As the MMC of a feature changes, the size tolerance zone also changes.
MMC
Refers to Maximum Material Condition, the state where a part contains the maximum amount of material within the specified limits, important in geometric dimensioning and tolerancing.
Size Tolerance
The allowable deviations in dimensions defining the limits within which a part must be manufactured to ensure fit and function.
- Understand the impact of maximum material condition (MMC) and least material condition (LMC) on feature control.

Final Answer :
True
Explanation :
As the MMC of a feature increases, the size tolerance zone decreases, and vice versa. This is because the feature has a higher probability of being at the maximum material condition, which means it can be larger than the nominal size. Therefore, the tolerance zone needs to be smaller to accommodate this possibility. Conversely, as the MMC decreases, the feature has a higher probability of being at the minimum material condition, which means it can be smaller than the nominal size. In this case, the tolerance zone needs to be larger to ensure the feature is still within the acceptable limit.
