摘　　要：GH625镍基高温合金因其优良的高温性能而被广泛应用于航空发动机部件中,但在其车削加工存在加工残余应力较大的问题。本文采用有限元和试验相结合的方式对PVD硬质合金涂层刀具端面车削GH625镍基高温合金的残余应力进行研究,分析了车削速度、进给量和车削深度三个因素对加工残余应力的影响规律,获得了残余应力最优的车削参数组合。Nickel-based superalloy GH625 is widely used in aero-engine components due to its excellent high temperature performance,but there is a problem of large machining residual stress in its cutting process.In this paper,the residual stress of GH625 cutting tool with hard total PVD coating is studied by combining finite element and experiment.The influence of turning speed,feed rate and cutting depth on the residual stress is analyzed,and the optimal turning parameter combination of residual stress is obtained.
