機械(xie)加(jia)工廠機器的(de)(de)消費過程是指從(cong)原(yuan)資料(liao)或半(ban)廢品制(zhi)成產(chan)品的(de)(de)全(quan)部過程。對(dui)機器消費而言(yan)包括原(yuan)資料(liao)的(de)(de)運輸和(he)保(bao)管，消費的(de)(de)準備(bei)，毛坯的(de)(de)制(zhi)造，零件的(de)(de)加(jia)工和(he)熱處置，產(chan)品的(de)(de)裝配、及調試，油(you)漆和(he)包裝等內容。

    消(xiao)(xiao)費過(guo)程(cheng)(cheng)的內容非(fei)常普遍，現代企業(ye)用系(xi)統工程(cheng)(cheng)學的原理和辦法組(zu)織(zhi)消(xiao)(xiao)費和指導消(xiao)(xiao)費，將消(xiao)(xiao)費過(guo)程(cheng)(cheng)看成是一個具有輸入和輸出(chu)的消(xiao)(xiao)費系(xi)統。在消(xiao)(xiao)費過(guo)程(cheng)(cheng)中(zhong)，但凡(fan)改動消(xiao)(xiao)費對象(xiang)的外形(xing)、尺寸、位置和性質等，使其成為廢(fei)品(pin)或(huo)者(zhe)半廢(fei)品(pin)的過(guo)程(cheng)(cheng)稱為工藝過(guo)程(cheng)(cheng)。它是消(xiao)(xiao)費過(guo)程(cheng)(cheng)的主要局部(bu)。

    機械(xie)加(jia)工(gong)(gong)(gong)廠工(gong)(gong)(gong)藝(yi)過(guo)(guo)程(cheng)(cheng)(cheng)又可分為(wei)鑄造、鍛造、沖(chong)壓(ya)、焊(han)接、機械(xie)加(jia)工(gong)(gong)(gong)、裝配等工(gong)(gong)(gong)藝(yi)過(guo)(guo)程(cheng)(cheng)(cheng)，機械(xie)制造工(gong)(gong)(gong)藝(yi)過(guo)(guo)程(cheng)(cheng)(cheng)普通是(shi)指零件的(de)機械(xie)加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)過(guo)(guo)程(cheng)(cheng)(cheng)和(he)(he)機器(qi)的(de)裝配工(gong)(gong)(gong)藝(yi)過(guo)(guo)程(cheng)(cheng)(cheng)的(de)總和(he)(he)，其他過(guo)(guo)程(cheng)(cheng)(cheng)則稱為(wei)輔助(zhu)過(guo)(guo)程(cheng)(cheng)(cheng)，例如運輸、保(bao)管(guan)、動(dong)力供給(gei)、設備維(wei)修等。工(gong)(gong)(gong)藝(yi)過(guo)(guo)程(cheng)(cheng)(cheng)又是(shi)由一個或(huo)若干(gan)個次第排列(lie)的(de)工(gong)(gong)(gong)序(xu)組(zu)成(cheng)的(de)，一個工(gong)(gong)(gong)序(xu)由有(you)若干(gan)個工(gong)(gong)(gong)步組(zu)成(cheng)。工(gong)(gong)(gong)序(xu)是(shi)組(zu)成(cheng)機械(xie)加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)過(guo)(guo)程(cheng)(cheng)(cheng)的(de)根本單元。

    所謂(wei)工序(xu)是(shi)指一(yi)(yi)個(ge)或(huo)一(yi)(yi)組工人，在一(yi)(yi)臺機床上或(huo)一(yi)(yi)個(ge)工作地(di)點，對(dui)同(tong)一(yi)(yi)工件或(huo)同(tong)時對(dui)幾個(ge)工件所連續(xu)完成(cheng)的(de)那一(yi)(yi)局部(bu)工藝(yi)過程。構成(cheng)一(yi)(yi)個(ge)工序(xu)的(de)主要(yao)特性是(shi)不改動(dong)加工對(dui)象、設備和操作者，而且工序(xu)的(de)內容(rong)是(shi)連續(xu)完成(cheng)的(de)。
