摘    要:影响刀屑之间摩擦的因素非常多,摩擦状况很难确定.为了研究摩擦对切削加工的影响,利用有限元分析软件,模拟了不同摩擦系数下直角切削加工过程,得出摩擦系数增大,变形系数增加,切削温度升高,已加工表面残余应力增大,减小切削中的摩擦有利提高金属切削加工质量,延长刀具的使用寿命.

关 键 词:切屑  摩擦系数  变形系数  残余应力  金属切削  摩擦系数  数值分析  metal  cutting  friction  刀具的使用寿命  延长  加工质量  表面残余应力  温度升高  变形系数  加工过程  直角切削  模拟  分析软件  有限元  利用  切削加工  研究  摩擦状况

Abstract:There are many factors which affect the friction between tools and chips. The friction status is very difficult to confirm. In order to study the friction how affects the cutting process, this paper used the FEM analysis software to simulate the orthogonal cutting process with different friction coefficient. It can be draw conclusions that the residual stresses of machined surface are increasing with the raising of friction coefficient, the adding of deformation coefficient, the increasing of cutting temperature. The reduction of friction of cutting can do benefit for improving the machining quality and prolonging the working life of tools.
Keywords:Chip  Friction coefficient  Deformation coefficient  Residual stress
