Need a little help figuring out MMC on some holes and whether they pass or fail. As an example, Datum A is the bottom, B and C are two sides,so i set up a coordinate system between all three. Hole is basic dimension 19.738 in one direction and the other is basic dimension 30.833, hole diameter is supposed to be .438 +.006 / -.001, True Position with .007 MMC to Datums A,B,C. The hole diameter i measure is .440 and basic dimensions are 19.7409 and 30.837. I get stuck on trying to manually figure out weather it passes or not on the position. I know we get an extra bonus tolerance but on how to calculate it is where i get stuck. Can someone help? Thanks ahead to all those that can.
