| 摘 要： | 切削加工中,刀—屑接触区的应力分布直接影响着切削加工性能、切削温度分布及刀具磨损等,本文通过对直角切削时的切削力的分析和刀—屑接触长度的计算,建立了刀屑接触区的正应力与剪应力的分布计算模型,通过该模型可直接得到刀具前刀面的应力分布情况.

| Abstract: | The cutting performance, cutting temperature and tool wear are influenced by the stress distribution of tool - chip contact zone. In this paper, through the cutting force analysis and computation of tool - chip contact length in orthngonal cutting process, the model of normal stress and shear stress distribution are developed in the tool - chip contact zone, and the stress distribution can be computed directly using this model. |

| Keywords: | cutting force tool - chip contact zone finite element method |
