When using longshank type cutters, the number of teeth may be different. In this case, the cutting conditions∙ Cutting conditions are generally limited by the rigidity and power of the machine and therigidity of the workpiece. When setting the conditions, start from half of the values of the should be changed by referring to: “The usage of standard and long shanks” shown in standard cutting conditions and then increase the value gradually while making sure the previous page. machine is running normally. 88° Cautionary points in use 90° The use of a standard or long shank Tool geometry on programming 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 of the maximum conditions for the standard shank. cutter. Usually, the corner radius should be set as R = 3.0 mm. If a larger Others radius is used, overcutting will occur.
