According to the result of right Angle free cutting experiment, the mathematical model of the cutting force for the arc-edge insert is established.

根据直角自由切削的试验结果，建立了圆弧刃刀片切削力数学模型，同时编制了软件进行预测。

Such an Angle is not too sharp in order to allow the use of blades that are not too thin for maintaining a stable quality of the blades at the cutting edge.

这个角度不太锋利是为了使用不太薄的刀片以维持刀锋处稳定质量。
