英文摘要：

High-speed dry gear hobbing is a kind of green and efficient gear manufacturing process,which eliminated the use of cutting oil/liquid. Analyzing the cutting process of gear hobbing was an effective way to improve its performance. Based on a professional FEM simulation software De- form 3D,a finite element simulation model of the high-speed dry gear hobbing process was estab- lished,a numerical simulation of material removal process was achieved,and the law of chip deforma-tion and the distribution of cutting force and temperature were gotten,the main parameters affecting gear hobbing performance were confirmed. The analyses provide an effective support for the optimiza- tion of high-speed dry gear hobbing parameters.
