 如何進行機(ji)械加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)序(xu)的(de)設計？東莞(guan)機(ji)械加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)序(xu)的(de)定(ding)義(yi)是(shi)什么？很(hen)多(duo)機(ji)械加(jia)工(gong)(gong)(gong)廠(chang)(chang)廠(chang)(chang)家都會有這樣一(yi)個問(wen)題，對機(ji)械加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)序(xu)有自己(ji)的(de)理(li)解。所謂(wei)機(ji)械加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)序(xu)是(shi)指完成(cheng)一(yi)個工(gong)(gong)(gong)件，所需(xu)要的(de)步驟。這個步驟可(ke)(ke)以(yi)是(shi)由單獨一(yi)個人完成(cheng)的(de)，也可(ke)(ke)以(yi)是(shi)有很(hen)多(duo)人共(gong)同完成(cheng)的(de)；工(gong)(gong)(gong)件可(ke)(ke)以(yi)是(shi)一(yi)個，也可(ke)(ke)以(yi)的(de)多(duo)個。
如何設(she)計機械(xie)加工(gong)工(gong)序，這是每個廠(chang)家(jia)必須面臨的(de)問(wen)題。不同的(de)生(sheng)產設(she)備(bei)，不同的(de)生(sheng)產規模，不同的(de)生(sheng)產條件(jian)，不同的(de)人(ren)員配備(bei)，所設(she)計的(de)工(gong)藝也不盡相(xiang)(xiang)同。但是原理是相(xiang)(xiang)通的(de)，
    一般，單(dan)件產品，可交由(you)師傅，自己全權(quan)處理(li)；大批(pi)量零件，必須(xu)由(you)專人下料，開粗(cu)，粗(cu)加(jia)(jia)(jia)工(gong)(gong)(gong)和(he)精(jing)加(jia)(jia)(jia)工(gong)(gong)(gong)才可以(yi)快速有(you)(you)效(xiao)的(de)(de)生產。為了(le)保證加(jia)(jia)(jia)工(gong)(gong)(gong)精(jing)度，粗(cu)、精(jing)加(jia)(jia)(jia)工(gong)(gong)(gong)最好分(fen)(fen)開進行。因(yin)為粗(cu)加(jia)(jia)(jia)工(gong)(gong)(gong)時，切削(xue)量大，工(gong)(gong)(gong)件所受切削(xue)力(li)(li)、夾(jia)緊力(li)(li)大，發熱量多，以(yi)及(ji)加(jia)(jia)(jia)工(gong)(gong)(gong)表面有(you)(you)較顯著的(de)(de)加(jia)(jia)(jia)工(gong)(gong)(gong)硬化現象，工(gong)(gong)(gong)件內(nei)(nei)部存(cun)在(zai)著較大的(de)(de)內(nei)(nei)應(ying)力(li)(li)，如果粗(cu)、粗(cu)加(jia)(jia)(jia)工(gong)(gong)(gong)連續進行，則精(jing)加(jia)(jia)(jia)工(gong)(gong)(gong)后的(de)(de)零件精(jing)度會因(yin)為應(ying)力(li)(li)的(de)(de)重新分(fen)(fen)布而很(hen)快喪失。對于某些加(jia)(jia)(jia)工(gong)(gong)(gong)精(jing)度要(yao)求高的(de)(de)零件。在(zai)粗(cu)加(jia)(jia)(jia)工(gong)(gong)(gong)之后和(he)精(jing)加(jia)(jia)(jia)工(gong)(gong)(gong)之前，還應(ying)安(an)排低溫退火或(huo)時效(xiao)處理(li)工(gong)(gong)(gong)序來消除內(nei)(nei)應(ying)力(li)(li)。
