 如何進行機械加工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)序(xu)的(de)(de)(de)設(she)計？東莞機械加工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)序(xu)的(de)(de)(de)定義是(shi)(shi)什么？很多(duo)機械加工(gong)(gong)(gong)(gong)廠廠家都會(hui)有這樣一(yi)個(ge)(ge)問題，對機械加工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)序(xu)有自己的(de)(de)(de)理解。所謂機械加工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)序(xu)是(shi)(shi)指完(wan)成一(yi)個(ge)(ge)工(gong)(gong)(gong)(gong)件，所需要的(de)(de)(de)步驟。這個(ge)(ge)步驟可(ke)以是(shi)(shi)由單獨一(yi)個(ge)(ge)人完(wan)成的(de)(de)(de)，也可(ke)以是(shi)(shi)有很多(duo)人共同完(wan)成的(de)(de)(de)；工(gong)(gong)(gong)(gong)件可(ke)以是(shi)(shi)一(yi)個(ge)(ge)，也可(ke)以的(de)(de)(de)多(duo)個(ge)(ge)。
如何(he)設(she)計機(ji)械加工工序，這是每個廠家必須(xu)面臨(lin)的(de)(de)問(wen)題。不(bu)(bu)同的(de)(de)生產(chan)設(she)備(bei)，不(bu)(bu)同的(de)(de)生產(chan)規模，不(bu)(bu)同的(de)(de)生產(chan)條件，不(bu)(bu)同的(de)(de)人員配備(bei)，所設(she)計的(de)(de)工藝也不(bu)(bu)盡相(xiang)同。但是原理是相(xiang)通的(de)(de)，
    一般，單件(jian)產品，可交由師傅，自己(ji)全權(quan)處理；大批量零件(jian)，必須(xu)由專人下料，開(kai)粗，粗加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)和精(jing)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)才可以快(kuai)速有效的(de)生產。為了(le)保證加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)精(jing)度，粗、精(jing)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)最(zui)好分開(kai)進行(xing)(xing)。因為粗加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)時，切削(xue)量大，工(gong)(gong)(gong)(gong)(gong)件(jian)所受切削(xue)力、夾緊力大，發熱(re)量多，以及加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)表(biao)面有較顯(xian)著的(de)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)硬化現象(xiang)，工(gong)(gong)(gong)(gong)(gong)件(jian)內部存在著較大的(de)內應力，如果粗、粗加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)連續進行(xing)(xing)，則精(jing)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)后的(de)零件(jian)精(jing)度會因為應力的(de)重新分布而很快(kuai)喪失。對于某些加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)精(jing)度要求高的(de)零件(jian)。在粗加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)之(zhi)后和精(jing)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)之(zhi)前，還應安排低(di)溫退火或時效處理工(gong)(gong)(gong)(gong)(gong)序來消除內應力。
