Good morning everybody...

I am hoping that you can help me understand a couple of things about the calibration results window. First of all, I don't understand where the CMM is getting the X,Y, and Z numbers from. My actuals are sometimes not even close to what is reporting as the theoretical values. I'll have an X theoretical of 0.000 and an actual sometimes of 10mm or more. I don't understand why this is. I've even seen a difference of 20mm at times.

The next thing is the actual diameter of my tip. I've attached an image of my last calibration which is on a 1.5mm probe tip and the results are 1.4746mm. This calibration was done at 80% movespeed and 2% touchspeed. When I decrease it to 20% movespeed and 1% touchspeed I see almost identical results. I measure this tip with a micrometer and it comes out perfect. 1.5mm. I don't understand why the CMM is reporting the diamter at almost .025mm off. Any insight and wisdom from you guys and gals would be tremendously appreciated since I am being asked to explain this difference to my bosses. Thanks in advance!
