摘　　要：以PCD刀具车削加工短切碳纤维/酚醛复合材料的表观质量为研究对象,通过开展正交试验,采用三维测量技术,研究切削三要素和刀尖圆弧半径对工件加工质量的影响;通过Design Expert软件,对加工因素的显著性进行分析。结果表明,随着切削速度v和进给量f的增大,表面粗糙度Ra逐渐增大,随着切削深度a_(p)和刀尖圆弧半径r的增大,R_(a)逐渐变小;试验显著因素为刀尖圆弧和进给量;最佳加工参数为:v=160 r/min、f=0.15 mm/r、ap=0.6 mm、r=0.6 mm;通过加工试验和建模分析验证,结论可靠。In this paper,a study on surface quality of chopped carbon fiber phenolic composites was carried out with the help of 3D measurement technology and orthogonal cutting test.The effect of three elements of cutting and tool nose arc radius on machining quality was researched.Significant factors on machining factors was analyzed through Design Expert.It is found that with the increasing of cutting speed and feed rate the corresponding surface roughness is increased,but reduced with the increasing of cutting depth and tool nose arc radius.The significant factors are tool nose arc radius and feed rate.The best combination of machining parameters are v=160 r/min,f=0.15 mm/r,a_(p)=0.6 mm,r=0.6 mm,and the conclusions are reliable by implementing cutting test and modeling analysis.
