You don't need to make it complicated. Position the tool where needed and feed A until you get to the first radius going into one of the tabs. Stop the A right there and lead out along that radius. Then reenter the cut and interpolate the step without moving A. Reposition so Y is on centerline with A again and keep cutting until you encounter the next tab.
If you're programming manually, just make the above into a local sub and loop it in Z until you're through, then change your D number for that tool and run the finish pass. No biggie. |
