大型機械(xie)(xie)(xie)加工(gong)(gong)所使用(yong)的(de)(de)材(cai)料(liao)，可以說這也是(shi)一重要(yao)方面，所以是(shi)需要(yao)引(yin)起(qi)重視并認真(zhen)對待，而且是(shi)要(yao)選(xuan)擇(ze)性能(neng)(neng)和(he)(he)質量好的(de)(de)材(cai)料(liao)，這樣(yang)可以讓(rang)通過(guo)(guo)加工(gong)(gong)得到(dao)的(de)(de)工(gong)(gong)件(jian)有(you)好的(de)(de)使用(yong)性能(neng)(neng)和(he)(he)使用(yong)效果，而不(bu)會(hui)在使用(yong)過(guo)(guo)程(cheng)中出現一些問題。工(gong)(gong)藝(yi)(yi)過(guo)(guo)程(cheng)又可分為鑄造、鍛(duan)造、沖壓、焊接、機械(xie)(xie)(xie)加工(gong)(gong)、裝配等工(gong)(gong)藝(yi)(yi)過(guo)(guo)程(cheng)，機械(xie)(xie)(xie)制(zhi)造工(gong)(gong)藝(yi)(yi)過(guo)(guo)程(cheng)一般是(shi)指零件(jian)的(de)(de)機械(xie)(xie)(xie)加工(gong)(gong)工(gong)(gong)藝(yi)(yi)過(guo)(guo)程(cheng)和(he)(he)機器的(de)(de)裝配工(gong)(gong)藝(yi)(yi)過(guo)(guo)程(cheng)的(de)(de)總和(he)(he)，其他過(guo)(guo)程(cheng)則稱為輔助過(guo)(guo)程(cheng)，例如運輸(shu)、保管、動力供應、設備維修等。除(chu)了(le)要(yao)重視機械(xie)(xie)(xie)加工(gong)(gong)的(de)(de)費用(yong)計(ji)(ji)算(suan)外(wai)，還(huan)要(yao)知(zhi)道應怎樣(yang)進行正確(que)計(ji)(ji)算(suan)，這樣(yang)才能(neng)(neng)得到(dao)準確(que)結(jie)果和(he)(he)正確(que)數(shu)值(zhi)，從而避(bi)免錯誤結(jie)果和(he)(he)得到(dao)錯誤數(shu)值(zhi)。
