摘　　要：利用非线性有限元分析软件,对高速切削AISI 4340刀具应力进行仿真研究,分析不同刀具前角对刀具应力及温度的影响。针对所选用的几个角度,有限元分析结果表明,当刀具前角为-10°时,刀具前刀面应力分布相对均匀,而温度随刀具前角的减小而减小。Aimed at the influence of high-speed cutting tool rake angle on tool stresses and temperature,the nonlinear finite element analysis software was used to simulate the high speed cutting of AISI 4340 tool stress,the effect of the rake angle of the tool on the tool stress was also analyzed.The results showed that the stresses were relatively and uniformly distributed on the tool rake face when the tool rake angle was 10°,and the tool temperature decreased with the decreasing of rake angle.
