I need to measure a dimension to the centerline of a radius, but the radius is 2" and only covers an arc of about 25 degrees. Measured on the optical comparator, the radius is nearly nominal, but on the CMM it measures 2.117". This throws my centerline over .100" out of position. How can I create a centerline from points on the radius using the nominal radius? Can I force PC-DMIS to best fit a 2" radius to points on the surface?
Sean has my agreement also. It is NOT a Pc-dmis thing, or even a cmm thing, its a mathematical issue. Polar coordinates are the best way, from the known radus center. I wish ppl would say its not possible, if I don't know for sure, I just say that, not, "It can't be done with Pc-dmis".
