粗糙

The results show that the surface roughness decreases with increase of the inclination angles within the range of 10° to 30°. After the angle approaches to 30°, increase of the inclination angle causes increase of the surface roughness. Furthermore, the effect of inclination angles on cutting speed was investigated.
