①CNC加工(gong)(gong)可大量減少工(gong)(gong)裝(zhuang)數量，加工(gong)(gong)形狀(zhuang)復(fu)雜(za)的(de)零件(jian)不需(xu)要復(fu)雜(za)的(de)工(gong)(gong)裝(zhuang)。如要改(gai)(gai)變零件(jian)的(de)形狀(zhuang)和尺寸，只(zhi)需(xu)要修(xiu)改(gai)(gai)零件(jian)加工(gong)(gong)程序，適用于新(xin)產品(pin)研制和改(gai)(gai)型。

②CNC加(jia)工質量穩定(ding)，加(jia)工精(jing)度高，重復精(jing)度高，適應飛行器的加(jia)工要求。

③CNC加工使(shi)多品種、小(xiao)批(pi)量生產情況下生產效率較(jiao)高，能減(jian)少生產準(zhun)備、機床調整和工序檢(jian)驗的(de)時間(jian)，而且(qie)由于使(shi)用最佳切削量而減(jian)少了(le)切削時間(jian)。

④CNC加(jia)(jia)工(gong)(gong)(gong)(gong)可加(jia)(jia)工(gong)(gong)(gong)(gong)常規(gui)方法難以(yi)加(jia)(jia)工(gong)(gong)(gong)(gong)的(de)復雜型(xing)面，甚至能加(jia)(jia)工(gong)(gong)(gong)(gong)一些無法觀(guan)測(ce)的(de)加(jia)(jia)工(gong)(gong)(gong)(gong)部位。

數控(kong)加(jia)工的缺點(dian)是機床設備(bei)費用昂(ang)貴，要求維修人(ren)員(yuan)具有較(jiao)高水平。
