機械(xie)(xie)加(jia)(jia)(jia)工(gong)(gong)(gong)基(ji)(ji)準(zhun)(zhun)(zhun)(zhun)按(an)其作用(yong)不同，cnc機械(xie)(xie)加(jia)(jia)(jia)工(gong)(gong)(gong)，可分(fen)為(wei)設計(ji)基(ji)(ji)準(zhun)(zhun)(zhun)(zhun)和(he)工(gong)(gong)(gong)藝(yi)基(ji)(ji)準(zhun)(zhun)(zhun)(zhun)兩大類。設計(ji)基(ji)(ji)準(zhun)(zhun)(zhun)(zhun)在零(ling)(ling)件(jian)(jian)(jian)圖上用(yong)以確定(ding)其他點、線、面的(de)(de)(de)(de)(de)基(ji)(ji)準(zhun)(zhun)(zhun)(zhun)，稱為(wei)設計(ji)基(ji)(ji)準(zhun)(zhun)(zhun)(zhun)，就活(huo)塞來(lai)說，精(jing)密(mi)機械(xie)(xie)加(jia)(jia)(jia)工(gong)(gong)(gong)，設計(ji)基(ji)(ji)準(zhun)(zhun)(zhun)(zhun)指(zhi)活(huo)塞中心線和(he)銷(xiao)孔中心線。在進(jin)行機械(xie)(xie)加(jia)(jia)(jia)工(gong)(gong)(gong)的(de)(de)(de)(de)(de)時(shi)候(hou)，學會對零(ling)(ling)部(bu)件(jian)(jian)(jian)的(de)(de)(de)(de)(de)精(jing)度進(jin)行控制是很有必要的(de)(de)(de)(de)(de)一件(jian)(jian)(jian)事情，因為(wei)只有精(jing)度得到控制以后，才(cai)能夠讓加(jia)(jia)(jia)工(gong)(gong)(gong)出來(lai)的(de)(de)(de)(de)(de)零(ling)(ling)部(bu)件(jian)(jian)(jian)更能夠滿足精(jing)密(mi)需求。機械(xie)(xie)加(jia)(jia)(jia)工(gong)(gong)(gong)是一種用(yong)加(jia)(jia)(jia)工(gong)(gong)(gong)機械(xie)(xie)對工(gong)(gong)(gong)件(jian)(jian)(jian)的(de)(de)(de)(de)(de)外形(xing)尺寸(cun)或性能進(jin)行改變的(de)(de)(de)(de)(de)過(guo)程。按(an)被加(jia)(jia)(jia)工(gong)(gong)(gong)的(de)(de)(de)(de)(de)工(gong)(gong)(gong)件(jian)(jian)(jian)處于的(de)(de)(de)(de)(de)溫度狀態﹐分(fen)為(wei)冷加(jia)(jia)(jia)工(gong)(gong)(gong)和(he)熱(re)加(jia)(jia)(jia)工(gong)(gong)(gong)。

零件(jian)(jian)加(jia)(jia)工(gong)的幾何形(xing)狀(zhuang)精度(du)主要是指軸頸、外錐(zhui)面(mian)(mian)、莫氏錐(zhui)孔等(deng)的圓度(du)、圓柱(zhu)度(du)等(deng)，一般應將(jiang)其公差限制在(zai)尺寸(cun)公差范圍內。對精度(du)要求較(jiao)高的內外圓表(biao)面(mian)(mian)，應在(zai)圖紙上標注(zhu)其允(yun)許(xu)偏差。零件(jian)(jian)加(jia)(jia)工(gong)表(biao)面(mian)(mian)上，不應有(you)劃痕、擦(ca)傷等(deng)損傷零件(jian)(jian)表(biao)面(mian)(mian)的缺陷，加(jia)(jia)工(gong)的螺紋表(biao)面(mian)(mian)不允(yun)許(xu)有(you)黑皮(pi)、磕(ke)碰(peng)、亂扣和毛(mao)刺等(deng)缺陷。所有(you)需要進行涂(tu)裝(zhuang)的鋼鐵制件(jian)(jian)表(biao)面(mian)(mian)在(zai)涂(tu)漆前，必(bi)須將(jiang)鐵銹、氧化皮(pi)、油脂、灰(hui)塵、泥土(tu)、鹽和污物等(deng)除去。機械加(jia)(jia)工(gong)是一種用加(jia)(jia)工(gong)機械對工(gong)件(jian)(jian)的外形(xing)尺寸(cun)或(huo)性(xing)能進行改變(bian)的過程。按被加(jia)(jia)工(gong)的工(gong)件(jian)(jian)處(chu)于的溫度(du)狀(zhuang)態﹐分為(wei)冷加(jia)(jia)工(gong)和熱加(jia)(jia)工(gong)。
