 如何進行機(ji)(ji)械(xie)加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)序(xu)的設計？東莞機(ji)(ji)械(xie)加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)序(xu)的定義是(shi)(shi)什么？很多(duo)機(ji)(ji)械(xie)加(jia)工(gong)(gong)(gong)廠廠家都(dou)會有這樣一個(ge)(ge)問題，對(dui)機(ji)(ji)械(xie)加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)序(xu)有自(zi)己的理解。所謂機(ji)(ji)械(xie)加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)序(xu)是(shi)(shi)指完成(cheng)一個(ge)(ge)工(gong)(gong)(gong)件(jian)，所需要的步驟。這個(ge)(ge)步驟可以(yi)是(shi)(shi)由單(dan)獨(du)一個(ge)(ge)人完成(cheng)的，也(ye)可以(yi)是(shi)(shi)有很多(duo)人共同完成(cheng)的；工(gong)(gong)(gong)件(jian)可以(yi)是(shi)(shi)一個(ge)(ge)，也(ye)可以(yi)的多(duo)個(ge)(ge)。
如何設(she)計機械加工工序，這(zhe)是(shi)每個廠家必須面臨(lin)的(de)問題。不(bu)(bu)同(tong)(tong)的(de)生(sheng)產(chan)(chan)設(she)備，不(bu)(bu)同(tong)(tong)的(de)生(sheng)產(chan)(chan)規模，不(bu)(bu)同(tong)(tong)的(de)生(sheng)產(chan)(chan)條(tiao)件，不(bu)(bu)同(tong)(tong)的(de)人員配備，所設(she)計的(de)工藝也不(bu)(bu)盡相同(tong)(tong)。但是(shi)原(yuan)理是(shi)相通的(de)，
    一般(ban)，單件(jian)產品(pin)，可(ke)交由(you)師傅(fu)，自己(ji)全權處理(li)；大(da)批(pi)量零(ling)件(jian)，必(bi)須由(you)專人下料，開粗(cu)，粗(cu)加(jia)(jia)工(gong)(gong)(gong)和精(jing)加(jia)(jia)工(gong)(gong)(gong)才可(ke)以(yi)快速(su)有效(xiao)的(de)生產。為了保(bao)證加(jia)(jia)工(gong)(gong)(gong)精(jing)度(du)，粗(cu)、精(jing)加(jia)(jia)工(gong)(gong)(gong)最好分開進(jin)行(xing)。因為粗(cu)加(jia)(jia)工(gong)(gong)(gong)時，切(qie)削量大(da)，工(gong)(gong)(gong)件(jian)所受切(qie)削力、夾緊力大(da)，發(fa)熱量多，以(yi)及加(jia)(jia)工(gong)(gong)(gong)表面有較顯著(zhu)的(de)加(jia)(jia)工(gong)(gong)(gong)硬化現象，工(gong)(gong)(gong)件(jian)內部存在著(zhu)較大(da)的(de)內應力，如果粗(cu)、粗(cu)加(jia)(jia)工(gong)(gong)(gong)連續進(jin)行(xing)，則精(jing)加(jia)(jia)工(gong)(gong)(gong)后(hou)的(de)零(ling)件(jian)精(jing)度(du)會(hui)因為應力的(de)重新分布而很快喪(sang)失(shi)。對于某些加(jia)(jia)工(gong)(gong)(gong)精(jing)度(du)要求(qiu)高的(de)零(ling)件(jian)。在粗(cu)加(jia)(jia)工(gong)(gong)(gong)之(zhi)后(hou)和精(jing)加(jia)(jia)工(gong)(gong)(gong)之(zhi)前，還應安排(pai)低溫退火或時效(xiao)處理(li)工(gong)(gong)(gong)序來消除內應力。
