Help Programming a Spiral Flute Threadmill

[RDEMIDON]

I have programmed straight flute threadmills tons of times, but now I only have a spiral flute threadmill and need to program it. Since I have never programmed a spiral flute I figured I would ask you fine folks how to do it. Do you program it the same as a striaght flute (go to the bottom of the hole and helix 1 pitch in Z +) or do you just go to the bottom of the hole and do a straight interpolation (Z doesn't move), or do you have to syncronize the speeds and feeds kind of like a tap?

Honestly, I treat them exactly the same

If "Z doesn't move"... you won't have a thread.

I am thinking he;s thinking about a helix lead in.......but you're right, no Z, no thread

Ah... I see what he's saying now... I'm a fan of Helical arc Entry/Exit. Rarely, would I plunge into a side wall for any operation.

Treated the same as long as your thread mill DOC is greater than your holedepth

I just tried programming it the same as a straight flute and it worked perfect. This is why I love this site. Thanks for all your help guys.
