Web26 feb. 2008 · In order for you to measure this you need the minor diameter in order to calculate MMC, BUT if you do not measure exactly on the crest of the minor diameter then any bonus may be questioned. I have used the locators in the past (before PC-DMIS), but now I hit on the threads.

WebSo, you state that your bonus tolerance is "0.1", this indicates to me that the hole was manufactured 0.1 larger than the allowed MMC for the hole. Therefore; your acceptable position tolerance is equal to 0.25 + 0.1 = Diameter 0.35. Assuming datum A is a feature which is perpendicular to the hole feature, then you have a cylindrical shaped ... Web27 jul. 2009 · When actual size of the feature varies from MMC then we will have bonus tolerance.
