的程序流程,使加工程序簡練易懂,實現(xiàn)普通編程難以實現(xiàn)的功能。對于幾何形狀復(fù)雜的零件需借助計算機使用規(guī)定的數(shù)控語言編寫零件源程序,經(jīng)過處理后生成加工程序,稱為自動編程。人工完成零件加工的數(shù)控工藝分析零件圖紙制定工藝決策確定加工路線選擇工藝參數(shù)計算刀位軌跡坐標數(shù)據(jù)編寫數(shù)控加工程序單驗證程序主要用于點位加工(如鉆、鉸孔)或幾何形狀簡單(如平面、方形槽)零件的加工,計算量小,程序段數(shù)有限,編程直觀易于實現(xiàn)的情況等。這種方式比較簡單,很容易掌握,適應(yīng)性較大。常用方法手工編程是指編程的各個階段均由人工完成。第二章 數(shù)控加工的基本概念 基本概念數(shù)控編程是數(shù)控加工準備階段的主要內(nèi)容,通常包括分析零件圖樣,確定加工工藝過程;計算走刀軌跡,得出刀位數(shù)據(jù);編寫數(shù)控加工程序;制作控制介質(zhì);校對程序及首件試切。在高精尖裝備研發(fā)方面,要強調(diào)產(chǎn)、學(xué)、研以及最終用戶的緊密結(jié)合,以“做得出、用得上、賣得掉”為目標,按國家意志實施攻關(guān),以解決國家之急需。重點解決數(shù)控系統(tǒng)和相關(guān)功能部件(數(shù)字化伺服系統(tǒng)與電機、高速電主軸系統(tǒng)和新型裝備的附件等)的可靠性和生產(chǎn)規(guī)模問題。從我國基本國情的角度出發(fā),以國家的戰(zhàn)略需求和國民經(jīng)濟的市場需求為導(dǎo)向,以提高我國制造裝備業(yè)綜合競爭能力和產(chǎn)業(yè)化水平為目標,用系統(tǒng)的方法,選擇能夠主導(dǎo)21世紀初期我國制造裝備業(yè)發(fā)展升級的關(guān)鍵技術(shù)以及支持產(chǎn)業(yè)化發(fā)展的支撐技術(shù)、配套技術(shù)作為研究開發(fā)的內(nèi)容,實現(xiàn)制造裝備業(yè)的跨躍式發(fā)展。數(shù)控機床即使采用了數(shù)控技術(shù)的機床,或者說裝備了數(shù)控系統(tǒng)的機床。根據(jù)國家標準GB/T8129-1997,對機床數(shù)字控制的定義:用數(shù)字控制的裝置(簡稱數(shù)控裝置),在運行過程中,不斷地引入數(shù)字數(shù)據(jù),從而對某一生產(chǎn)過程實現(xiàn)自動控制,叫數(shù)字控制,簡稱數(shù)控。數(shù)控機床就是在這樣的背景下誕生與發(fā)展起來的。尤其是在造船、航天、航空、機床、重型機械以及國防工業(yè)更是如此。Automatic

technology, preempted future economic manding heights as technology development put forward higher request, especially the manufacturing technology more get the , we must promote machinery industry, has bee a pillar industry of the national determine machinery industry in the national economy, but also the important position to put forward higher requirement of mechanical : parts manufacturing technology。Science, technology and society, the vigorous development of mechanical processing product quality, variety and productivity put forward more and more high machining technology is to realize the modernization process automation products processing, one of the measures applied nc machining technology can improve the processing quality and productivity, solve several ordinary mechanical processing not settled by the processing technical problems, and greatly reduce processing cost, improve the overall economic benefit, but also can greatly improve labor conditions, enhances the quality of machine tool CNC based on digital form a realization of automatic processing control technologies, the door of digital and text coded instructions, recorded in control the way

生產(chǎn)率,解決若干普通機械加工所解決不了的的加工技術(shù)問題,大大降低加工成本,提高綜合經(jīng)濟效益,還能極大改善工人的勞動條件,提高工人的素質(zhì)。機械加工工藝是實現(xiàn)產(chǎn)品設(shè)計,保證產(chǎn)品質(zhì)量,節(jié)約能源,降低消耗的重要手段,是企業(yè)進行生產(chǎn)準備,計劃調(diào)度,加工操作,安全生產(chǎn),技術(shù)檢測和健全勞動組織的重要依據(jù),也是企業(yè)上品種、上質(zhì)量、上水平,加速產(chǎn)品更新,提高經(jīng)濟效益的技術(shù)保證。機械工業(yè)是國民經(jīng)濟各部門的裝備部,國民經(jīng)濟各部門的生產(chǎn)技術(shù)水平和經(jīng)濟效益,在很大程度上取決與機械工業(yè)所能提供裝備的技術(shù)性能、質(zhì)量和可靠性,因此,機械工業(yè)的技術(shù)水平和規(guī)模是衡量一個國家科技水平和經(jīng)濟實力的重要標志。所以,我們要振興機械工業(yè),使之成為國民經(jīng)濟的支柱產(chǎn)業(yè)。關(guān)鍵詞
