摘　　要：振动钻削特殊的切削机理能显著降低钻削过程中的切削力。通过分析振动钻削过程中的钻头运动,推导了钻头在切削过程中所受轴向平均切削力的理论计算公式,并据此对振动钻削过程中切削参数和振动参数对轴向平均切削力的影响进行了定性分析。The special cutting mechanism of vibration drilling can decrease obviously its cutting force. Through analyzing the tool motion in the vibration drilling, the theoretical calculating formula of the average axial cutting force exerted on the tool during the vibration cutting process is deduced, and the influence of the cutting parameters and vibration parameters on average axial cutring force during the vibration drilling process are analyzed qualitatively based on the formula.
