摘　　要：利用Abaqus有限元分析软件,对石墨烯/Al-18Si-4Cu-Mg复合材料的铣削过程进行有限元模拟仿真,并对石墨烯质量百分含量为0%~0.7%的四组样品进行铣削性能测试,研究石墨烯/Al-18Si-4Cu-Mg复合材料的切削力变化特征。结果表明,Abaqus有限元软件建立的切削力模型与实测铣削力曲线变化趋势相似,说明Abaqus有限元仿真软件对石墨烯/Al-18Si-4Cu-Mg复合材料的切削仿真与实际铣削过程吻合;对比石墨烯质量百分含量分别为0.5%和0.7%时两组材料在不同主轴转速、切削深度及进给量条件下的切削力仿真曲线和实测铣削力曲线,表明当石墨烯含量为0.5%时石墨烯/Al-18Si-4Cu-Mg复合材料的强化相分布更均匀,切削力幅值变化相对较小。Based on the Abaqus finite element analysis software,the milling process of Graphene/Al-18Si-4Cu-Mg composites was simulated by finite element method,and the milling performance of specimens of Graphene with a mass percent content of 0%~0.7%was tested.And the cutting force variation characteristics of Graphene/Al-18Si-4Cu-Mg composites were studied.The results show that the cutting force model established by Abaqus finite element software is similar to the change trend of the measured milling force curve,which indicates that the cutting simulation Graphene/Al-18Si-4Cu-Mg composites by Abaqus finite element simulation software is consistent with the actual milling process.By comparing the cutting force simulation curves and measured milling force curves of two groups of materials with Graphene mass fraction of 0.5%and 0.7%at different spindle speed,cutting depth and feed rate,it shows that the reinforced phase distribution of Graphene/Al-18Si-4Cu-Mg composites is more uniform and the cutting force amplitude changes relatively little when the Graphene content is 0.5%.
