| 摘 要： | 以7075铝合金为例,利用DEFORM仿真软件中的车削模块,建立铝合金切削有限元模型,对仿真结果进行分析,得到切削过程中切削力变化、工件应力及刀具表面切削温度分布等相关试验数据。通过切削力的测量试验验证仿真结果的有效性,结果表明仿真值与测量值的变化趋势一致,证明了仿真后处理结果的有效性。在此基础上研究刀具几何形状对切削过程的影响,该方法为生产实践中确定切削7075铝合金的刀具几何形状提供了新途径。

| Abstract: | Taking 7075 aluminum alloy as the cutting carrier,the finite element model of aluminum alloy cutting is established by using the turning module in DEFORM.simulation software.The simulation results are analyzed and the cutting force variation ,workpiece stress and cutting surface heat distribution are obtained.Through the cutting force measurement experiment,the results show that the variation trend of simulation value is consistent with that of measurement value,which proves the validity of the simulation post processing results.Based on this result,the influence of the tool geometry on the cutting process is studied.This method provides a new way to determine the tool geometry of cutting 7075 aluminum alloy i'n practice. |
