It also shows that the chip flow direction is closer to the maximum inclination direction of a rake face with an increase in a normalrake Angle.
文中还提出，随着法向前角增大，流屑方向将愈接近前刀面最大倾斜方向。

Based on equation of cutting edges, new geometric model and NC grinding model of rake face of ball end mill with constant normalrake Angle are modeled.
本文基于刀刃曲线方程，推导了球头等法前角前刀面的几何模型及其数控磨削模型。

Based on the experiment, the influences of tool normalrake, chip pulling Angle and chip pulling force on the shape and metallurgical structure of the fiber cross section are studied.
