Explanation of Solution
The maximum material condition (MMC) and the least material condition (LMC) is used as a modifier to the size of a feature in the geometric control.
The symbol
The symbol
When the tolerance zone is modified with the (MMC) modifier, it means that the value applies when the feature is produced at its MMC.
The least material condition is applied, when it is too difficult to control the material at its minimum amount.
In case of MMC modification, the amount of deviation from the MMC is added to the specified geometric tolerance
In case of LMC modifier the deviation from LMC is added to the specified geometric tolerance.
For the given case, there is no modifier so the position tolerance zone is equal to the specified position tolerance and it is equal to the
