| 摘 要： | 采用3种类型的刀具车削航天用碳化硅晶须增强铝基复合材料(SiCw/LD2),用Kistler三向测力仪测量三向切削分力F_c、F_p、F_f,用原子力显微镜AFM检测刀具刃口及已加工表面的微观形貌和轮廓.结果表明,与圆形固定式刀具相比,硬质合金自转位刀具表现出类似金刚石刀具的优异耐磨性,其使用寿命延长60多倍,刀具的切入与切出平稳,切削过程颤振小;已加工表面质量较好,呈现铝基体的灰白铝色,破碎的碳化硅晶须及孔洞较少,表面粗糙度值较小;其三向切削力F_c、F_p、F_f都有不同程度的降低,尤其是平均背吃刀抗力F_p减少了30%～60%.硬质合金自转位刀具是切削加工中、低体积分数航天用碳化硅晶须增强铝基复合材料低成本高性能的一类刀具.

| Abstract: | Different types of cutting tools were used to cut SiC whisker reinforced aluminum composite.And then the 3-D components of cutting forces Fc,Fp,and Ff were measured with a Kistler 3-D dynamometer,and the microscopic pattern and profiles of the cutting edges and the machined surfaces were examined with an atomic force microscope(AFM).The results showed that,compared with fixed circular cutters the self-propelled rotary carbide tools had superior wear-resistance property similar to that of diamond tools.The t... |
