Other aspects are very important, Angle, shape, hardness, cuttingedge toughness, joint precision, smooth opening and closing, handle design and surface treatment.
其他方面也非常重要：角度，形状，硬度，剪切边的韧性，接合处精密、顺畅的开合，手柄设计和表面处理。

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。
