I'm making some flange-shaped parts and need to turn some features on both sides of the flange itself. My lathe is a front-turret machine with a Fanuc OTC control. For the features on the -Z side of the flange, I want to use a G71 cycle with a left-hand tool . When using the G71 cycle for right-hand turning, the pullout moves are +X and +Z. More my left-hand turning, however, I need the pullouts to be +X and -Z. How can I accomplish this?
The pullout direction depends on the position of the tool just before calling G71.
For left-to-right turning, the tool should be placed to the left of the first point on the profile. Proper pullout would be automatically done.
