刀具角度对钢轨铣削温度的仿真与试验研究
Simulation and Experimental Research on Influence of Tool Angle on Milling Temperature of Rail
摘要
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.关键词
