2、代，鋼鐵、機(jī)械、化工等重工業(yè)正逐漸向發(fā)展中國家轉(zhuǎn)移。我國目前經(jīng)濟(jì)發(fā)展已經(jīng)過了發(fā)展初期，正處于重化工業(yè)發(fā)展中期?！ ∥磥?0年將是中國機(jī)械行業(yè)發(fā)展最佳時(shí)期。美國、德國的重化工業(yè)發(fā)展期延續(xù)了18年以上，美國、德國、國四國重化工業(yè)發(fā)展期平均延續(xù)了12年，我們估計(jì)中國的重化工業(yè)發(fā)展期將至少延續(xù)10年，直到2015年。因此，在未來10年中，隨著中國重化工業(yè)進(jìn)程的推進(jìn)，中國企業(yè)規(guī)模、產(chǎn)品技術(shù)、質(zhì)量等都將得到大幅提升，國產(chǎn)機(jī)械產(chǎn)品國際競爭力增強(qiáng)，逐步替代進(jìn)口，并加速出口。目前，機(jī)械行業(yè)中部分子行業(yè)如船舶、鐵路、集裝箱及集裝箱起重機(jī)制造等已經(jīng)受益于國際間的產(chǎn)業(yè)轉(zhuǎn)
3、移，并將持續(xù)受益；電站設(shè)備、工程機(jī)械、床等將受益于產(chǎn)業(yè)轉(zhuǎn)移，加快出口進(jìn)程關(guān)鍵詞:數(shù)控工業(yè)化發(fā)展數(shù)控加工工藝目錄第一章數(shù)控機(jī)床的產(chǎn)生第1數(shù)控系統(tǒng)的發(fā)展········································1第二章數(shù)控機(jī)床的發(fā)展2.1數(shù)控系統(tǒng)的展··········································22.2機(jī)床的發(fā)展趨勢·········································2第三章數(shù)控機(jī)床的分類3.1按加工工藝方法分類·························
