CNC是英文Computerized Numerical Contro也就是技(ji)術數字化控制(zhi)的縮(suo)寫。采用傳統工(gong)藝(yi)與CNC數控加工(gong)有什么區別(bie)，優(you)勢在哪里，這(zhe)個需(xu)要做(zuo)一下詳細的對(dui)比。

我(wo)們知(zhi)道傳統的(de)機械加工的(de)特(te)點，一般是用(yong)(yong)手(shou)工操(cao)作普通機床作業機械的(de)加工，加工時(shi)(shi)需(xu)要(yao)用(yong)(yong)手(shou)動(dong)(dong)的(de)操(cao)作，搖動(dong)(dong)機械把手(shou)使刀具(ju)切削金屬后完(wan)成加工目標。在操(cao)作時(shi)(shi)需(xu)要(yao)靠(kao)眼睛用(yong)(yong)卡尺等工具(ju)測量定好產品(pin)(pin)的(de)加工孔位，加工的(de)產品(pin)(pin)精度不高(gao)。特(te)別當產品(pin)(pin)的(de)孔位多(duo)、精度高(gao)時(shi)(shi)很難達到標準。

而(er)采用CNC數(shu)控(kong)(kong)(kong)加(jia)工(gong)中心就(jiu)不(bu)一(yi)(yi)樣(yang)了，它是(shi)采用一(yi)(yi)種編(bian)(bian)(bian)(bian)程(cheng)(cheng)控(kong)(kong)(kong)制(zhi)自動化(hua)機床的。可以(yi)通過編(bian)(bian)(bian)(bian)程(cheng)(cheng)控(kong)(kong)(kong)制(zhi)系(xi)統能夠有邏(luo)輯(ji)地處理控(kong)(kong)(kong)制(zhi)好(hao)(hao)編(bian)(bian)(bian)(bian)碼(ma)和符號指(zhi)令規(gui)定的程(cheng)(cheng)序，通過計算機將(jiang)其譯碼(ma)，按照設計好(hao)(hao)的動作，通過刀具切(qie)削鋁型材產品，將(jiang)毛坯加(jia)工(gong)成半成品零部(bu)件(jian)。通過CNC數(shu)控(kong)(kong)(kong)加(jia)工(gong)中心加(jia)工(gong)的產品，精(jing)度高可以(yi)達(da)到0.01毫米。不(bu)光精(jing)度高還可以(yi)任(ren)意編(bian)(bian)(bian)(bian)程(cheng)(cheng)去掉(diao)不(bu)需要的部(bu)分，打孔、攻絲、銑槽、切(qie)割(ge)等等，可以(yi)一(yi)(yi)步到位的完成。

正(zheng)因為CNC數(shu)控加(jia)(jia)工(gong)中心(xin)的優勢特別的明顯，更(geng)多(duo)的企業青睞CNC加(jia)(jia)工(gong)中心(xin)加(jia)(jia)工(gong)的產(chan)品配套使用到機械設備上。特別做少量(liang)樣(yang)品時(shi)，產(chan)品的精(jing)度要求(qiu)、孔位不對稱(cheng)時(shi)， CNC數(shu)控加(jia)(jia)工(gong)就可以(yi)解燃眉之急(ji)啦。江(jiang)蘇(su)有(you)一家南京美(mei)誠鋁業擁有(you)多(duo)臺6.5米的CNC數(shu)控加(jia)(jia)工(gong)中心(xin)，可以(yi)解決長(chang)尺寸(cun)的鋁型材產(chan)品加(jia)(jia)工(gong)需求(qiu)。

CNC數控加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)(gong)藝(yi)是機械(xie)加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)的(de)一種，也(ye)遵守機械(xie)加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)切(qie)削規律，與普通機床的(de)加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)(gong)藝(yi)大體相(xiang)同。由(you)于它是把計(ji)算機控制技術應用于機械(xie)加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)之中的(de)一種自動化加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)，因而具(ju)有加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)效率高、精度高等(deng)特點，加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)(gong)藝(yi)有其獨(du)特之處，工(gong)(gong)(gong)(gong)(gong)(gong)序較(jiao)(jiao)為(wei)(wei)復雜，工(gong)(gong)(gong)(gong)(gong)(gong)步安排較(jiao)(jiao)為(wei)(wei)詳盡周密(mi)。

CNC數(shu)控(kong)加(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝包(bao)括(kuo)刀具的(de)(de)(de)選擇、切(qie)削參數(shu)的(de)(de)(de)確定(ding)及走刀工(gong)(gong)(gong)藝路線的(de)(de)(de)設計等內容。CNC數(shu)控(kong)加(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝是(shi)數(shu)控(kong)編(bian)程(cheng)(cheng)的(de)(de)(de)基礎及核心(xin)，只有工(gong)(gong)(gong)藝合理，才能編(bian)出(chu)高(gao)效率和(he)高(gao)質量(liang)的(de)(de)(de)數(shu)控(kong)程(cheng)(cheng)序(xu)。衡量(liang)數(shu)控(kong)程(cheng)(cheng)序(xu)好(hao)壞的(de)(de)(de)標(biao)準是(shi)：.少的(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)時(shi)間、.小的(de)(de)(de)刀具損耗及加(jia)(jia)工(gong)(gong)(gong)出(chu).佳效果的(de)(de)(de)工(gong)(gong)(gong)件。

數(shu)控加工工序(xu)是工件(jian)整體加工工藝的(de)一(yi)部分，甚至是一(yi)道工序(xu)。它要與(yu)其他前后工序(xu)相互配合，才能.終滿足整體機器(qi)或模具的(de)裝配要求，這(zhe)樣(yang)才能加工出合格的(de)零(ling)件(jian)。

數控加(jia)工(gong)(gong)工(gong)(gong)序一般分(fen)為粗加(jia)工(gong)(gong)、中粗清(qing)角(jiao)加(jia)工(gong)(gong)、半精加(jia)工(gong)(gong)及精加(jia)工(gong)(gong)等(deng)工(gong)(gong)步(bu)。

粗(cu)加工(gong)(gong)要(yao)盡量選用(yong)(yong)較(jiao)大(da)(da)的(de)(de)(de)(de)(de)刀(dao)，在(zai)機床(chuang)功率(lv)或刀(dao)具(ju)(ju)(ju)能(neng)承(cheng)受的(de)(de)(de)(de)(de)范圍內盡可能(neng)用(yong)(yong)較(jiao)大(da)(da)切(qie)削量快速地(di)切(qie)除大(da)(da)量的(de)(de)(de)(de)(de)工(gong)(gong)件(jian)材料。為了防(fang)止(zhi)粗(cu)加工(gong)(gong)時(shi)的(de)(de)(de)(de)(de)切(qie)削振動使工(gong)(gong)件(jian)松(song)動，在(zai)開粗(cu)后(hou)應(ying)該及時(shi)校表檢(jian)查(cha)，必要(yao)時(shi)重新對刀(dao)。可以在(zai)開粗(cu)后(hou)進行基準面的(de)(de)(de)(de)(de)精加工(gong)(gong)光(guang)刀(dao)，為以后(hou)校表檢(jian)查(cha)做好準備。對于(yu)具(ju)(ju)(ju)有(you)復(fu)雜型腔的(de)(de)(de)(de)(de)工(gong)(gong)件(jian)，由于(yu)開粗(cu)用(yong)(yong)了較(jiao)大(da)(da)刀(dao)具(ju)(ju)(ju)，使得角落處殘存大(da)(da)量的(de)(de)(de)(de)(de)余量，必須(xu)用(yong)(yong)比粗(cu)加工(gong)(gong)時(shi)較(jiao)小的(de)(de)(de)(de)(de)刀(dao)具(ju)(ju)(ju)進行二次開粗(cu)或清角。加工(gong)(gong)面積比較(jiao)大(da)(da)的(de)(de)(de)(de)(de)情況下，為了減少刀(dao)具(ju)(ju)(ju)損耗可以進行半精加工(gong)(gong)。以上各(ge)步為了防(fang)止(zhi)過切(qie)都必須(xu)留足夠多的(de)(de)(de)(de)(de)余量，.后(hou)進行精加工(gong)(gong)工(gong)(gong)序。一(yi)般情況下，盡量在(zai)機床(chuang)上檢(jian)驗，合(he)格后(hou)才(cai)拆下，再準備下一(yi)件(jian)加工(gong)(gong)。
