①CNC加(jia)工(gong)(gong)可(ke)大量減(jian)少工(gong)(gong)裝數(shu)量，加(jia)工(gong)(gong)形(xing)狀復(fu)雜的(de)零(ling)件(jian)(jian)(jian)不(bu)需(xu)要(yao)(yao)復(fu)雜的(de)工(gong)(gong)裝。如(ru)要(yao)(yao)改(gai)變零(ling)件(jian)(jian)(jian)的(de)形(xing)狀和尺(chi)寸，只需(xu)要(yao)(yao)修改(gai)零(ling)件(jian)(jian)(jian)加(jia)工(gong)(gong)程序，適用于新產品(pin)研(yan)制和改(gai)型。

②CNC加工(gong)質(zhi)量穩定，加工(gong)精度(du)高(gao)，重復(fu)精度(du)高(gao)，適應飛(fei)行器的加工(gong)要求。

③CNC加工(gong)使(shi)(shi)多品種(zhong)、小批量生(sheng)產情況下(xia)生(sheng)產效率較(jiao)高(gao)，能減少生(sheng)產準備、機床調整(zheng)和工(gong)序(xu)檢驗的時(shi)間(jian)，而且由于使(shi)(shi)用最佳切削(xue)(xue)量而減少了切削(xue)(xue)時(shi)間(jian)。

④CNC加工(gong)(gong)(gong)可加工(gong)(gong)(gong)常規方(fang)法難以加工(gong)(gong)(gong)的(de)復雜型面，甚至能加工(gong)(gong)(gong)一些無法觀測的(de)加工(gong)(gong)(gong)部(bu)位。

數(shu)控加工的缺點是機床(chuang)設(she)備費用昂貴，要求維修人員具有較高水平。
