 如何(he)進(jin)行(xing)機械(xie)加工(gong)(gong)工(gong)(gong)序的(de)(de)(de)設(she)計(ji)？東莞(guan)機械(xie)加工(gong)(gong)工(gong)(gong)序的(de)(de)(de)定義是(shi)什么？很多機械(xie)加工(gong)(gong)廠(chang)廠(chang)家都會有這樣一(yi)個(ge)問題，對機械(xie)加工(gong)(gong)工(gong)(gong)序有自己的(de)(de)(de)理解。所(suo)謂(wei)機械(xie)加工(gong)(gong)工(gong)(gong)序是(shi)指完成(cheng)一(yi)個(ge)工(gong)(gong)件(jian)，所(suo)需要的(de)(de)(de)步(bu)驟(zou)。這個(ge)步(bu)驟(zou)可(ke)以(yi)(yi)是(shi)由單獨(du)一(yi)個(ge)人(ren)完成(cheng)的(de)(de)(de)，也(ye)可(ke)以(yi)(yi)是(shi)有很多人(ren)共同完成(cheng)的(de)(de)(de)；工(gong)(gong)件(jian)可(ke)以(yi)(yi)是(shi)一(yi)個(ge)，也(ye)可(ke)以(yi)(yi)的(de)(de)(de)多個(ge)。
如(ru)何設(she)計機械(xie)加工(gong)(gong)工(gong)(gong)序(xu)，這是(shi)每(mei)個廠家必須面臨(lin)的(de)問題(ti)。不(bu)同(tong)(tong)的(de)生(sheng)產(chan)設(she)備，不(bu)同(tong)(tong)的(de)生(sheng)產(chan)規模，不(bu)同(tong)(tong)的(de)生(sheng)產(chan)條件，不(bu)同(tong)(tong)的(de)人員(yuan)配(pei)備，所設(she)計的(de)工(gong)(gong)藝也不(bu)盡相同(tong)(tong)。但是(shi)原理是(shi)相通的(de)，
    一般，單件產品，可交(jiao)由師傅(fu)，自己全(quan)權處(chu)理；大(da)批量(liang)零(ling)件，必須由專人(ren)下料，開(kai)粗(cu)(cu)，粗(cu)(cu)加(jia)工(gong)(gong)(gong)(gong)和精(jing)(jing)(jing)加(jia)工(gong)(gong)(gong)(gong)才可以快速(su)有(you)效(xiao)的(de)生產。為(wei)了保(bao)證加(jia)工(gong)(gong)(gong)(gong)精(jing)(jing)(jing)度，粗(cu)(cu)、精(jing)(jing)(jing)加(jia)工(gong)(gong)(gong)(gong)最好分開(kai)進行。因為(wei)粗(cu)(cu)加(jia)工(gong)(gong)(gong)(gong)時，切削量(liang)大(da)，工(gong)(gong)(gong)(gong)件所受切削力(li)(li)、夾緊力(li)(li)大(da)，發(fa)熱量(liang)多，以及加(jia)工(gong)(gong)(gong)(gong)表面有(you)較顯著(zhu)的(de)加(jia)工(gong)(gong)(gong)(gong)硬化現象，工(gong)(gong)(gong)(gong)件內(nei)部存在著(zhu)較大(da)的(de)內(nei)應力(li)(li)，如果粗(cu)(cu)、粗(cu)(cu)加(jia)工(gong)(gong)(gong)(gong)連續進行，則精(jing)(jing)(jing)加(jia)工(gong)(gong)(gong)(gong)后的(de)零(ling)件精(jing)(jing)(jing)度會因為(wei)應力(li)(li)的(de)重新分布而很快喪(sang)失。對于某些加(jia)工(gong)(gong)(gong)(gong)精(jing)(jing)(jing)度要求高(gao)的(de)零(ling)件。在粗(cu)(cu)加(jia)工(gong)(gong)(gong)(gong)之后和精(jing)(jing)(jing)加(jia)工(gong)(gong)(gong)(gong)之前，還應安排低(di)溫退(tui)火(huo)或時效(xiao)處(chu)理工(gong)(gong)(gong)(gong)序來消(xiao)除(chu)內(nei)應力(li)(li)。
