Abstract: Based on the analysis of friction between the rake face of metal-cutting tool and the chip as well as between the flank face of metal-cutting tool and the machined surface, the friction process and the chip forming in the two-dimensional metal cutting process are both numerically simulated by means of FEM software. The equivalent stress between the contacting nodes on the friction face of the chip-cutting tool is calculated. The modeling by FEM method and the calculating process are also described. Through the comparison between the calculating results of the simulation of the shearing angle and the experiment data obtained by the rapid tool-dropped method, the feasibility of this method is confirmed. This method is new and unique. Its application will be helpful to the theoretical study of metal cutting and the design of the cutting tools.

Key words: numerical simulation, finite element method, metal cutting, friction in the rake and flank face of metal cutting
