I know this issue has been covered in the past, but not to the degree that I'm dealing with.
The engineers here are adamant in using MMC for the true position of a threaded hole. "The MMC of what?" I ask. "The P.D." is their reply.
A typical callout is:
.750-10 UNC-2B
|TP|DIA .010 M|A|B M|C|
Am I missing something? As in, "What is the MMC of a pitch diameter?"
Input appreciated and looked forward to. Thanks.
