I am wondering how to interpret some results that I have. Both the bore and the OD are out of round. I was very surprised though when it showed over .020". I had the next one report out the form deviation for each feature. My question is, with the results of the form deviation would this part be considered to be .020" or .006" out of round? I am thinking that the Min/Max of the form deviation is individual points and the RMS would be what I am after. If that is the case, why under the feature report, does the circularity report the total difference between the Min/Max?
