 如(ru)何進行機(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)序的(de)設計？東莞機(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)序的(de)定義(yi)是(shi)什么？很多機(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)廠(chang)廠(chang)家都會有這樣一個問題，對機(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)序有自己的(de)理解(jie)。所謂機(ji)械(xie)加(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)序是(shi)指(zhi)完(wan)(wan)成(cheng)(cheng)一個工(gong)(gong)(gong)件(jian)(jian)，所需要的(de)步(bu)驟。這個步(bu)驟可(ke)(ke)以是(shi)由單獨一個人完(wan)(wan)成(cheng)(cheng)的(de)，也(ye)可(ke)(ke)以是(shi)有很多人共同完(wan)(wan)成(cheng)(cheng)的(de)；工(gong)(gong)(gong)件(jian)(jian)可(ke)(ke)以是(shi)一個，也(ye)可(ke)(ke)以的(de)多個。
如(ru)何設(she)計機械加工工序(xu)，這(zhe)是每個廠家必須面臨的(de)(de)問題(ti)。不(bu)同(tong)的(de)(de)生產(chan)設(she)備，不(bu)同(tong)的(de)(de)生產(chan)規模，不(bu)同(tong)的(de)(de)生產(chan)條件，不(bu)同(tong)的(de)(de)人員(yuan)配備，所設(she)計的(de)(de)工藝(yi)也不(bu)盡相(xiang)同(tong)。但是原(yuan)理是相(xiang)通(tong)的(de)(de)，
    一般，單(dan)件(jian)(jian)產品，可交(jiao)由師傅(fu)，自己(ji)全權(quan)處理；大(da)批(pi)量零件(jian)(jian)，必(bi)須由專人(ren)下料，開(kai)(kai)粗(cu)，粗(cu)加(jia)(jia)(jia)工(gong)(gong)和(he)精(jing)加(jia)(jia)(jia)工(gong)(gong)才可以快(kuai)速(su)有效的(de)生產。為(wei)了保證加(jia)(jia)(jia)工(gong)(gong)精(jing)度(du)，粗(cu)、精(jing)加(jia)(jia)(jia)工(gong)(gong)最好分(fen)開(kai)(kai)進(jin)行(xing)。因為(wei)粗(cu)加(jia)(jia)(jia)工(gong)(gong)時，切削量大(da)，工(gong)(gong)件(jian)(jian)所受切削力(li)、夾(jia)緊力(li)大(da)，發熱量多，以及加(jia)(jia)(jia)工(gong)(gong)表面有較(jiao)顯(xian)著的(de)加(jia)(jia)(jia)工(gong)(gong)硬化(hua)現象(xiang)，工(gong)(gong)件(jian)(jian)內部(bu)存(cun)在(zai)著較(jiao)大(da)的(de)內應(ying)力(li)，如果粗(cu)、粗(cu)加(jia)(jia)(jia)工(gong)(gong)連(lian)續進(jin)行(xing)，則(ze)精(jing)加(jia)(jia)(jia)工(gong)(gong)后的(de)零件(jian)(jian)精(jing)度(du)會因為(wei)應(ying)力(li)的(de)重新分(fen)布而很(hen)快(kuai)喪失。對于(yu)某(mou)些(xie)加(jia)(jia)(jia)工(gong)(gong)精(jing)度(du)要求高的(de)零件(jian)(jian)。在(zai)粗(cu)加(jia)(jia)(jia)工(gong)(gong)之后和(he)精(jing)加(jia)(jia)(jia)工(gong)(gong)之前(qian)，還應(ying)安排低溫退火或時效處理工(gong)(gong)序來(lai)消(xiao)除內應(ying)力(li)。
