How would one calculate pitch diameter for external threads on a CMM and verify that the results are correct. I need to check some pretty large acme threads im not too sure about the nominal dimensions.
dont use the cmm to verify pitch diameter...unless the threads are huge and flat and you have a way to insure the probe hits the correct spot on the start of the thread every time....almost impossible.
