 ;如何進行機(ji)械(xie)加工(gong)(gong)工(gong)(gong)序(xu)(xu)的設計？東莞機(ji)械(xie)加工(gong)(gong)工(gong)(gong)序(xu)(xu)的定(ding)義是(shi)什么？很(hen)多機(ji)械(xie)加工(gong)(gong)廠廠家(jia)都會(hui)有這(zhe)樣一(yi)個問題(ti)，對(dui)機(ji)械(xie)加工(gong)(gong)工(gong)(gong)序(xu)(xu)有自己的理解(jie)。所謂(wei)機(ji)械(xie)加工(gong)(gong)工(gong)(gong)序(xu)(xu)是(shi)指完成一(yi)個工(gong)(gong)件，所需要的步驟(zou)。這(zhe)個步驟(zou)可(ke)以(yi)是(shi)由單(dan)獨一(yi)個人(ren)完成的，也(ye)(ye)可(ke)以(yi)是(shi)有很(hen)多人(ren)共同完成的；工(gong)(gong)件可(ke)以(yi)是(shi)一(yi)個，也(ye)(ye)可(ke)以(yi)的多個。
如(ru)何設(she)計機械(xie)加工工序(xu)，這是每個廠家必須(xu)面臨(lin)的(de)問題。不(bu)同(tong)(tong)(tong)的(de)生(sheng)產設(she)備(bei)，不(bu)同(tong)(tong)(tong)的(de)生(sheng)產規模，不(bu)同(tong)(tong)(tong)的(de)生(sheng)產條件，不(bu)同(tong)(tong)(tong)的(de)人(ren)員配備(bei)，所設(she)計的(de)工藝也不(bu)盡相(xiang)同(tong)(tong)(tong)。但是原理是相(xiang)通的(de)，
    一般，單(dan)件(jian)產品，可(ke)交由師傅，自己全權處(chu)(chu)理；大(da)(da)批量(liang)零件(jian)，必須(xu)由專人(ren)下料，開粗(cu)，粗(cu)加(jia)(jia)工(gong)和(he)精(jing)加(jia)(jia)工(gong)才可(ke)以(yi)快(kuai)速有效的(de)生產。為(wei)(wei)了保(bao)證加(jia)(jia)工(gong)精(jing)度，粗(cu)、精(jing)加(jia)(jia)工(gong)最(zui)好分開進(jin)行(xing)。因為(wei)(wei)粗(cu)加(jia)(jia)工(gong)時，切削量(liang)大(da)(da)，工(gong)件(jian)所(suo)受切削力、夾緊力大(da)(da)，發(fa)熱量(liang)多，以(yi)及(ji)加(jia)(jia)工(gong)表面有較顯著的(de)加(jia)(jia)工(gong)硬化現(xian)象，工(gong)件(jian)內(nei)部存在(zai)著較大(da)(da)的(de)內(nei)應力，如果粗(cu)、粗(cu)加(jia)(jia)工(gong)連續進(jin)行(xing)，則精(jing)加(jia)(jia)工(gong)后(hou)的(de)零件(jian)精(jing)度會因為(wei)(wei)應力的(de)重新(xin)分布(bu)而很(hen)快(kuai)喪失。對于某些加(jia)(jia)工(gong)精(jing)度要求高(gao)的(de)零件(jian)。在(zai)粗(cu)加(jia)(jia)工(gong)之(zhi)后(hou)和(he)精(jing)加(jia)(jia)工(gong)之(zhi)前(qian)，還(huan)應安排低溫(wen)退火或時效處(chu)(chu)理工(gong)序來消除內(nei)應力。
