influencing orderliness of the cutting depth and the rake Angle of the tool on cutting qualities are found and the mathematical models are built.───了切削厚度与刀具前角这两个切削参数对切削质量影响的规律，得出二者关系的数学模型。

The calculating formulae of the chip - flow angle and the chip - flow rake angle are given.───给出了流屑角和流屑前角的计算公式.

This paper also discusses bit parameter design to improve the economy of PDC bits, such as negative rake Angle and side rotation Angle.───本文还介绍了为提高复合片钻头经济指标的钻头参数设计问题，如负前角，侧旋角等。

The results show that the effects on surface roughness are feed speed, depth of cutting , tool rake angle and parts hardness in turn.───结果表明：工件进给速度对表面粗糙度的影响最大，切削深度和刀具前角次之，工件硬度影响最小。
