which shows that human beings created to enhance and replace some of the mental work tools It and human agriculture industrial society in the creation of those who merely increase compared to manual tools from a qualitative leap for mankind s entry into the information society laid the foundation Six years later in 1952 computer technology applied to the machine in the United States was born first CNC machine tools Since then the traditional machine produced a qualitative change Nearly half a century since the CNC system has experienced two phases and six generations of development 1946 年誕生了世界上第一臺電子計(jì)算機(jī) 這表明人類創(chuàng)造了可增強(qiáng)和部分 代替腦力勞動的工具 它與人類在農(nóng)業(yè) 工業(yè)社會中創(chuàng)造的那些只是增強(qiáng)體力 勞動的工具相比 起了質(zhì)的飛躍 為人類進(jìn)入信息社會奠定了基礎(chǔ) 6 年后 即在 1952 年 計(jì)算機(jī)技術(shù)應(yīng)用到了機(jī)床上 在美國誕生了第一臺數(shù)控機(jī)床 從 此 傳統(tǒng)機(jī)床產(chǎn)生了質(zhì)的變化 近半個(gè)世紀(jì)以來 數(shù)控系統(tǒng)經(jīng)歷了兩個(gè)階段和 六代的發(fā)展 1 1 Numerical Control NC phase 1952 to 1970 1 1 數(shù)控 NC 階段 1952 1970 年 Early computer s computational speed low and the prevailing scientific computing and data processing is not affected but can not meet the requirements of real time control machine People have to use digital logic circuit tied into a single machine as a dedicated computer numerical control system known as the hardware connection NC HARD WIRED NC called the Numerical Control NC With the development of components of this phase after three generations that is in 1952 the first generation tube 1959 of the second generation transistor 1965 of the third generation small scale integrated circuits 早期計(jì)算機(jī)的運(yùn)算速度低 對當(dāng)時(shí)的科學(xué)計(jì)算和數(shù)據(jù)處理影響還不大 但 不能適應(yīng)機(jī)床實(shí)時(shí)控制的要求 人們不得不采用數(shù)字邏輯電路 搭 成一臺機(jī)床 專用計(jì)算機(jī)作為數(shù)控系統(tǒng) 被稱為硬件連接數(shù)控 HARD WIRED NC 簡稱為 外文資料翻譯 2 數(shù)控 NC 隨著元器件的發(fā)展 這個(gè)階段歷經(jīng)了三代 即 1952 年的第一代 電子管 1959 年的第二代 晶體管 1965 年的第三代 小規(guī)模集成電路 1 2 Computer Numerical Control CNC phase 1970 to present 1 2 計(jì)算機(jī)數(shù)控 CNC 階段 1970 年 現(xiàn)在 To 1970 GM has been a small computer and mass produced So it transplant system as the core component of NC have entered a Computer Numerical Control CNC stage in front of the computer should be universal word omitted To 1971 the United States INTEL company in the world will be the first time the two most core computer components computing and controller a large scale integrated circuit technology integration in a chip called the microprocessor MICROPROCESSOR also known as the central processing unit CPU 到 1970 年 通用小型計(jì)算機(jī)業(yè)已出現(xiàn)并成批生產(chǎn) 于是將它移植過來作為 數(shù)控系統(tǒng)的核心部件 從此進(jìn)入了計(jì)算機(jī)數(shù)控 CNC 階段 把計(jì)算機(jī)前面應(yīng) 有的 通用 兩個(gè)字省略了 到 1971 年 美國 INTEL 公司在世界上第一次將計(jì) 算機(jī)的兩個(gè)最核心的部件 運(yùn)算器和控制器 采用大規(guī)模集成電路技術(shù)集成在 一塊芯片上 稱之為微處理器 MICROPROCESSOR 又可稱為中央處理單元 簡稱 CPU 1974 microprocessor to be used in CNC system This is because the function of the computer is too small to control a machine tool capacity affluent the time has been used to control more than one machine called Group Control as a reasonable economic use of the microprocessor Minicomputer reliability and then not ideal Early microprocessor speed and functionality while still not high enough but can be adopted to solve the multi processor architecture As microprocessor core is a general computer components it is still known as the CNC 到 1974 年微處理器被應(yīng)用于數(shù)控系統(tǒng) 這是因?yàn)樾⌒陀?jì)算機(jī)功能太強(qiáng) 控 制一臺機(jī)床能力有富裕 故當(dāng)時(shí)曾用于控制多臺機(jī)床 稱之為群控 不如采用 微處理器經(jīng)濟(jì)合理 而且當(dāng)時(shí)的小型機(jī)可靠性也不理想 早期的微處理器速度 和功能雖還不夠高 但可以通過多處理器結(jié)構(gòu)來解決 由于微處理器是通用計(jì) 算機(jī)的核心部件 故仍稱為計(jì)算機(jī)數(shù)控 By 1990 PC machines personal computers domestic habits that computer performance has been developed to a high stage as a CNC system to meet the 外文資料翻譯 3 requirements of the core components NC system based on PC has now entered the stage 到了 1990 年 PC 機(jī) 個(gè)人計(jì)算機(jī) 國內(nèi)習(xí)慣稱微機(jī) 的性能已發(fā)展到很 高的階段 可以滿足作為數(shù)控系統(tǒng)核心部件的要求 數(shù)控系統(tǒng)從此進(jìn)入了基于 PC 的階段 In short CNC has also experienced a stage three generations That is in 1970 s fourth generation small computer 1974 of the fifth generation microprocessors and the sixth generation 1990 Based on the PC called PC BASED abroad 總之 計(jì)算機(jī)數(shù)控階段也經(jīng)歷了三代 即 1970 年的第四代 小型計(jì)算機(jī) 1974 年的第五代 微處理器和 1990 年的第六代 基于 PC 國外稱為 PC BASED Also pointed out that although the foreign computer has been renamed NC CNC but China still customary said Numerical Control NC Therefore we stress the day to day NC in essence is that computer numerically controlled 還要指出的是 雖然國外早已改稱為計(jì)算機(jī)數(shù)控 即 CNC 了 而我國仍 習(xí)慣稱數(shù)控 NC 所以我們?nèi)粘Ｖv的 數(shù)控 實(shí)質(zhì)上已是指 計(jì)算機(jī)數(shù)控 了 1 3 the trend of future development of NC 1 3 數(shù)控未來發(fā)展的趨勢 1 3 1 continue to open the sixth generation of PC based development 1 3 1 繼續(xù)向開放式 基于 PC 的第六代方向發(fā)展 Based on the PC with the open low cost high reliability rich in resources such as hardware and software features and more CNC system manufacturers will embark on this path At least it used PC as a front end machine to deal with the human machine interface programming networking and communications problems the former NC Some systems have the mandate PC machine with the friendly interface will be universal to all CNC system Remote communications remote diagnostics and maintenance will be more widespread 基于 PC 所具有的開放性 低成本 高可靠性 軟硬件資源豐富等特點(diǎn) 更多的數(shù)控系統(tǒng)生產(chǎn)廠家會走上這條道路 至少采用 PC 機(jī)作為它的前端機(jī) 來處理人機(jī)界面 編程 聯(lián)網(wǎng)通信等問題 由原有的系統(tǒng)承擔(dān)數(shù)控的任務(wù) PC 機(jī)所具有的友好的人機(jī)界面 將普及到所有的數(shù)控系統(tǒng) 遠(yuǎn)程通訊 遠(yuǎn)程診斷 外文資料翻譯 4 和維修將更加普遍 1 3 2 high speed and high precision Development 1 3 2 向高速化和高精度化發(fā)展 This is to adapt to high speed and high precision machine tools to the needs of the development direction 這是適應(yīng)機(jī)床向高速和高精度方向發(fā)展的需要 1 3 3 intelligent direction to the development 1 3 3 向智能化方向發(fā)展 With artificial intelligence in the computer field infiltration and the continuing development of the intelligent numerical control system will be continuously improved 隨著人工智能在計(jì)算機(jī)領(lǐng)域的不斷滲透和發(fā)展 數(shù)控系統(tǒng)的智能化程度將 不斷提高 1 adaptive control technology 1 應(yīng)用自適應(yīng)控制技術(shù) CNC system can detect some important information in the process and automatically adjust system parameters to improve the system running state purposes 數(shù)控系統(tǒng)能檢測過程中一些重要信息 并自動調(diào)整系統(tǒng)的有關(guān)參數(shù) 達(dá)到 改進(jìn)系統(tǒng)運(yùn)行狀態(tài)的目的 2 the introduction of expert guidance processing system 2 引入專家系統(tǒng)指導(dǎo)加工 the experience of skilled workers and experts processing and the general rules of law of special deposit system the process parameters to the database as the foundation and establish artificial intelligence expert system 將熟練工人和專家的經(jīng)驗(yàn) 加工的一般規(guī)律和特殊規(guī)律存入系統(tǒng)中 以工

機(jī)床數(shù)控化改造的必要性 2 1 microscopic view of the necessity of 2 1 微觀看改造的必要性 From the micro perspective CNC machine tools than traditional machines have the following prominent superiority and these advantages are from the NC system includes computer power 從微觀上看 數(shù)控機(jī)床比傳統(tǒng)機(jī)床有以下突出的優(yōu)越性 而且這些優(yōu)越性 均來自數(shù)控系統(tǒng)所包含的計(jì)算機(jī)的威力 2 1 1 can be processed by conventional machining is not the curve surface and other complex parts 2 1 1 可以加工出傳統(tǒng)機(jī)床加工不出來的曲線 曲面等復(fù)雜的零件 Because computers are superb computing power can be accurately calculated instantaneous each coordinate axis movement exercise should be instantaneous it can compound into complex curves and surfaces 由于計(jì)算機(jī)有高超的運(yùn)算能力 可以瞬時(shí)準(zhǔn)確地計(jì)算出每個(gè)坐標(biāo)軸瞬時(shí)應(yīng) 該運(yùn)動的運(yùn)動量 因此可以復(fù)合成復(fù)雜的曲線或曲面 2 1 2 automated processing can be achieved but also flexible automation to increase machine efficiency than traditional 3 to 7 times 2 1 2 可以實(shí)現(xiàn)加工的自動化 而且是柔性自動化 從而效率可比傳統(tǒng)機(jī)床 提高 3 7 倍 Because computers are memory and storage capacity can be imported and stored procedures remember down and then click procedural requirements to implement the order automatically to achieve automation CNC machine tool as a replacement procedures we can achieve another work piece machining automation so that single pieces and small batch production can be automated it has been called flexible automation 由于計(jì)算機(jī)有記憶和存儲能力 可以將輸入的程序記住和存儲下來 然后 按程序規(guī)定的順序自動去執(zhí)行 從而實(shí)現(xiàn)自動化 數(shù)控機(jī)床只要更換一個(gè)程序 外文資料翻譯 6 就可實(shí)現(xiàn)另一工件加工的自動化 從而使單件和小批生產(chǎn)得以自動化 故被稱 為實(shí)現(xiàn)了 柔性自動化 2 1 3 high precision machining parts the size dispersion of small easy to assemble no longer needed repair 2 1 3 加工零件的精度高 尺寸分散度小 使裝配容易 不再需要 修配 2 1 4 processes can be realized more focused in part to reduce the frequent removal machine 2 1 4 可實(shí)現(xiàn)多工序的集中 減少零件 在機(jī)床間的頻繁搬運(yùn) 2 1 5 have automatic alarm automatic control automatic compensation and other self regulatory functions thus achieving long unattended processing 2 1 5 擁有自動報(bào)警 自動監(jiān)控 自動補(bǔ)償?shù)榷喾N自律功能 因而可實(shí)現(xiàn)長 時(shí)間無人看管加工 2 1 6 derived from the benefits of more than five 2 1 6 由以上五條派生的好處 Such as reducing the labor intensity of the workers save the labor force one can look after more than one machine a decrease of tooling shorten Trial Production of a new product cycle and the production cycle the market demand for quick response and so on 如 降低了工人的勞動強(qiáng)度 節(jié)省了勞動力 一個(gè)人可以看管多臺機(jī)床 減少了工裝 縮短了新產(chǎn)品試制周期和生產(chǎn)周期 可對市場需求作出快速反應(yīng) 等等 These advantages are our predecessors did not expect is a very major breakthrough In addition CNC machine tools or the FMC Flexible Manufacturing Cell FMS flexible manufacturing system and CIMS Computer Integrated Manufacturing System and other enterprises the basis of information transformation NC manufacturing automation technology has become the core technology and basic technology 以上這些優(yōu)越性是前人想象不到的 是一個(gè)極為重大的突破 此外 機(jī)床 數(shù)控化還是推行 FMC 柔性制造單元 FMS 柔性制造系統(tǒng) 以及 CIMS 計(jì) 算機(jī)集成制造系統(tǒng) 等企業(yè)信息化改造的基礎(chǔ) 數(shù)控技術(shù)已經(jīng)成為制造業(yè)自動 化的核心技術(shù)和基礎(chǔ)技術(shù) 外文資料翻譯 7 2 2 the macro view of the necessity 2 2 宏觀看改造的必要性 From a macro perspective the military industrial developed countries the machinery industry in the late 1970s early 1980s has begun a large scale application of CNC machine tools Its essence is the use of information technology on the traditional industries including the military the Machinery Industry for technological transformation In addition to the manufacturing process used in CNC machine tools FMC FMS but also included in the product development in the implementation of CAD CAE CAM virtual manufacturing and production management in the implementation of the MIS Management Information System CIMS and so on And the products that they produce an increase in information technology including artificial intelligence and other content As the use of information technology to foreign forces the depth of Machinery Industry referred to as information technology and ultimately makes their products in the international military and civilian products on the market competitiveness of much stronger And we in the information technology to transform traditional industries than about 20 years behind developed countries Such as possession of machine tools in China the proportion of CNC machine tools CNC rate in 1995 to only 1 9 percent while Japan in 1994 reached 20 8 percent every year a large number of imports of mechanical and electrical products This also explains the macro CNC transformation of the need 從宏觀上看 工業(yè)發(fā)達(dá)國家的軍 民機(jī)械工業(yè) 在 70 年代末 80 年代初 已開始大規(guī)模應(yīng)用數(shù)控機(jī)床 其本質(zhì)是 采用信息技術(shù)對傳統(tǒng)產(chǎn)業(yè) 包括軍 民機(jī)械工業(yè) 進(jìn)行技術(shù)改造 除在制造過程中采用數(shù)控機(jī)床 FMC FMS 外 還包括在產(chǎn)品開發(fā)中推行 CAD CAE CAM 虛擬制造以及在生產(chǎn)管理中推 行 MIS 管理信息系統(tǒng) CIMS 等等 以及在其生產(chǎn)的產(chǎn)品中增加信息技術(shù) 包括人工智能等的含量 由于采用信息技術(shù)對國外軍 民機(jī)械工業(yè)進(jìn)行深入改 造 稱之為信息化 最終使得他們的產(chǎn)品在國際軍品和民品的市場上競爭力大 為增強(qiáng) 而我們在信息技術(shù)改造傳統(tǒng)產(chǎn)業(yè)方面比發(fā)達(dá)國家約落后 20 年 如我國 機(jī)床擁有量中 數(shù)控機(jī)床的比重 數(shù)控化率 到 1995 年只有 1 9 而日本在 1994 年已達(dá) 20 8 因此每年都有大量機(jī)電產(chǎn)品進(jìn)口 這也就從宏觀上說明了 機(jī)床數(shù)控化改造的必要性 外文資料翻譯 8 Third CNC machine tools and production lines of the transformation of the market 三 機(jī)床與生產(chǎn)線數(shù)控化改造的市場 3 1 CNC transformation of the market 3 1 機(jī)床數(shù)控化改造的市場 My current machine total more than 380 million units of which only the total number of CNC machine tool 113 400 Taiwan or that China s CNC rate of less than 3 percent Over the past 10 years China s annual output of about 0 6 CNC machine tools to 0 8 million units an annual output value of about 1 8 billion yuan CNC machine tools annual rate of 6 per cent China s machine tool easements over age 10 account for more than 60 below the 10 machines automatic semi automatic machine less than 20 per cent FMC FMS such as a handful more automated production line the United States and Japan automatic and semi automatic machine 60 percent above This shows that we the majority of manufacturing industries and enterprises of the production processing equipment is the great majority of traditional machine tools and more than half of military age is over 10 years old machine Processing equipment used by the prevalence of poor quality products less variety low grade high cost supply a long period in view of the international and domestic markets lack of competitiveness and a direct impact on a company s products markets efficiency and impact The survival and development of enterprises Therefore we must vigorously raise the rate of CNC machine tools 我國目前機(jī)床總量 380 余萬臺 而其中數(shù)控機(jī)床總數(shù)只有 11 34 萬臺 即 我國機(jī)床數(shù)控化率不到 3 近 10 年來 我國數(shù)控機(jī)床年產(chǎn)量約為 0 6 0 8 萬 臺 年產(chǎn)值約為 18 億元

percent of savings investment 同購置新機(jī)床相比 一般可以節(jié)省 60 80 的費(fèi)用 改造費(fèi)用低 特別 是大型 特殊機(jī)床尤其明顯 一般大型機(jī)床改造 只花新機(jī)床購置費(fèi)用的 1 3 交貨期短 但有些特殊情況 如高速主軸 托盤自動交換裝置的制作與安裝過 于費(fèi)工 費(fèi)錢 往往改造成本提高 2 3 倍 與購置新機(jī)床相比 只能節(jié)省投資 50 左右 4 3 2 stable and reliable mechanical properties structure limited 4 3 2 機(jī)械性能穩(wěn)定可靠 結(jié)構(gòu)受限 By the use of bed column and other basic items are heavy and solid casting components rather than kind of welding components of the machine after the high performance quality and can continue to use the new equipment for many years But by the mechanical structure of the original restrictions it is not appropriate to the transformation of a breakthrough 所利用的床身 立柱等基礎(chǔ)件都是重而堅(jiān)固的鑄造構(gòu)件 而不是那種焊接 構(gòu)件 改造后的機(jī)床性能高 質(zhì)量好 可以作為新設(shè)備繼續(xù)使用多年 但是受 到原來機(jī)械結(jié)構(gòu)的限制 不宜做突破性的改造 4 3 3 become familiar with the equipment ease of operation and maintenance 4 3 3 熟悉了解設(shè)備 便于操作維修 外文資料翻譯 13 The purchase of new equipment new equipment do not know whether to meet the processing requirements Transformation is not can be used to calculate the machine processing capacity In addition since the use of many years the operator of the machine has long been understood that in the operation use and maintenance of the training time is short quick Transformation of the machine tools installed we can achieve full
