摘要

Abstract

In the process of high-speed milling, cutting force has a very important impact on tool life. This paper focused on modelling the cutting force in high-speed milling. According to oblique cutting model, a cutting force model of flank edge was presented firstly. Differential method was used in this process. The model was approached with calculating instantaneous chip thickness based on real tooth trajectory. Secondly, the cutting force model of chisel edge was adopted with the method of integral. The chisel edge was divided into millions of micro-units along. the direction that is normal to cutting edge. We got the cutting force of every unit. Then the model of chisel edge cutting force was gotten by means of integration. Force of the flank edge and the chisel one were combined. In the end, the model was programmed by means of Matlab. The result indicates that the numerical results agree well with the experimental data, the maximum error is 7. 14 percent between simulation and the experiment.
