摘　　要：为了提高7075-T6铝合金的切削效率,采用单因素试验法基于ABAQUS软件分析不同刀具材料及刀具几何参数对切削力的影响。试验结果表明:使用YG8刀具切削加工7075-T6铝合金时受到的切削力最小;随着刀具前角的不断增大,切削力显著降低;随着刀具后角的不断增大,水平切削力的下降相对较缓,但垂直切削力显著降低。In order to improve the cutting efficiency of 7075-T6 aluminum alloy,the one-factor test method is used to analyze the influence of different tool materials and different tool geometry parameters on cutting force by ABAQUS.The test results show that the cutting force received when cutting and machining with YG8 tool is the smallest.With the continuous increase of the front angle of the tool,the resulting cutting force is significantly reduced.As the back angle of the tool continues to be increased,the horizontal cutting force is decreased relatively slow,but the vertical cutting force is decreased significantly.
