 如何(he)進行(xing)機械(xie)加工(gong)(gong)(gong)工(gong)(gong)(gong)序(xu)(xu)的設(she)計？東莞機械(xie)加工(gong)(gong)(gong)工(gong)(gong)(gong)序(xu)(xu)的定義是(shi)什么？很(hen)多機械(xie)加工(gong)(gong)(gong)廠(chang)廠(chang)家都會有這(zhe)樣一(yi)個(ge)問題，對機械(xie)加工(gong)(gong)(gong)工(gong)(gong)(gong)序(xu)(xu)有自己的理(li)解。所(suo)謂機械(xie)加工(gong)(gong)(gong)工(gong)(gong)(gong)序(xu)(xu)是(shi)指(zhi)完成一(yi)個(ge)工(gong)(gong)(gong)件，所(suo)需要的步(bu)驟(zou)。這(zhe)個(ge)步(bu)驟(zou)可以(yi)(yi)是(shi)由單獨(du)一(yi)個(ge)人完成的，也可以(yi)(yi)是(shi)有很(hen)多人共(gong)同完成的；工(gong)(gong)(gong)件可以(yi)(yi)是(shi)一(yi)個(ge)，也可以(yi)(yi)的多個(ge)。
如何設計機械加工(gong)工(gong)序，這是(shi)(shi)每個(ge)廠家必(bi)須面(mian)臨的問題。不同(tong)的生產設備，不同(tong)的生產規(gui)模，不同(tong)的生產條(tiao)件，不同(tong)的人員配(pei)備，所設計的工(gong)藝(yi)也(ye)不盡相同(tong)。但是(shi)(shi)原理是(shi)(shi)相通(tong)的，
    一般，單件(jian)產(chan)品(pin)，可(ke)交由(you)師傅，自己全權(quan)處理(li)；大批量零件(jian)，必須由(you)專人(ren)下料，開粗(cu)(cu)(cu)，粗(cu)(cu)(cu)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)和(he)精(jing)(jing)(jing)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)才可(ke)以(yi)快速有效的(de)(de)生產(chan)。為(wei)了保證加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)精(jing)(jing)(jing)度，粗(cu)(cu)(cu)、精(jing)(jing)(jing)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)最好分開進(jin)行(xing)。因為(wei)粗(cu)(cu)(cu)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)時，切(qie)(qie)削量大，工(gong)(gong)(gong)(gong)(gong)件(jian)所受切(qie)(qie)削力(li)、夾緊力(li)大，發(fa)熱(re)量多，以(yi)及加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)表面有較顯著(zhu)的(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)硬化現象，工(gong)(gong)(gong)(gong)(gong)件(jian)內部存在著(zhu)較大的(de)(de)內應(ying)力(li)，如果粗(cu)(cu)(cu)、粗(cu)(cu)(cu)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)連續進(jin)行(xing)，則精(jing)(jing)(jing)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)后的(de)(de)零件(jian)精(jing)(jing)(jing)度會(hui)因為(wei)應(ying)力(li)的(de)(de)重新分布而很快喪失。對(dui)于某些加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)精(jing)(jing)(jing)度要求(qiu)高的(de)(de)零件(jian)。在粗(cu)(cu)(cu)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)之后和(he)精(jing)(jing)(jing)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)之前(qian)，還應(ying)安排(pai)低溫(wen)退火(huo)或(huo)時效處理(li)工(gong)(gong)(gong)(gong)(gong)序來消除內應(ying)力(li)。
