在(zai)(zai)數(shu)控(kong)加(jia)工過程(cheng)中，進給(gei)速(su)度(du)也(ye)可通過機床控(kong)制面板上的(de)(de)進給(gei)倍率(lv)修調開關進行人工調整，但是(shi)1大(da)進給(gei)速(su)度(du)要受到(dao)設備剛(gang)度(du)和(he)進給(gei)系統性能(neng)等(deng)的(de)(de)限制。隨著數(shu)控(kong)機床在(zai)(zai)生(sheng)產實際中的(de)(de)廣(guang)泛應用(yong)，數(shu)控(kong)編(bian)程(cheng)已經成(cheng)為數(shu)控(kong)加(jia)工中的(de)(de)關鍵問題之一。在(zai)(zai)數(shu)控(kong)程(cheng)序的(de)(de)編(bian)制過程(cheng)中，要在(zai)(zai)人機交互(hu)狀(zhuang)態(tai)下即時選(xuan)擇(ze)刀具和(he)確定(ding)(ding)切(qie)削(xue)用(yong)量(liang)。因(yin)此，編(bian)程(cheng)人員必須熟悉刀具的(de)(de)選(xuan)擇(ze)方法和(he)切(qie)削(xue)用(yong)量(liang)的(de)(de)確定(ding)(ding)原則，從(cong)而保證零件的(de)(de)加(jia)工質(zhi)量(liang)和(he)加(jia)工效(xiao)率(lv)，充分發(fa)揮數(shu)控(kong)機床的(de)(de)優點。
