Are you sure the ring gages are round?
You can verify by printing out a plot of the roundness then rotating the ring gage and running again. If the shape of the plot rotates with the ring gage
then the ring gage is out of round.

# U1 V; F, {% C7 rGoldenPine. Don't worry about the probe calibrating smaller than its real diameter, that's normal and understandable. What you do need to worry about is the variation of the "calibrated" diameters of your probe stylus which are HUGE. I've just checked the two 6mm probe on my machine and the variations are from 5.987 - 5.991 for 14 probe orientations (swivel length 93mm) and 5.913-5.922 for 17 orientations (swivel length 138mm).

Obviously before probe calibration, the cal sphere and Styli should be clean and free from debree, which would effect the results of the calibration.
When i first joined my company a simple wipe with the fingers or peice of rag had sufficed.
However I noticed while inpecting the styli under a microscope, the ruby styli was littered with debree such as small peices of aluminium, cast iron, small hairs etc.
( D; _9 }+ D* s6 U& [* z8 j* RBecause of this I started to clean the styli and cal sphere with solvent based liquids such as Geneclean, SBP2 & currently Amberklene.
Any thoughts on my process, is a solvent likley to have a detremental effect on the ruby,any alternatives, what do you do at your company?
