基于有限元分析软件ABAQUS建立了高速切削Ti6Al4V的二维正交切削有限元模型,仿真研究了高速切削加工时切削速度、切削深度对切削力大小、切削力波动频率以及锯齿形切屑形态的影响.结果表明:平均切削力在90 m/min～360 m/min的切削速度范围内趋于平稳,随着切削深度的增大而增大;切削力波动频率随切削深度的增加而减小,随切削速度的增大而增大;切屑锯齿化程度及锯齿化步距都随切削速度及切削深度的增大而增大.

In this paper,a finite element model of two-dimensional(2D)orthogonal cutting of high speed cutting Ti6A14V was established based on ABAQUS finite element analysis software.The simulation of the high-speed machining investigated the influences on cutting force,cutting force fluctuation frequency and serrated cutting shape that caused by cutting speed and cutting depth.The result shows that cutting force tends to be stable in the range of 90 m/min to 360 m/min,and will increase with the increase of cutting speed.Meanwhile,the fluctuation frequency of cutting force will decrease with the increas...
