Abstract

Based on metal cutting theory and the key technology of finite element simulation, this paper uses finite element software Deform to establish three-dimensional finite element simulation model and simulate cutting process. This paper uses the work piece material is IN718 high temperature alloys packaged in Deform, and analyzes the processing characteristics of high temperature, choosing the right tools and cutting dosages to simulate. Through the simulation we can get scraps forming process, the surface stress, strain, temperature and cutting force distribution of the workpiece and the tool. We can also get the change rule of cutting force and cutting temperature under the different cutting parameters. The simulation results provide the theoretical basis for the optimization of cutting parameter selection in production practice.
