Having recently learned about using the pitch option I have a question. In the Auto Circle window entering the pitch of a thread causes the probe to take hits in a progressive fashion to follow the thread.
I have a right hand thread that is oriented such that I must measure it with tip A90B90. The vector of the circle is 0,-1,0. When I entered a positive pitch the hits were taken by moving the tip +Y in between hits. This was the wrong direction. I entered a negative pitch and it moved correctly.
Does the sign (+ or -) have to match the vector of the hole?
With this particular thread it was not a problem as it is external and I can see the probe moving properly. Coming up I have a small (8-32) internal thread. I don't think I will be able to tell if it is moving in the correct direction.
Any suggestions?
