Here is something off the wall
so to speak that you may want to try fooling with:
N10 G0 X1.0
N20 F40
N30 G76 X.875 Z-1 P.001 J .030 H.030 I 30 C.1 B.001
N40 M30
What i am doing is tricking the thread cycle such that the pitch is very fine but the cut depth is what ever i want. (the
program dosen't know what you tool radius is )
It then does the passes down to the diameter wanted. Set your x axis location at 1.0. when the code is read by Mach it will generate all the paths. Not a canned cycle, but it just may be a shortcut.
RICH
BTW, NEVER ACTUALY CUT SOMETHING WITH IT, BUT HAVE DRY RUN IT!
