Mmc

Geoff P
Can’t believe most inspectors and especially engineers don’t know this!

On a hole diameter MMC = Actual measured hole size minus the smallest allowable size which is the MMC condition… max material.

So for TP .5 on a 10.0 +/- .5 hole that measures 10.1
You get .6 Bonus (actual size 10.1 minus the smallest size 9.5 = .6) this .6 extra tolerance is then added to the given .5 TP tolerance for a grand total of 1.1 tolerance.

For a solid pin or outside cylinder it’s outside diameter, same concept. Largest allowable size minus the actual = Bonus Tolerance.

BONUS TOLERANCE =
DIFFERENCE BETWEEN MMC SIZE AND ACTUAL SIZE! ADDED TO GIVEN TP TOLERANCE IN THE FEATURE CONTROL FRAME.​

  • My buddy was buying a car last week. He got into an argument with the Finance Manager (who had an MBA on the wall). They tried to pull the ole' switcheroo with the interest rate at the last minute..guy got p!ssed and during the incident yelled "he doesn't believe in math or calculators!". Must be related to your co-worker Rolling eyesRolling eyesRolling eyes

    My coworker IS the calculator. It wouldn't surprise me if he wrote a letter to Texas Instruments telling them that their calculators are wrong.
