數控(kong)加工切(qie)削用量(liang)的(de)(de)確定：(1)主軸轉(zhuan)速(su)(su)n(r/min)：1主軸轉(zhuan)速(su)(su)一(yi)般根據切(qie)削速(su)(su)度(du)來(lai)選(xuan)定。計算公式為(wei)：n=1000/d，式中d為(wei)刀(dao)具直徑(mm)。數控(kong)機床的(de)(de)控(kong)制面板上一(yi)般配(pei)有主軸轉(zhuan)速(su)(su)修調(diao)(倍(bei)率(lv))開(kai)關，可在加工過程中對主軸轉(zhuan)速(su)(su)進行倍(bei)率(lv)調(diao)整(zheng)。(2)進給速(su)(su)度(du)F：進給速(su)(su)度(du)應根據零件的(de)(de)加工精度(du)和表(biao)面粗糙度(du)要求以及刀(dao)具和工件材料來(lai)選(xuan)擇。

cnc數控加(jia)(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)序(xu)的安排(pai)：1、內(nei)外(wai)(wai)1交(jiao)叉原則(ze)對既有內(nei)表(biao)(biao)(biao)(biao)面(mian)(mian)（內(nei)型腔）又有外(wai)(wai)表(biao)(biao)(biao)(biao)面(mian)(mian)需要加(jia)(jia)工(gong)(gong)(gong)(gong)的零件(jian)，安排(pai)加(jia)(jia)工(gong)(gong)(gong)(gong)順序(xu)時，銅陵數控加(jia)(jia)工(gong)(gong)(gong)(gong)，應(ying)行內(nei)外(wai)(wai)表(biao)(biao)(biao)(biao)面(mian)(mian)粗加(jia)(jia)工(gong)(gong)(gong)(gong)，后進(jin)行內(nei)外(wai)(wai)表(biao)(biao)(biao)(biao)面(mian)(mian)精(jing)(jing)加(jia)(jia)工(gong)(gong)(gong)(gong)。切(qie)不可將零件(jian)上一部(bu)分表(biao)(biao)(biao)(biao)面(mian)(mian)（外(wai)(wai)表(biao)(biao)(biao)(biao)面(mian)(mian)或內(nei)表(biao)(biao)(biao)(biao)面(mian)(mian)）加(jia)(jia)工(gong)(gong)(gong)(gong)完畢(bi)后，再加(jia)(jia)工(gong)(gong)(gong)(gong)其他表(biao)(biao)(biao)(biao)面(mian)(mian)（內(nei)表(biao)(biao)(biao)(biao)面(mian)(mian)或外(wai)(wai)表(biao)(biao)(biao)(biao)面(mian)(mian)）。2、基(ji)面(mian)(mian)先(xian)1行原則(ze)應(ying)優先(xian)加(jia)(jia)工(gong)(gong)(gong)(gong)用作精(jing)(jing)基(ji)準的表(biao)(biao)(biao)(biao)面(mian)(mian)。這是因為定位(wei)基(ji)準的表(biao)(biao)(biao)(biao)面(mian)(mian)越精(jing)(jing)1確，裝夾誤(wu)差就越小。
