The right cutter, insert, and cutting conditions can boost tool life 30% in this highly aggressive cutting process. Many engineers still believe finish passes should remove 0.13-0.25 mm. A better choice in most work materials is a depth of cut of 0.38-0.64 mm. When the carbide inserts do not have enough materials to bite into, the tool will rub against the work surface instead of cutting, reducing tool life and surface finish quality. Improving tool life and surface finish specifically may require a change in cutter geometry, insert grade, insert entry angle, and operating conditions.
