Abstract

Based on the study on metal cutting theories and rigid-plastic finite element method, taking Sweden SECO lathe tool MDT as the researching object, the cutting force in cutting process is analyzed after a cutting process simulation model is constructed using finite element method. Different simulation parameters and cutting parameters are used to carry out analyses time after time. The dynamic changing curves of the cutting force in cutting process are obtained. Through the comparison of the cutting force in different cutting conditions, the influence of cutting parameters on the cutting force is summarized. The research can provide useful data for improvement of metal cutting technology and tool cutting performance.
