摘　　要：建立了钻削加工仿真模型,并采用麻花钻对钛合金进行振动钻削试验。利用ABAQUS软件进行轴向超声振动钻削仿真,试验验证和对比分析了轴向超声振动钻削在不同加工参数下的切屑形态和钻削力。仿真与试验结果表明:随着进给量和振幅增加,钻削力增大,但进给量对钻削力的影响大于振幅;无论是进给量还是振幅的改变,对切屑形态均有影响。A drilling simulation model is established,and vibration drilling experiments are performed by using twist drills to machine titanium alloys.The simulation of axial ultrasonic vibration drilling is conducted by using ABAQUS,and the experimental verification is also carried out.The chip shape and drilling force of axial ultrasonic vibration drilling under different processing parameters are analyzed.The simulation and experiment results show that the cutting force increases as the feed rate or amplitude increases,but the effect of the feed rate on the drilling force is greater than that of the amplitude,and there is an impact on the chip shape whether the feed rate or amplitude changes.
