摘　　要：SiCp/Al复合材料是一种优异的轻质高强材料,超声振动钻削与普通钻削相比切削加工效果好,可有效减少切削力、切削热,提高工件的加工质量。采用大型有限元仿真软件Abaqus建立轴向超声振动钻削仿真模型,对超声振动钻削过程中的应力进行分析,结果显示轴向超声振动钻削能有效降低SiCp/Al复合材料加工时的应力。仿真结果表明,轴向振动钻削能够减小钻孔过程中的应力,减小断屑宽度,为SiCp/Al复合材料切削加工提供技术支撑。SiCp/Al is an excellent light and high strength material. Compared with ordinary drilling, ultrasonic vibration drilling’s cutting effect is better, which can effectively reduce the cutting force and cutting heat and improve the processing quality of the workpiece. In this paper, finite element simulation software of Abaqus is adopted to establish the axial ultrasonic vibration drilling, a simulation model of the stress in the process of ultrasonic vibration drilling is analyzed, the results show that the axial ultrasonic vibration drilling can effectively reduce the stress of SiCp/Al processing, the simulation results show that the axial vibration drilling can reduce the stress in the process of drilling, reduce the length of the chip breaker, it provides technical support for the cutting of SiCp/Al composites.
