 如何進(jin)行機械加工(gong)(gong)工(gong)(gong)序的(de)設(she)計？東莞機械加工(gong)(gong)工(gong)(gong)序的(de)定義是(shi)(shi)什么？很多(duo)(duo)機械加工(gong)(gong)廠廠家都會(hui)有(you)這(zhe)樣一個問題，對(dui)機械加工(gong)(gong)工(gong)(gong)序有(you)自己(ji)的(de)理解。所(suo)謂機械加工(gong)(gong)工(gong)(gong)序是(shi)(shi)指完(wan)成(cheng)一個工(gong)(gong)件，所(suo)需(xu)要的(de)步驟。這(zhe)個步驟可(ke)(ke)(ke)以(yi)是(shi)(shi)由(you)單獨一個人(ren)完(wan)成(cheng)的(de)，也(ye)可(ke)(ke)(ke)以(yi)是(shi)(shi)有(you)很多(duo)(duo)人(ren)共同完(wan)成(cheng)的(de)；工(gong)(gong)件可(ke)(ke)(ke)以(yi)是(shi)(shi)一個，也(ye)可(ke)(ke)(ke)以(yi)的(de)多(duo)(duo)個。
如何(he)設(she)計(ji)機械加工(gong)工(gong)序，這是每個廠(chang)家必(bi)須面臨的(de)(de)問題。不同的(de)(de)生(sheng)產設(she)備，不同的(de)(de)生(sheng)產規模(mo)，不同的(de)(de)生(sheng)產條(tiao)件，不同的(de)(de)人(ren)員配備，所設(she)計(ji)的(de)(de)工(gong)藝也(ye)不盡相同。但是原理是相通的(de)(de)，
    一般，單件(jian)(jian)產品，可交由(you)師傅，自(zi)己全權處理；大(da)批量零件(jian)(jian)，必須由(you)專人下料，開(kai)粗(cu)，粗(cu)加工(gong)(gong)(gong)(gong)(gong)和(he)精(jing)加工(gong)(gong)(gong)(gong)(gong)才可以快(kuai)速有效的(de)(de)生產。為了保證(zheng)加工(gong)(gong)(gong)(gong)(gong)精(jing)度，粗(cu)、精(jing)加工(gong)(gong)(gong)(gong)(gong)最(zui)好分(fen)開(kai)進(jin)行(xing)。因(yin)為粗(cu)加工(gong)(gong)(gong)(gong)(gong)時，切(qie)削量大(da)，工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)所(suo)受(shou)切(qie)削力(li)(li)、夾緊力(li)(li)大(da)，發熱(re)量多(duo)，以及加工(gong)(gong)(gong)(gong)(gong)表面有較顯著(zhu)的(de)(de)加工(gong)(gong)(gong)(gong)(gong)硬化現(xian)象(xiang)，工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)內(nei)部存在(zai)著(zhu)較大(da)的(de)(de)內(nei)應力(li)(li)，如果(guo)粗(cu)、粗(cu)加工(gong)(gong)(gong)(gong)(gong)連續進(jin)行(xing)，則精(jing)加工(gong)(gong)(gong)(gong)(gong)后(hou)的(de)(de)零件(jian)(jian)精(jing)度會因(yin)為應力(li)(li)的(de)(de)重新(xin)分(fen)布而很快(kuai)喪失。對于某些加工(gong)(gong)(gong)(gong)(gong)精(jing)度要(yao)求高(gao)的(de)(de)零件(jian)(jian)。在(zai)粗(cu)加工(gong)(gong)(gong)(gong)(gong)之后(hou)和(he)精(jing)加工(gong)(gong)(gong)(gong)(gong)之前，還(huan)應安排(pai)低溫退火或時效處理工(gong)(gong)(gong)(gong)(gong)序(xu)來消除內(nei)應力(li)(li)。
