機(ji)械零(ling)件加(jia)工(gong)(gong)變(bian)形(xing)(xing)的(de)(de)(de)改(gai)進措(cuo)施(shi)：在(zai)實(shi)際的(de)(de)(de)機(ji)械零(ling)件加(jia)工(gong)(gong)中(zhong)，導致零(ling)件變(bian)形(xing)(xing)的(de)(de)(de)因(yin)素很(hen)多。為了(le)從根本上解決這(zhe)些變(bian)形(xing)(xing)問(wen)題，操作(zuo)(zuo)(zuo)(zuo)人員需(xu)要(yao)(yao)在(zai)實(shi)際工(gong)(gong)作(zuo)(zuo)(zuo)(zuo)中(zhong)認真探索這(zhe)些因(yin)素，并結合工(gong)(gong)作(zuo)(zuo)(zuo)(zuo)精(jing)要(yao)(yao)，制定(ding)改(gai)進措(cuo)施(shi)。高(gao)(gao)精(jing)細(xi)機(ji)械制造工(gong)(gong)藝(yi)離不(bu)開高(gao)(gao)精(jing)細(xi)設備的(de)(de)(de)使用，其中(zhong)精(jing)細(xi)設備的(de)(de)(de)配件產(chan)品(pin)需(xu)要(yao)(yao)杰出的(de)(de)(de)物理安(an)穩性能(neng)作(zuo)(zuo)(zuo)(zuo)為基礎(chu)，安(an)徽(hui)機(ji)械加(jia)工(gong)(gong)，尤其是(shi)耐(nai)高(gao)(gao)溫(wen)，耐(nai)腐蝕的(de)(de)(de)耐(nai)久壽命作(zuo)(zuo)(zuo)(zuo)業，這(zhe)關于材(cai)料的(de)(de)(de)挑選(xuan)來說(shuo)硬(ying)質合金(jin)材(cai)料無疑(yi)是(shi)首(shou)要(yao)(yao)挑選(xuan)。通過刀具(ju)的(de)(de)(de)轉動和工(gong)(gong)件的(de)(de)(de)軸向(xiang)運動，銑床完成(cheng)了(le)金(jin)屬材(cai)料的(de)(de)(de)成(cheng)形(xing)(xing)。顯(xian)然，銑床在(zai)機(ji)械加(jia)工(gong)(gong)中(zhong)的(de)(de)(de)定(ding)位非常重要(yao)(yao)。

機(ji)(ji)械加(jia)(jia)工(gong)(gong)基準(zhun)按(an)其作用(yong)(yong)不(bu)同，可分為(wei)(wei)設計基準(zhun)和(he)(he)工(gong)(gong)藝基準(zhun)兩(liang)大類。設計基準(zhun)在(zai)零(ling)件(jian)(jian)圖上用(yong)(yong)以確定其他點、線、面(mian)的(de)(de)基準(zhun)，稱為(wei)(wei)設計基準(zhun)，就活塞(sai)來(lai)說，設計基準(zhun)指活塞(sai)中心線和(he)(he)銷孔中心線。在(zai)進(jin)(jin)行機(ji)(ji)械加(jia)(jia)工(gong)(gong)的(de)(de)時候，數控(kong)機(ji)(ji)械加(jia)(jia)工(gong)(gong)中心，學會對零(ling)部件(jian)(jian)的(de)(de)精(jing)度進(jin)(jin)行控(kong)制是很有(you)必要的(de)(de)一件(jian)(jian)事情，因為(wei)(wei)只有(you)精(jing)度得(de)到控(kong)制以后，才能夠(gou)讓(rang)加(jia)(jia)工(gong)(gong)出來(lai)的(de)(de)零(ling)部件(jian)(jian)更能夠(gou)滿足精(jing)密(mi)需求。機(ji)(ji)械加(jia)(jia)工(gong)(gong)是一種(zhong)用(yong)(yong)加(jia)(jia)工(gong)(gong)機(ji)(ji)械對工(gong)(gong)件(jian)(jian)的(de)(de)外形(xing)尺寸或性能進(jin)(jin)行改變(bian)的(de)(de)過程(cheng)。按(an)被(bei)加(jia)(jia)工(gong)(gong)的(de)(de)工(gong)(gong)件(jian)(jian)處于的(de)(de)溫度狀態﹐分為(wei)(wei)冷加(jia)(jia)工(gong)(gong)和(he)(he)熱加(jia)(jia)工(gong)(gong)。

機(ji)(ji)械(xie)(xie)加(jia)(jia)工(gong)(gong)(gong)的(de)(de)優勢：機(ji)(ji)械(xie)(xie)加(jia)(jia)工(gong)(gong)(gong)不(bu)需要開模，且自由度高(gao)；機(ji)(ji)械(xie)(xie)加(jia)(jia)工(gong)(gong)(gong)的(de)(de)精(jing)度非常高(gao)，有利于提高(gao)工(gong)(gong)(gong)件質量；機(ji)(ji)械(xie)(xie)加(jia)(jia)工(gong)(gong)(gong)的(de)(de)，有利于提高(gao)產量。機(ji)(ji)械(xie)(xie)加(jia)(jia)工(gong)(gong)(gong)基(ji)準(zhun)(zhun)(zhun)(zhun)按其作用不(bu)同，可分(fen)為設計(ji)基(ji)準(zhun)(zhun)(zhun)(zhun)和工(gong)(gong)(gong)藝基(ji)準(zhun)(zhun)(zhun)(zhun)兩(liang)大類。設計(ji)基(ji)準(zhun)(zhun)(zhun)(zhun)在(zai)零件圖上用以確定其他點、線、面的(de)(de)基(ji)準(zhun)(zhun)(zhun)(zhun)，稱為設計(ji)基(ji)準(zhun)(zhun)(zhun)(zhun)，機(ji)(ji)械(xie)(xie)精(jing)密加(jia)(jia)工(gong)(gong)(gong)，就(jiu)活塞來(lai)說，設計(ji)基(ji)準(zhun)(zhun)(zhun)(zhun)指活塞中心線和銷孔中心線。精(jing)密零件加(jia)(jia)工(gong)(gong)(gong)其實是(shi)機(ji)(ji)械(xie)(xie)加(jia)(jia)工(gong)(gong)(gong)的(de)(de)一(yi)種，但是(shi)因為對零件的(de)(de)加(jia)(jia)工(gong)(gong)(gong)精(jing)密度較高(gao)，對生產機(ji)(ji)械(xie)(xie)及流程要求也比較高(gao)。隨著工(gong)(gong)(gong)業化(hua)發展，機(ji)(ji)械(xie)(xie)加(jia)(jia)工(gong)(gong)(gong)廠家，精(jing)密機(ji)(ji)械(xie)(xie)加(jia)(jia)工(gong)(gong)(gong)分(fen)類越(yue)(yue)(yue)(yue)來(lai)越(yue)(yue)(yue)(yue)多，方(fang)向越(yue)(yue)(yue)(yue)來(lai)越(yue)(yue)(yue)(yue)細(xi)，越(yue)(yue)(yue)(yue)來(lai)越(yue)(yue)(yue)(yue)化(hua)。
