Ball screw and electronic lathe conversion

.....snipped.....So in metric if I want a M1.5 thread I just enter 1.5, if I want (doubt that I ever will) a 16 tpi then that is a pitch of 1.59 and so I enter 1.59.

I'm enthused with threading prospects just like that, figuratively speaking. Repair work can entail need of reproducing, more often only approximation of proprietary diameter and pitch combinations.
Now for CNC, not critical; but no way will I tie up funds and floorspace for those eventualities. Especially, when those cases demand few actual parts. Other features are handled as always, form tools, radiusing attachments, referencing stops and so on.
