The research result in the paper shows that accurate tool face angle can still be obtained under this circumstance.
研究表明，即使在这种情况下，完全可以求得准确的工具面角；
It is the Angle between the face of the tool called the rake face and the normal to the machining direction.
它是被称为前倾面的刀具面与垂直机加工方向的夹角。
Higher the rake Angle, better is the cutting and less are the cutting forces, increasing the rake Angle reduces the metal backup available at the tool rake face.
前角越大，则切削越好且切削力越小，增加前角可以减少刀具前倾面上产生的金属阻塞。
