I have used edgecam a lot for threadmilling,
NPT too, but in most cases i use full-profile threadmills, then i don't have to bother about the taper,
I just drill the hole, and the threadmill does the taper itself,
but i allways go to full depth at once, and make several radial cuts, i do this by copying the treadmill cycle and change the major diameter, thread depth is allways set to 0,01mm to make sure the major diameter gets correct, and number of teeth for example 100, this will make the mill go to full depth at once and make only one revolution+lead in/out wich is set to "arc1" by default.
i use 3 cuts on tough materials, maybe even more on NPT. |
