I attached a very crude sketch of my situation:
Total Runout of datum -B- (Planar face) to datum -A- (Minor O.D.). CMM measurements are inconsistent in both PC-DMIS and Zeiss Calypso.
Nobody in the building can show me how to verify on a surface plate....
The length of -A- is very small compared to it's diameter (about .25" vs 8.5") so locating on -A- is difficult. Not to mention part is very lightweight aluminum.
Any suggestions on CMM/Plate setup measurements?
I have CMM doing basic level to -B-, rotate to line formed by holes on -B-, origin XY on -A-, Z on -B-.
