Abstract: As heavy cutting is widely used in the energy field of China, it has important significance to study the cutting mechanism. Based on this reason, this paper has overcome limitations of the traditional cutting method, established a reasonable boundary conditions by using finite element analysis software Third Wave, and used accurate material constitutive model to build finite element simulation model on heavy cutting process, The effect of the cutting parameters to the cutting process is studied by simulation results, and chip formation is analyzed. The results provide a theoretical basis for the optimization on heavy cutting conditions.

Abstract: Cutting force can response changes in cutting process deeply, so it is important for studying cutting force on revealing the milling mechanism. For this reason, based on the support of finite element theory, a mesh adaptation method is used to establish the simulation model on die tool Cr12MoV during high-speed milling by simulation software ThirdWave, and the effects of different cutting conditions on cutting force are studied by simulation method, which has verified the simulation results by experiments. The results of research also have certain reference significance on the optimization of cutting process and hard milling mechanism.
