Anybody have experience checking true pos. of a hole with a spiral thread? According to the shop manager here, one side of the threads differs from the other side. When I input my minor diameter, the hole size shows up much larger. I think the problem could be occuring because I am using the pitch option with the Auto Circle Feature. The shop is also thinking that since the hole size is coming up larger than it actually is, and I am getting the true position bad, that I shouldn't be using the pitch option on a spiral thread. Since the form of the thread is different, they think the form of the hole is off, and that is screwing up the location. Any ideas?
All help is greatly appreciated!
