Fig. 5-15: Chamfer as contour transition and corrected NC-block transition point
When arcs or chamfers are inserted as contour transitions, the CNC auto-
matically generates an additional transition NC-block. This NC-block is con-
sidered to be an independent NC-block, and as such it must be started
separately in single-block processing mode.
