The effect of tool rake angle on the geometric shapes of the chip, cutting force and cutting temperature is investigated.
分析了刀具前角对切屑几何形状、切削力和切削温度的影响。
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。
