The Finish pass cuts a path that is offset from the Groove feature's profile to the tool's tip center for the entire (defined) curve. The offset value is just the tool tip radius. Groove features are finished using a technique called shoulder stroking. This technique ensures that the grooving tool never cuts in the upward direction. Profiling proceeds in the -Z direction until the curve moves up in X. The tool then rapids to the highest point and cuts back in the +Z direction. This process repeats until the entire Groove is finished. This figure shows an example for a symmetric Groove with angled walls:
