Composite Profile Tolerance

Post by robyc01 » Mon Aug 18, 2014 10:28 am

I am trying to deal with a part that has a composite profile tolerance and I have no idea if CMM Manager can handle this or not. Any ideas?

I believe you can treat it like a true profile and a form only profile. One can be reported as CAD synced to measured A|B|C and then other reported just as best fit (no need to lock any of the best-fit axis since there is no follow up datum in the second call out)

I cannot report composite position on a cloud or surface, only on circles, cylinders, cones, spheres, and slots.

Ya right.... So refer to the previous response. Report Cloud to CAD twice. Once with best fit option and then again without. Sorry for the confusion.

I had to do some reading up on composite profile tolerances, and now have a better understanding. Just as you said John K, measure the first to A-B-C and then the second one is form only so a bestfit would work. Thank You.
