通过逆铣所得机加工表面质量不是很高。
The quality of the machined surface obtained by up milling is not very high.
然而逆铣仍经常被用在工业上，尤其是粗切削时。
Nevertheless, up milling is commonly used in industry, especially for rough cuts.
可采用逆铣和顺铣方法加工齿轮，可以轴向或径向进行加工。
With it pinions can be machined with hob or single-tooth indexing, also can with shaft cut-in and radial cut-in method.
