Hello,
Is it possible to increment X on a lathe so that you could have a defined profile and cut off a little at a time cutting back and forth with the Z? Is this a macro function?

Kind of like the G77 except a profile, not a line...

yes it is possible..do it all the time on my lathe..easy if you have a cam program..if you d'ont have a cam program,you can use a series of g77 to remove the maximum material around your profile then do a finishing pass
on your profile alone which has been converted to G codes with a program like
dxf2gcode..hope this helps...

Thanks for your reply. What cam program do you use?

All the G77 exampes I find are with a straight line. I will need to experiment....
