①CNC加工(gong)可大量減少工(gong)裝數(shu)量,加工(gong)形狀(zhuang)復雜的零件不需要復雜的工(gong)裝。如要改(gai)變零件的形狀(zhuang)和尺寸,只需要修(xiu)改(gai)零件加工(gong)程(cheng)序,適用(yong)于新產品研制和改(gai)型。
②CNC加(jia)(jia)工(gong)(gong)質量穩(wen)定,加(jia)(jia)工(gong)(gong)精度高,重復精度高,適應飛行器的加(jia)(jia)工(gong)(gong)要求(qiu)。
③CNC加工(gong)(gong)使(shi)多品(pin)種、小批量生(sheng)產情況下生(sheng)產效率(lv)較高,能減少(shao)生(sheng)產準備(bei)、機床調整和(he)工(gong)(gong)序檢驗的時(shi)(shi)間(jian),而且由于使(shi)用最佳(jia)切(qie)(qie)削(xue)量而減少(shao)了切(qie)(qie)削(xue)時(shi)(shi)間(jian)。
④CNC加(jia)工(gong)可加(jia)工(gong)常規方法難以(yi)加(jia)工(gong)的復雜(za)型面,甚至能加(jia)工(gong)一(yi)些(xie)無(wu)法觀測的加(jia)工(gong)部位。
數控加(jia)工(gong)的(de)缺點是(shi)機(ji)床設(she)備費用(yong)昂貴(gui),要求維修人員具(ju)有較高水平。
