精(jing)密零(ling)件加(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝基準可以(yi)按照不(bu)同工(gong)(gong)(gong)藝分為：鑄造，鍛造，沖(chong)壓，焊(han)接(jie)，熱處理，機(ji)加(jia)(jia)工(gong)(gong)(gong)，裝配等等類別(bie)。精(jing)密零(ling)件加(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝過(guo)程(cheng)(cheng)一(yi)(yi)般是指(zhi)整個零(ling)件的數(shu)控加(jia)(jia)工(gong)(gong)(gong)與機(ji)器裝配過(guo)程(cheng)(cheng)的總稱(cheng)，而其(qi)他的如清洗、檢(jian)驗、設(she)備維護(hu)，油(you)封等等都僅(jin)僅(jin)只是輔(fu)助過(guo)程(cheng)(cheng)罷了。車削的方(fang)法(fa)改變原料或半成品(pin)的表(biao)面性能(neng)，這一(yi)(yi)過(guo)程(cheng)(cheng)我們稱(cheng)之為數(shu)控加(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝過(guo)程(cheng)(cheng)，精(jing)密零(ling)件加(jia)(jia)工(gong)(gong)(gong)行業中(zhong)數(shu)控加(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝過(guo)程(cheng)(cheng)就是其(qi)中(zhong)最為主要(yao)的工(gong)(gong)(gong)藝過(guo)程(cheng)(cheng)。

下面詳細介紹一下CNC精密零件加工的工藝基準(zhun)

（1）定位(wei)基準，在數控(kong)車床(chuang)進行加工時(shi)車床(chuang)或者(zhe)夾具所(suo)運用的定位(wei)基準。

（2）測量(liang)基準(zhun)(zhun)，這一基準(zhun)(zhun)通(tong)常指代的(de)是在檢驗時需要遵守的(de)尺寸或者位置的(de)標(biao)準(zhun)(zhun)。

（3）裝配基(ji)(ji)準，這一基(ji)(ji)準我們通常是指在進(jin)行(xing)裝配工(gong)藝時候(hou)零部件(jian)的位置標準。
