1. Like the title says, why does adding pitch when checking threads matter?
2. Does it?
3. If you are checking a thread as a cylinder, how does adding the pitch affect the measurements?
4. If you are checking the "cylinder" using least squares, and it's averaging out the points anyways, does adding pitch calculate position more accurately?
(i might have asked the same question a few different ways!)
using pitch 'ensures' that the probe always hits on the same portion of the thread, be it the very peak or somewhere else, but it is the same relative place on the thread. No pitch and opposing hits will be (for example) on the peak and in the ditch. not good for size or location.
