hey there
I was wondering what "UN" means when written after the diameter of the thread cut. is it the same as TPI?
i am trying to find out my Depth of cuts and minor DIA and Chamfer DIA but the #s don't add up to what the autocad diagram has shown here.
i used to calculate this with TPI like a 3/4-10 TPI external internal what have you but now i got 1-16UN or 1.5-16UN in another place where the calculations don't match.
thanks.
