Hi,

I'm trying to calculate MMC for one dimension, but honestly speaking I forgot how to do it.

Our CMM routine is not calculating automatically, and we have few true position and profiles out of spec, but I see that MMC is not being considered, even though the drawing calls for it.

This is the example:

Female hole

3.4 +/- 0.1 MM Actual result is 3.42

TP 0.2m A Bm

And datum B is another female hole:

6.7 +0.2 -0 MM Actual result is 6.92

TP 0.4m A Bm

Basically I forgot how to do the calculation in paper . I know that these are simple operations.

To clarify, I'm looking how to calculate bonus tolerance in TP's.

I appreciate your support.

Thank you.
