機器的生產過程是指從原材料(或半成品)制成產品的全部過程。對機器生產而言包括原材料的運輸和保存，生產的準備，毛坯的制造，零件的加工和熱處理，產品的裝配、及調試，油漆和包裝等內容。生產過程的內容十分廣泛，現代企業用系統工程學的原理和方法組織生產和指導生產，將生產過程看成是一個具有輸入和輸出的生產系統。天津機械加工。

在(zai)生(sheng)(sheng)產(chan)過(guo)(guo)(guo)程(cheng)(cheng)(cheng)(cheng)中，凡是改變生(sheng)(sheng)產(chan)對象的(de)(de)形狀(zhuang)、尺寸(cun)、位(wei)置(zhi)和性質等(deng)，使其成(cheng)(cheng)為成(cheng)(cheng)品(pin)或者半成(cheng)(cheng)品(pin)的(de)(de)過(guo)(guo)(guo)程(cheng)(cheng)(cheng)(cheng)稱為工(gong)(gong)(gong)藝(yi)(yi)過(guo)(guo)(guo)程(cheng)(cheng)(cheng)(cheng)。它(ta)是生(sheng)(sheng)產(chan)過(guo)(guo)(guo)程(cheng)(cheng)(cheng)(cheng)的(de)(de)主要部分。工(gong)(gong)(gong)藝(yi)(yi)過(guo)(guo)(guo)程(cheng)(cheng)(cheng)(cheng)又可分為鑄造(zao)、鍛造(zao)、沖壓、焊接、機械加工(gong)(gong)(gong)、裝配(pei)(pei)等(deng)工(gong)(gong)(gong)藝(yi)(yi)過(guo)(guo)(guo)程(cheng)(cheng)(cheng)(cheng)，機械制(zhi)造(zao)工(gong)(gong)(gong)藝(yi)(yi)過(guo)(guo)(guo)程(cheng)(cheng)(cheng)(cheng)一般是指零件的(de)(de)機械加工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)(yi)過(guo)(guo)(guo)程(cheng)(cheng)(cheng)(cheng)和機器的(de)(de)裝配(pei)(pei)工(gong)(gong)(gong)藝(yi)(yi)過(guo)(guo)(guo)程(cheng)(cheng)(cheng)(cheng)的(de)(de)總和，其他過(guo)(guo)(guo)程(cheng)(cheng)(cheng)(cheng)則稱為輔助(zhu)過(guo)(guo)(guo)程(cheng)(cheng)(cheng)(cheng)，例如運輸、保管、動力供應、設備維修等(deng)。工(gong)(gong)(gong)藝(yi)(yi)過(guo)(guo)(guo)程(cheng)(cheng)(cheng)(cheng)又是由一個或若(ruo)干(gan)(gan)個順序排(pai)列的(de)(de)工(gong)(gong)(gong)序組成(cheng)(cheng)的(de)(de)，一個工(gong)(gong)(gong)序由有若(ruo)干(gan)(gan)個工(gong)(gong)(gong)步組成(cheng)(cheng)。

工序是組成機械加工工藝過程的基本單元。所謂工序是指一個(或一組)工人，在一臺機床上(或一個工作地點)，對同一工件(或同時對幾個工件)所連續完成的那一部分工藝過程。構成一個工序的主要特點是不改變加工對象、設備和操作者，而且工序的內容是連續完成的。天津機械加工。

工(gong)步是在加工(gong)表面不(bu)變(bian)、加工(gong)工(gong)具不(bu)變(bian)、切削用量(liang)不(bu)變(bian)的條件下

走刀又叫工作行程，是加(jia)工工具在加(jia)工表面(mian)上加(jia)工一次所完(wan)成的工步。

制定機械(xie)加(jia)工(gong)(gong)工(gong)(gong)藝(yi)過程，必 須確定該工(gong)(gong)件要經過幾(ji)道工(gong)(gong)序(xu)(xu)以及(ji)工(gong)(gong)序(xu)(xu)進行的先后順序(xu)(xu)，僅列出主要工(gong)(gong)序(xu)(xu)名(ming)稱(cheng)及(ji)其加(jia)工(gong)(gong)順序(xu)(xu)的簡略工(gong)(gong)藝(yi)過程，稱(cheng)為工(gong)(gong)藝(yi)路線。

工(gong)(gong)(gong)藝路線的(de)(de)擬(ni)定(ding)是制定(ding)工(gong)(gong)(gong)藝過程(cheng)的(de)(de)總體布局(ju)，主要(yao)任務是選擇各(ge)個表(biao)(biao)面(mian)的(de)(de)加工(gong)(gong)(gong)方法，確定(ding)各(ge)個表(biao)(biao)面(mian)的(de)(de)加工(gong)(gong)(gong)順序，以及整個工(gong)(gong)(gong)藝過程(cheng)中工(gong)(gong)(gong)序數目的(de)(de)多少(shao)等。工(gong)(gong)(gong)藝路線擬(ni)定(ding)須遵循一定(ding)的(de)(de)原則。
