 3. Part with Regardless of Feature Size Condition: As the location accuracy is of the utmost importance, there is no relationship between the hole size and the position tolerance (Pin tolerance indicates a press fit and no … See more Hence, we could summarize the relationship between hole size and relative bonus tolerance as follows: 1. MMC: As the hole gets larger, bonus tolerance increases, 2. LMC: As the hole gets smaller, bonus … See more WebHere, the location will be measured related to datum B and C. Next to the tolerance or a datum feature is an optional encircled letter, the feature modifier. The following possibilities can occur: M means that the … WebMaximum Material Condition (MMC) The maximum material condition is used when designing two mating parts.
