In milling, high metal removal rate by large radial and axial depth of cut and high feed rates to achieve. Compared with the high-speed cutting (HSC), the cutting edge under HPC conditions bear cutting force is much greater, because the high-speed cutting is characterized by a smaller cross-section cutting, thus cutting force is also smaller. Therefore, the continuous cutting edge end mill is used for HPC processing, large cutting force generated would impede the use of the tool in the old and unstable performance of the machine, this machine power often seem not big enough. For the purposes of the processing, how often asked question HPC milling in the smaller power old-fashioned machine.
