粗糙的

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.

研究结果表明：工件倾角的大小对已加工表面粗糙度有明显的影响，在倾角为10°～30°时，表面粗糙度随着工件倾角的增大而降低；此后，随着倾角的进一步增加，表面粗糙度有所升高。
