機(ji)械(xie)零件的CNC加(jia)工(gong)(gong)，因結(jie)構形(xing)狀各種多樣，都是由平(ping)面(mian)(mian)、外圓(yuan)柱(zhu)面(mian)(mian)、內圓(yuan)柱(zhu)面(mian)(mian)或曲(qu)面(mian)(mian)、成(cheng)形(xing)面(mian)(mian)等基本表(biao)(biao)(biao)面(mian)(mian)組成(cheng)。每(mei)一種表(biao)(biao)(biao)面(mian)(mian)都有多種加(jia)工(gong)(gong)方法，具體選擇CNC加(jia)工(gong)(gong)方法時應根(gen)據零件的加(jia)工(gong)(gong)精(jing)度(du)、表(biao)(biao)(biao)面(mian)(mian)粗糙度(du)、材料(liao)、結(jie)構形(xing)狀、尺寸及生產類型等因素，選用相應的加(jia)工(gong)(gong)方法和加(jia)工(gong)(gong)方案

1、檢(jian)查使用(yong)的(de)刀(dao)(dao)(dao)具應與(yu)機床(chuang)允(yun)許的(de)規格相符。2、最大刀(dao)(dao)(dao)具長度，最大刀(dao)(dao)(dao)具重(zhong)量，刀(dao)(dao)(dao)具總重(zhong)不超過指定值。3、東莞CNC加工廠家分析，檢(jian)查使用(yong)的(de)刀(dao)(dao)(dao)具有(you)(you)無(wu)影響使用(yong)的(de)磨損(sun)、破損(sun)，有(you)(you)時應立即(ji)更換(huan)。

CNC又(you)叫(jiao)(jiao)做電腦鑼、CNCCH或數控(kong)機(ji)床其(qi)實是(shi)香(xiang)港那邊(bian)的(de)一(yi)(yi)種叫(jiao)(jiao)法，后來傳入大陸(lu)珠三角，其(qi)實就是(shi)數控(kong)銑床，在廣(guang)、江(jiang)浙滬一(yi)(yi)帶(dai)有(you)人叫(jiao)(jiao)“CNC加工(gong)(gong)(gong)中心”機(ji)械加工(gong)(gong)(gong)的(de)一(yi)(yi)種，是(shi)新型(xing)加工(gong)(gong)(gong)技術，主要工(gong)(gong)(gong)作是(shi)編制加工(gong)(gong)(gong)程序，即(ji)將(jiang)原來手(shou)工(gong)(gong)(gong)活(huo)轉為電腦編程。當然需要有(you)手(shou)工(gong)(gong)(gong)加工(gong)(gong)(gong)的(de)經驗

數(shu)控(kong)(kong)車(che)(che)(che)床(chuang)加工(gong)主(zhu)要(yao)針對(dui)木制品加工(gong)業的特點(dian)，結合操作習慣(guan)，使用了全漢字化操作，易學易用，可以加工(gong)柱體、錐體、弧形(xing)、球形(xing)等(deng)各(ge)種復雜形(xing)狀(zhuang)的回(hui)旋體木制件，可隨時(shi)(shi)靈(ling)活設置、迅速改(gai)變加工(gong)樣式，零件的加工(gong)批(pi)量應大于(yu)經普通車(che)(che)(che)床(chuang)濟批(pi)量數(shu)控(kong)(kong)車(che)(che)(che) 在非數(shu)控(kong)(kong)磨床(chuang)加工(gong)中(zhong)、小批(pi)量零件時(shi)(shi)，由(you)于(yu)各(ge)種原因，純(chun)切削時(shi)(shi)間只占實際工(gong)時(shi)(shi)的10％...

開粗：在機床(chuang)的(de)(de)(de)(de)(de)較大(da)(da)負(fu)荷(he)下(xia)，絕大(da)(da)局部狀(zhuang)況(kuang)應選(xuan)用盡能夠大(da)(da)的(de)(de)(de)(de)(de)刀(dao)(dao)，盡能夠大(da)(da)的(de)(de)(de)(de)(de)的(de)(de)(de)(de)(de)進刀(dao)(dao)量(liang)(liang)，盡能夠快的(de)(de)(de)(de)(de)進給。在同一把刀(dao)(dao)的(de)(de)(de)(de)(de)狀(zhuang)況(kuang)下(xia)，進給與(yu)進刀(dao)(dao)量(liang)(liang)成正比。普通狀(zhuang)況(kuang)下(xia)，機床(chuang)的(de)(de)(de)(de)(de)負(fu)荷(he)不是成績，選(xuan)刀(dao)(dao)的(de)(de)(de)(de)(de)準(zhun)繩次要依商品的(de)(de)(de)(de)(de)二維角與(yu)三維弧能否過小(xiao)來思索(suo)。選(xuan)好(hao)刀(dao)(dao)后，便定(ding)刀(dao)(dao)長，準(zhun)繩是刀(dao)(dao)長大(da)(da)于加工深(shen)度，大(da)(da)工件則要思索(suo)
