【導(dǎo)讀】是嚴(yán)格按照從外部輸入的程序來自動(dòng)地對被加工零件進(jìn)行加工的。應(yīng)用計(jì)算機(jī)、自動(dòng)控制,自動(dòng)檢測及精密機(jī)械等高技術(shù)的產(chǎn)物。體現(xiàn)國家綜合實(shí)力的水平。它隨著信息技術(shù)、微電子技術(shù)、自動(dòng)化技術(shù)和檢測技。數(shù)控加工不僅要考慮夾具、刀具、主軸轉(zhuǎn)速、進(jìn)給量、背吃刀量等常規(guī)工藝的選擇。實(shí)踐中產(chǎn)生的問題。數(shù)控機(jī)床的廣泛使用給機(jī)械制造業(yè)生產(chǎn)方式、產(chǎn)業(yè)結(jié)構(gòu)、管。理方式帶來深刻的變化,它的關(guān)聯(lián)效益和輻射能力更是難以估計(jì)。加工機(jī)床及生產(chǎn)過程數(shù)控化,已經(jīng)成為當(dāng)今制造業(yè)的發(fā)展方向。數(shù)控加工的基本原理····························································1. 1.2機(jī)床的選用······································································1. 數(shù)控加工工藝的主要內(nèi)容···········································
