Rest machining

Rest machining determines the model areas where material remains after the machining by a tool path, and generates a set of passes to machine these areas.

Pencil milling vertical corners can cause both the flute of the tool and the radius to be in full contact with the material, creating adverse cutting conditions. Rest machining picks the corners out from the top down, resulting in better machining technique. Steep and shallow areas are both machined in a single tool path with different rest machining strategies.
