MMC & LMC modifiers and CMM measuring techinques like diameter least squares and circularity or minimum/maximim diameter.

#1
Dear all,

is there a relation about new dimensions modifiers like MMC and LMC and measurements techniques?
For example, if I've to verify an hole with the MMC symbol on a roundness tolerance, which kind of measurement strategy has to be used for?
Least squares and circularity or minimum diameter?

Hi Marco, a screen shot or drawing will help insure we are on the right path...please share...

The request is generic, however the following picture can be a good example, referring to quote 1 and 60: (is right also then, to have linear dimensions with only value and tolerance, and no specifications about strategy to verify it?)
