Use corner finishing NC sequences to automatically machine corners and valleys that cannot be reached by a previous tool. Corner finishing NC sequences calculate the area left by the previous tool in corners and valleys, perform a slope-based machining operation on this remaining area, and compute the tool path for machining.

You must define the area to be machined using a Mill Window. Within this Mill Window, Creo NC calculates the remaining area in corners and valleys using the following elements:

You can use ball end, radius end (Bull Nose type), and flat end milling tools for corner machining. Creo NC provides automatic gouge checking and avoidance for the tool and the tool holder.
