Hi all,

Hoping someone can clarify, measuring a ring gauge on our Zeiss CMM, if I measure in the traditional manner, moving the probe head around the diameter, I get a different result compared to keeping the probe head fixed and turning the rotary table! Myself and my colleagues all believe that that we should be getting the same result? The 2 circles are identical in terms of number of points, Z-height, alignment and filtering etc, the only difference is which part moves, the probe head or turn table.
