①CNC加(jia)工(gong)(gong)(gong)可大量減少工(gong)(gong)(gong)裝(zhuang)數量，加(jia)工(gong)(gong)(gong)形(xing)狀(zhuang)復雜的零(ling)件(jian)不需要(yao)復雜的工(gong)(gong)(gong)裝(zhuang)。如要(yao)改(gai)(gai)(gai)變零(ling)件(jian)的形(xing)狀(zhuang)和(he)尺(chi)寸，只需要(yao)修(xiu)改(gai)(gai)(gai)零(ling)件(jian)加(jia)工(gong)(gong)(gong)程序，適(shi)用于新產品研制和(he)改(gai)(gai)(gai)型。

②CNC加工(gong)質量穩定，加工(gong)精(jing)(jing)度(du)(du)高，重復精(jing)(jing)度(du)(du)高，適應飛行器(qi)的加工(gong)要求。

③CNC加工使多(duo)品(pin)種(zhong)、小批量生(sheng)產情況下生(sheng)產效率較高，能減(jian)(jian)少(shao)生(sheng)產準(zhun)備、機床調整(zheng)和工序檢驗的(de)時間，而(er)且由于使用最佳切削量而(er)減(jian)(jian)少(shao)了(le)切削時間。

④CNC加(jia)工(gong)(gong)(gong)可加(jia)工(gong)(gong)(gong)常規(gui)方法難以加(jia)工(gong)(gong)(gong)的復雜型(xing)面，甚至(zhi)能加(jia)工(gong)(gong)(gong)一(yi)些無法觀測的加(jia)工(gong)(gong)(gong)部位。

數(shu)控加工(gong)的缺(que)點是機(ji)床(chuang)設備(bei)費用昂貴，要求維修人員具有較高(gao)水(shui)平。
