At the end of the day, speaking of these thread form tools. The forms ensured when the leading edge, trailing edge and crest are cutting. In CNC thats mostly the G76 function. That does a Z axis offset getting to depth, but the final spring cuts are at depth.

Wasn't it John Stevenson that ripped his entire top slide off and replaced it with solid mount. He does a lot of threads. All of them must be straight in.

I also take that approach and suspected that you would be doing it that way but wanted to check. I was trying to work out whether carbide inserts should even be used that way and thought it unlikely as you lose the advantage of the form.

John Stevenson (another CVA driver) - yes, well he does things that the rest of us can only wonder at. When I frequented HSM my usual reaction when I saw his stuff was that I was struck by the simplicity of what he'd done but also of the way he had attacked the problem. One of those people where you look at the results of their work and say "Of course that's what you'd do", but before you'd be scratching your head thinking "how the hell do you sort that problem?"
