摘　　要：为给铣刀维护提供有价值的参考数据,间接提高铣刀表面磨损带的温度分布均匀度,根据铣刀的几何特征,在仿真试验环境下生成铣刀模型,并在铣削加工前采用夹丝—热电偶技术测定刀面磨损带的温度场分布情况。模拟铣削加工工艺,在不同的铣削温度工况下测得铣后刀面磨损带温度分布,通过对仿真试验数据的分析,得出铣削温度上升对铣前后刀面磨损带温度分布规律的影响仿真结果,并得出以下结论:随着铣削温度的上升,铣前刀面磨损带的温度升高,铣削温度越高,温度变化幅度越大,且铣后铣刀表面温度分布均匀度越高。In order to provide valuable reference data for the maintenance of the milling cutter and indirectly improve the temperature distribution uniformity of the wear zone on the surface of the milling cutter,according to the geometric characteristics of the milling cutter,the milling cutter specimen is generated in the simulation test environment.Before milling,the temperature field distribution of the wear zone on the surface of the milling cutter is measured by the sandwich thermocouple technology.The milling process is simulated,the temperature distribution law of the flank wear zone after milling under different milling temperature conditions is measured,and the numerical simulation results of the temperature distribution law of the flank wear zone is obtained before and after milling due to the rise of milling temperature through the processing of simulation test data.Through the analysis of the experimental data,it is concluded that with the increase of milling temperature,the temperature of the wear zone on the cutting surface before milling is increased.The higher the milling temperature is,the greater the temperature change range is,and the higher the uniformity of temperature distribution on the surface of milling cutter after milling is.
