X! o  u1 @, k, TOfcourse yes.The master ball has dia of 20mm but i have input its value in the software according to the certificate that is 20.002mm.I think i am right.am i?i am measuring ring gage dia with the probe of length more than 3 inches with ball dia 6 mm.In small ring gages , the difference in dias are less but a i move to bigger gages , the difference goes to 10 microns.why its varying gage to gage of different sizes?
Anotehr thing when i auto calibrated this probe , the software has calculated its dia as 5.661,5.471,5.767,5.787 against 6mm .why the measured dia is so small.i think this thing is introducing error in my readings from this probe?Any suggestions plz.

另外，當我自動校準測頭的時候,對于6豪米探針軟件校準直徑值為5.661,5.471,5.767,5.787。為什么測量直徑如此小,我猜是不是從測頭中引入的誤差到測量結果中.那位能給點建議

Are you sure the ring gages are round?

你確定環(huán)規(guī)是是圓的嗎？

When you say 10 microns, you mean the difference between the actual ring gage diameter and the diameter the cmm measures the ring gage?
This is basically due to the fact that the probe is calibrated on a 3d sphere and is averaged out based on that. If you are more concerned about 2d

Once you have a program for probe calibration then you should do some testing. Calibrate the stylus and inspect the ring gage several times. Re-position the

ring gage between runs. You may want to re-clean it between runs but be careful not to affect the temperature. Then, repeat this whole process several times
