When the tool overhang chips from the work area. length is long, decrease the number of revolutions and feed. 85 ° 88° Cautionary points in use The use of a standard or long shank Tool geometry on programming 90° When using a long shank, please lower the cutting conditions (Vc, fz, ap) to 70% When programming for CAM, the tool should be considered as a radius cutter. of the maximum conditions for the standard shank. 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 Others overcut (t2).
