摘　　要：刀具钝化通过改变刀具刃口形状提高切削过程的稳定性、提高刀具使用寿命和已加工表面质量。通过EDEM离散元方法建立硬质合金立铣刀的刀具刃口钝化模型,研究刀具钝化速度和钝化时间对刀具刃口磨损量的影响规律,为刀具钝化刃口优化提供理论依据,并为实现高速高效切削加工技术奠定基础。The tool edge preparation improves the stability of cutting process, prolongs the cutting tool life and improves the surface quality through changing the cutting edge shape. The edge preparation model of the carbide end milling cutter was established by the discrete element method EDEM, and the influence of the speed and the time on the tool edge wear was studied, which provided a theoretical basis for the optimization of the edge preparation, and lay the foundation for the reali- zation of high speed and high efficiency machining technology.
