| Abstract: | Based on the numerical simulation and FEM software, the chip forming and the stress-strain distribution in cutting zone for the two-dimensional metal cutting process have been simulated, and also the shearing angle and the change of cutting force in the beginning of metal cutting process have been calculated. Through experiments, the feasibility of this method is confirmed. This method is new and unique. Its application will be helpful to the analysis of metal cutting principles and to the design of the cutting tool. |
