摘要：为研究麻花钻的钻削参数对钛合金钻削温度的影响规律，采用DEFORM3D 软件对钛合金的钻削加工进行有限元仿真分析，建立钻削温度场模型，应用正交试验设计分析钻头直径、钻削速度和进给量三个钻削参数对钻削温度场的分布及温度的影响。通过极差分析，以图表直观反映各因素对钻削温度的影响程度，并获得最优钻削参数组合。仿真结果表明：钻削速度对于钻削温度的影响最为明显，进给量次之，钻头直径影响最小。

Abstract:In order to study the effect of twist drill drilling parameters on the drilling temperature field of titanium alloy，the drilling process of titanium alloy is analyzed by using DEFORM3D software finite element simulation.A model of drilling temperature field is established.The effects of three drilling parameters，which are drill diameter，drilling speed and feed rate on distribution of the drilling temperature field and temperature are analyzed by orthogonal experimental design.The effect of various factors on drilling temperature is directly reflected by the chart，and the optimum drilling parameter combination is obtained through range analysis.Simulation results show that the influence of drilling speed on drilling temperature is most obvious，feed rate is the next and drill diameter is the last.
