摘要

摘要: 刀具角度与切屑的形成、铣削力、铣削温度、刀具磨损和被加工表面质量有着重要的联系。为了分析刀具几何角度对第一变形区铣削温度的影响，利用AdvantEdge对U71Mn铣削过程建立了3D仿真模型；同时，采用K型人工热电偶测量了第三变形区—刀/工面处铣削温度，并探究了工艺参数对铣削温度的影响规律。试验结果表明：随着刀盘转速、进给速度和背吃刀量的增加，铣削温度逐渐升高；其中，刀盘转速和背吃刀量对切削温度有着更为显著的影响，而进给速度的影响则较小。然后采用红外热像仪对第二变形区刀/屑面的铣削温度进行了测量，并将在同一切削参数条件下人工热电偶与红外热像仪的实测温度与仿真结果进行了比较，结果表明所建3D仿真模型的有效性。最后，在上述所建模型基础上仿真分析不同刀具角度对第一变形区切削温度的影响，为铣刀盘刀具结构设计提供一定的指导意义。

Abstract: In order to analyze the influence of tool geometry on the milling temperature of the first deformation zone,the 3D simulation modelfor the milling process of U71Mn was established with AdvantEdge. At the same time, the K type artificial thermocouple was used to measure the temperature of the third deformation zone, the cutter and the working surface, and the influence of the processing parameters on the milling temperature was also studied. The results showed that milling temperature gradually increased with the increasing of cutter speed, feed rate and cutting depth. Among them, the cutter speed and cutting depth has a more significant influence on the cutting temperature, but the speed of the feed is little. Then using thermal infrared imager on the second deformation zone knife/chip surface milling temperature were measured in with all cutting parameters under the condition of artificial thermocouple and thermal infrared imager measured temperature and the simulation results were compared. The results showed that the effectiveness of the 3D simulation model. Finally, based on the above mentioned model, the effects of the cutting tool angles on the cutting temperature of the first deformation zone was simulated and analyzed. The simulation results provided a guidance for the structure design of the milling cutter.
