[Ma...] Posted Friday at 12:04 PM Share Posted Friday at 12:04 PM I was trying to measure a ring gage to correlate with our ULM system when I noticed that the dimensions were way different. Ring gage should have measured 2.99996 and CMM is measuring it at 3.00046 a difference of .0005. Have also checked gage blocks and getting error within .0005 - .00076. Machine is a Zeiss Prismo with a Vast Gold head. I have verified that the correct head is selected, the calibration sphere dimensions are accurate, requalified Master, and probe used for inspection has been calibrated as well. What am I missing? Is there something else that could be causing this error? Link to comment Share on other sites More sharing options...
