True Position MMC


Recommended Posts

Could someone please review the formula along with the screen grabs below regarding my calculation for hole position with max material condition applied. Would be interested to see someone else's approach to measuring this on Calypso.

Thank you greatly

That's not how that works. Datum A is MOBILITY. The pattern would be evaluated as a set, smallest modifier probably governs. Then the SET can translate and rotate within the Datum A virtual condition boundary. They are simultaneous requirements. How long is Datum A bore ? and is there a seperate perpendicularity requirement to face ?
