摘　　要：基于有限元方法建立了H13钢硬态车削的仿真模型,应用Ti N、Ti C、Ti Al N、Al2O3涂层刀具对硬态切削H13钢在切削速度100-400m/min范围内的切削温度进行了模拟研究,重点分析了刀具前刀面上关键点的温度变化趋势及切削速度对该点温度的影响。仿真结果表明:涂层材料对切削温度产生一定影响,Ti C涂层刀具切削时温度最低;切削速度对切削温度有直接影响,切削速度越高,切削温度越高,越容易形成锯齿形切屑;刀具前刀面温度最高点出现在前刀面靠近刀尖的一点,即容易形成月牙洼磨损的位置。The simulation model of hard cutting H13 steel has been established by finite element method. Cutting temperature has been simulated with different tools coating（ Ti N,Ti C,Ti Al N,Al2O3） and different cutting speed（ 100-400 m / min）. Analyze the temperature trends of key point on the rake face. The simulation results are follows,the temperature was lowest when use Ti C coating tool. The cutting speed has direct impact on cutting temperature. The higher the cutting speed,the higher the cutting temperature,and the easier the formation of serrated chip. Peak of tool temperature appeared on the rake face near the tip that is the position of crater wear formation.
