 如(ru)何進(jin)行機(ji)械(xie)(xie)(xie)加工(gong)(gong)(gong)工(gong)(gong)(gong)序(xu)(xu)的(de)設計(ji)？東莞(guan)機(ji)械(xie)(xie)(xie)加工(gong)(gong)(gong)工(gong)(gong)(gong)序(xu)(xu)的(de)定義是什么(me)？很(hen)(hen)多機(ji)械(xie)(xie)(xie)加工(gong)(gong)(gong)廠廠家都會有這(zhe)樣一(yi)個問題，對機(ji)械(xie)(xie)(xie)加工(gong)(gong)(gong)工(gong)(gong)(gong)序(xu)(xu)有自己的(de)理解。所(suo)謂機(ji)械(xie)(xie)(xie)加工(gong)(gong)(gong)工(gong)(gong)(gong)序(xu)(xu)是指完成(cheng)(cheng)一(yi)個工(gong)(gong)(gong)件，所(suo)需要的(de)步(bu)驟。這(zhe)個步(bu)驟可以(yi)是由單(dan)獨一(yi)個人完成(cheng)(cheng)的(de)，也可以(yi)是有很(hen)(hen)多人共同完成(cheng)(cheng)的(de)；工(gong)(gong)(gong)件可以(yi)是一(yi)個，也可以(yi)的(de)多個。
如何(he)設計機械加工(gong)工(gong)序，這(zhe)是每個(ge)廠家必須面臨(lin)的(de)(de)問題。不同(tong)的(de)(de)生產(chan)設備(bei)，不同(tong)的(de)(de)生產(chan)規模(mo)，不同(tong)的(de)(de)生產(chan)條件，不同(tong)的(de)(de)人(ren)員配(pei)備(bei)，所(suo)設計的(de)(de)工(gong)藝也(ye)不盡相同(tong)。但(dan)是原理(li)是相通的(de)(de)，
    一般(ban)，單件(jian)(jian)(jian)產(chan)(chan)品，可交由(you)師傅，自己(ji)全權處理；大(da)批(pi)量零(ling)(ling)件(jian)(jian)(jian)，必須由(you)專人(ren)下(xia)料，開粗(cu)(cu)(cu)，粗(cu)(cu)(cu)加(jia)工(gong)(gong)和精(jing)(jing)加(jia)工(gong)(gong)才可以快(kuai)速有效的(de)(de)生產(chan)(chan)。為了保證加(jia)工(gong)(gong)精(jing)(jing)度(du)(du)，粗(cu)(cu)(cu)、精(jing)(jing)加(jia)工(gong)(gong)最好分開進行。因(yin)為粗(cu)(cu)(cu)加(jia)工(gong)(gong)時(shi)，切削量大(da)，工(gong)(gong)件(jian)(jian)(jian)所受切削力、夾(jia)緊(jin)力大(da)，發熱量多，以及加(jia)工(gong)(gong)表面(mian)有較(jiao)顯(xian)著的(de)(de)加(jia)工(gong)(gong)硬化現象(xiang)，工(gong)(gong)件(jian)(jian)(jian)內(nei)部存在著較(jiao)大(da)的(de)(de)內(nei)應力，如果(guo)粗(cu)(cu)(cu)、粗(cu)(cu)(cu)加(jia)工(gong)(gong)連續進行，則(ze)精(jing)(jing)加(jia)工(gong)(gong)后(hou)的(de)(de)零(ling)(ling)件(jian)(jian)(jian)精(jing)(jing)度(du)(du)會因(yin)為應力的(de)(de)重新分布而很快(kuai)喪失(shi)。對于某些加(jia)工(gong)(gong)精(jing)(jing)度(du)(du)要求高的(de)(de)零(ling)(ling)件(jian)(jian)(jian)。在粗(cu)(cu)(cu)加(jia)工(gong)(gong)之后(hou)和精(jing)(jing)加(jia)工(gong)(gong)之前，還應安排低溫退(tui)火或時(shi)效處理工(gong)(gong)序來消除內(nei)應力。
