With only 90 degrees of arc, how accurate should I expect a corner radius measurement to be using my CMM?
I've got a part with a R .250" +.000/-.003". I get afew that measure within tol, and a few that don't. I'm taking plenty of hits (13), and spread the hits across as much of the arc as I can without getting into the flat (about 85 degrees). Not sure if I believe my results.
What do you guys think?
