We are running a 5 hole pinion carrier on our CMM with 3.5.
I am confused on whether it is allowable for the X,Y coordinates to change from when the location was reported and when the TP (with MMC) was calculated. Shouldn't the center of the feature being measured to the datums be in the same location?
I am also confused on why some of the angles of the holes are reading exactly the same from part to part? (isn't possible with our process) We have tried to turn the part 72 degrees, to keep one of the pinion holes at the 12o'clock position.
I read the TP posts below in the forum and it is still hazy to me.
Thanks for any help
