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?
I work 95% off-line. So using the jog box and taking extra hits is somewhat out of the questions unless I use auto vector points. ctrl+e and recapture all seem to be on-line programming. Is there another procedure for off-line programming. I tried using an auto circle with 30 hits on 2 small radius, then I also did a scan with 30 hits that were then created into vector points. I created a circle out of them. These were two different radius, one on top, one on bottom. Both types came out extremely lousy. Reporting out individual points still doesn't give a true position reporting. Is what you are saying is that it is very unlikely that I will ever be able to create a circle out of these hits and get accurate true position results.
No, that not what I said at all
these steps were given to me from a B&S AE and work fine ONLINE
you could try to modify them for use offline and test it online
The true pos could be obtained in the step #4
diameter in step #9
