摘要：Bearing steel 20CrMnTi used in cycloidal gear is a kind of difficult to machine material. Based on the finite element method of rigid viscoplastic, a three-dimensional finite element model that can reflect the actual milling process is established using the finite element software Deform-3D. The milling process of bearing steel 20CrMnTi is simulated. The milling force curve of milling process is obtained and the chip formation process of the milling process is analyzed. The distribution of temperature and stress field of the work piece and the tool is obtained. The effect of milling speed on milling force is researched. The study can provide a theoretical basis for optimization of process parameters in high speed milling bearing steel 20CrMnTi.
