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。

The influencing orderliness of the cutting depth and the rake Angle of the tool on cutting qualities are found and the mathematical models are built.
得出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 results show that the effects on surface roughness are feed speed, depth of cutting , tool rake angle and parts hardness in turn.
