 如何進行機械(xie)(xie)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)序(xu)的設計？東莞(guan)機械(xie)(xie)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)序(xu)的定義是什(shen)么？很多(duo)(duo)機械(xie)(xie)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)廠廠家都會有這樣一個問題(ti)，對(dui)機械(xie)(xie)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)序(xu)有自己的理解。所謂機械(xie)(xie)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)序(xu)是指完成(cheng)一個工(gong)(gong)(gong)(gong)件(jian)，所需要的步(bu)驟。這個步(bu)驟可以(yi)(yi)是由(you)單獨一個人完成(cheng)的，也(ye)可以(yi)(yi)是有很多(duo)(duo)人共同完成(cheng)的；工(gong)(gong)(gong)(gong)件(jian)可以(yi)(yi)是一個，也(ye)可以(yi)(yi)的多(duo)(duo)個。
如何設(she)計機械加(jia)工工序，這(zhe)是(shi)每個廠家必(bi)須面臨的(de)問題(ti)。不同的(de)生產設(she)備(bei)，不同的(de)生產規模(mo)，不同的(de)生產條件(jian)，不同的(de)人員(yuan)配備(bei)，所設(she)計的(de)工藝也不盡(jin)相同。但(dan)是(shi)原理是(shi)相通(tong)的(de)，
    一般，單件(jian)產(chan)品(pin)，可(ke)(ke)交由師傅，自己全權處理；大批量(liang)(liang)零(ling)件(jian)，必須由專人下料，開粗(cu)(cu)，粗(cu)(cu)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)和精加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)才可(ke)(ke)以快速有(you)效的(de)(de)(de)(de)生產(chan)。為(wei)了(le)保證加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)精度(du)，粗(cu)(cu)、精加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)最好分(fen)開進(jin)行。因(yin)為(wei)粗(cu)(cu)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)時，切(qie)(qie)削量(liang)(liang)大，工(gong)(gong)(gong)(gong)件(jian)所受(shou)切(qie)(qie)削力(li)(li)(li)、夾緊力(li)(li)(li)大，發熱量(liang)(liang)多，以及加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)表面有(you)較顯著(zhu)的(de)(de)(de)(de)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)硬化現象，工(gong)(gong)(gong)(gong)件(jian)內部存在著(zhu)較大的(de)(de)(de)(de)內應(ying)力(li)(li)(li)，如果粗(cu)(cu)、粗(cu)(cu)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)連續(xu)進(jin)行，則精加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)后的(de)(de)(de)(de)零(ling)件(jian)精度(du)會因(yin)為(wei)應(ying)力(li)(li)(li)的(de)(de)(de)(de)重新分(fen)布(bu)而很快喪失。對于某些(xie)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)精度(du)要求高的(de)(de)(de)(de)零(ling)件(jian)。在粗(cu)(cu)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)之后和精加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)之前(qian)，還應(ying)安(an)排低(di)溫退火或時效處理工(gong)(gong)(gong)(gong)序來(lai)消除(chu)內應(ying)力(li)(li)(li)。
