The research results show that the average axial cutting force and torque of common drill-grinding are greater than that of ultrasonic drill-grinding.
得出普通钻磨时的轴向平均切削力和平均扭矩均远大于超声钻磨加工时的轴向平均切削力和平均扭矩;

When the sample is at the stage of grinding damage, the axialforce and torque are related to the Young? S modulus, cohesion and internal friction Angle except the compression strength.
