摘要 利用ABAQUS有限元仿真软件建立了硬质合金立铣刀铣削TC4钛合金工件的三维铣削模型,以刀具的角速度和进给速度作为输入载荷变量,探讨了不同铣削参数对TC4钛合金切削温度场的影响。仿真结果表明,在相同背吃刀量下,刀具角速度、进给速度越大切削过程中温度场数值越大。进一步利用切削温度场经验计算公式及MATLAB软件进行数值分析。结果表明,切削温度场数值随背吃刀量、每齿进给量、切削速度增大而增大,且切削速度对TC4钛合金切削温度场影响最大,其次是每齿进给量,而背吃刀量对TC4钛合金切削温度场影响最小。 A three-dimensional milling model of hard alloy end mills milling TC4 titanium alloy workpiece was established by using ABAQUS finite element simulation software.The angular velocity and feed rate of the tool were used as input load variables to explore the effect of different milling parameters on the cutting temperature field of TC4 titanium alloy.The simulation results showed that under the same cutting depth,the higher the tool's angular velocity and feed rate,the larger the numerical value of the temperature field during the cutting process.A numerical analysis was performed by using the cutting temperature field empirical calculation formula and software MATLAB.The results showed that the numerical value of the cutting temperature field increased with the increase of the cutting depth,feed per tooth,and cutting speed.The cutting speed had the greatest influence on the cutting temperature field of TC4 titanium alloy,followed by feed per tooth,while the cutting depth had the smallest influence on the cutting temperature field of TC4 titanium alloy.
