Low friction-the coefficient of friction between the chip and tool should be low. This would allow for lower wear rates and better chip flow.
低摩擦系数—切屑与刀具间的摩擦系数应当较低。这会使磨损率较小及切屑流动更好。
It also shows that the chip flow direction is closer to the maximum inclination direction of a rake face with an increase in a normal rake 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。
