The Maximum Material Condition (MMC) Calculator is a valuable tool used in engineering and manufacturing to determine the maximum allowable size of a feature within specified tolerances. It calculates the MMC by adding the Basic Size of the feature to the Allowance, providing a crucial value for ensuring the functionality and quality of manufactured parts.
Formula of Maximum Material Condition Calculator
The formula for calculating Maximum Material Condition (MMC) is straightforward:
MMC = Basic Size + Allowance
- MMC is the Maximum Material Condition.
- Basic Size is the nominal or target size of the feature.
- Allowance is the allowance specified in the tolerance zone, usually a positive value for holes and a negative value for shafts.
General Terms Table
|Nominal or target size of the feature.
|Specified allowance in the tolerance zone, positive for holes and negative for shafts.
|Range of acceptable variation in size or dimension for a feature.
|Maximum Material Condition (MMC)
|The largest allowable size of a feature within specified tolerances.
Example of Maximum Material Condition Calculator
Suppose we have a shaft with a Basic Size of 50 mm and an Allowance of -0.05 mm. Using the MMC Calculator:
MMC = 50 mm + (-0.05 mm) = 49.95 mm
So, the Maximum Material Condition for this shaft would be 49.95 mm.
