摘　　要：针对42CrMo钢齿槽铣削过程,基于Johnson-Cook本构模型和Usui磨损模型,建立单个可转位刀片铣削齿槽的有限元仿真模型,分析切削用量与刀具前角对切削力、切削温度和刀具磨损的影响。仿真结果显示:进给量对主切削力的影响较为显著,而对切削温度的影响较小;切削速度对主切削力的影响相对较小,但对切削温度的影响较大。通过实验进一步分析,刀片的主要磨损形式为前刀面的月牙洼磨损,验证了磨损仿真结果的准确性。Based on the Johnson-Cook constitutive model and Usui wear model,the finite element model of single indexable inserts is established for milling process of 42CrMo teeth space.The effects of cutting parameters and tool rake angle is established for milling on cutting force,cutting temperature and tool wear are analyzed.The simulation results show that the feed rate has a significant effect on the cutting force,but has little effect on the cutting temperature.The influence of cutting speed on main cutting force is relatively small,but it has a great influence on the cutting temperature.Through the teste analysis of the wear failure,it is found that the main wear form is the crater wear on the rake face,which verifies the wear simulation results.
