 如何進行機(ji)(ji)械加(jia)(jia)(jia)工(gong)(gong)工(gong)(gong)序(xu)(xu)(xu)的設計？東(dong)莞機(ji)(ji)械加(jia)(jia)(jia)工(gong)(gong)工(gong)(gong)序(xu)(xu)(xu)的定義是什么？很多(duo)(duo)機(ji)(ji)械加(jia)(jia)(jia)工(gong)(gong)廠廠家都會有這樣一(yi)個(ge)(ge)問題，對機(ji)(ji)械加(jia)(jia)(jia)工(gong)(gong)工(gong)(gong)序(xu)(xu)(xu)有自己的理解(jie)。所謂機(ji)(ji)械加(jia)(jia)(jia)工(gong)(gong)工(gong)(gong)序(xu)(xu)(xu)是指完(wan)成一(yi)個(ge)(ge)工(gong)(gong)件，所需要的步(bu)驟。這個(ge)(ge)步(bu)驟可(ke)以(yi)是由(you)單(dan)獨一(yi)個(ge)(ge)人完(wan)成的，也可(ke)以(yi)是有很多(duo)(duo)人共同完(wan)成的；工(gong)(gong)件可(ke)以(yi)是一(yi)個(ge)(ge)，也可(ke)以(yi)的多(duo)(duo)個(ge)(ge)。
如何設計(ji)機械(xie)加(jia)工(gong)工(gong)序(xu)，這是(shi)(shi)每個廠家(jia)必須(xu)面臨的(de)(de)問題。不(bu)(bu)同的(de)(de)生產設備，不(bu)(bu)同的(de)(de)生產規模，不(bu)(bu)同的(de)(de)生產條件(jian)，不(bu)(bu)同的(de)(de)人員配備，所設計(ji)的(de)(de)工(gong)藝也(ye)不(bu)(bu)盡(jin)相(xiang)同。但是(shi)(shi)原(yuan)理(li)是(shi)(shi)相(xiang)通(tong)的(de)(de)，
    一(yi)般(ban)，單(dan)件(jian)(jian)(jian)產品，可交由(you)師傅，自己全(quan)權處(chu)理；大(da)(da)批量(liang)(liang)零(ling)(ling)件(jian)(jian)(jian)，必須由(you)專人下(xia)料，開(kai)粗(cu)(cu)，粗(cu)(cu)加(jia)(jia)(jia)工(gong)(gong)和(he)精加(jia)(jia)(jia)工(gong)(gong)才可以快(kuai)速有效的(de)(de)生產。為(wei)(wei)了保證加(jia)(jia)(jia)工(gong)(gong)精度(du)(du)(du)，粗(cu)(cu)、精加(jia)(jia)(jia)工(gong)(gong)最好分開(kai)進(jin)行。因為(wei)(wei)粗(cu)(cu)加(jia)(jia)(jia)工(gong)(gong)時，切(qie)削(xue)量(liang)(liang)大(da)(da)，工(gong)(gong)件(jian)(jian)(jian)所受(shou)切(qie)削(xue)力(li)、夾(jia)緊力(li)大(da)(da)，發(fa)熱量(liang)(liang)多，以及加(jia)(jia)(jia)工(gong)(gong)表面有較(jiao)顯(xian)著(zhu)(zhu)的(de)(de)加(jia)(jia)(jia)工(gong)(gong)硬化現(xian)象，工(gong)(gong)件(jian)(jian)(jian)內部存在(zai)著(zhu)(zhu)較(jiao)大(da)(da)的(de)(de)內應力(li)，如果粗(cu)(cu)、粗(cu)(cu)加(jia)(jia)(jia)工(gong)(gong)連續進(jin)行，則(ze)精加(jia)(jia)(jia)工(gong)(gong)后(hou)的(de)(de)零(ling)(ling)件(jian)(jian)(jian)精度(du)(du)(du)會因為(wei)(wei)應力(li)的(de)(de)重新分布而很快(kuai)喪失。對于某些加(jia)(jia)(jia)工(gong)(gong)精度(du)(du)(du)要求高的(de)(de)零(ling)(ling)件(jian)(jian)(jian)。在(zai)粗(cu)(cu)加(jia)(jia)(jia)工(gong)(gong)之后(hou)和(he)精加(jia)(jia)(jia)工(gong)(gong)之前(qian)，還(huan)應安排低溫退火或時效處(chu)理工(gong)(gong)序來消除內應力(li)。
