| 摘 要： | 采用单因素直角切削试验,对硬质合金刀具切削铝合金7050-T7451加工过程中形成的已加工表面残余应力进行了研究。使用X射线衍射应力测试技术对残余应力进行测量,得到了不同切削参数对应的残余应力值。通过考虑刃口半径的存在,阐述了已加工表面残余拉应力和压应力的产生机理,同时分析了切削速度、切削深度等参数对残余应力值的影响规律。

| Abstract: | In this paper,the residual stress when machining aluminum alloy 7050-T7451 using carbide cutting tool was investigated through a series of orthogonal cutting experiments. The residual stress was measured by the X-ray diffraction technique and the values of residual stress corresponded to different cutting parameters were obtained. The influence of the cutting tool edge radius in cutting process was considered. The mechanics of tensile and compressive stresses were discussed. Also,the effects of the cutting ... |
