When the tool remove chips from the work area overhang length is long, decrease the number of revolutions and feed TOOL GEOMETRY ON PROGRAMMING When programming for CAM, the tool should be considered as a radius cutter. Usually, the corner radius should be set as R = 1.5 mm. If a larger radius is used, overcutting will occur. The following table shows the amount left uncut (t1) and overcut (t2).
