3、ols. 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(tái)電子計(jì)算機(jī)，這表明人類(lèi)創(chuàng)造了可增強(qiáng)和部分代替腦力勞動(dòng)的工具。它與人類(lèi)在農(nóng)業(yè)、工業(yè)社會(huì)中創(chuàng)造的那些只是增強(qiáng)體力勞動(dòng)的工具相比，起了質(zhì)的飛躍，為人類(lèi)進(jìn)入信息社會(huì)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

4、，在美國(guó)誕生了第一臺(tái)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(lái)，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（19521970年）early computers computational speed low and the prevailing scientific computing and data processing is not affected, but can not meet the requirements of real-time control mach

5、ine. 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

6、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(duì)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(tái)機(jī)床專(zhuān)用計(jì)算機(jī)作為數(shù)控系統(tǒng)，被稱(chēng)為硬件連接數(shù)控（hard-wired nc），簡(jiǎn)稱(chēng)為數(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

7、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 univer

8、sal 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 pr

9、ocessing 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(guò)來(lái)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(guó)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(chēng)之為微處理器（microprocessor），又可稱(chēng)為中央處理單元（簡(jiǎn)稱(chēng)cpu）。1974 microprocessor to be used in cnc system. this is because the function of the computer is

10、 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 en

11、ough, 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(tái)機(jī)床能力有富裕（故當(dāng)時(shí)曾用于控制多臺(tái)機(jī)床，稱(chēng)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(guò)多處理器結(jié)構(gòu)來(lái)解決。由于微處理器是通用計(jì)算機(jī)的核心部件，故

12、仍稱(chēng)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 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(guó)內(nèi)習(xí)慣稱(chēng)微機(jī)）的性能已發(fā)展到很高的階段，可以滿(mǎn)足作為數(shù)控系統(tǒng)核心部件的要求。數(shù)控

13、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 1970s 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1

14、990年的第六代-基于pc（國(guó)外稱(chēng)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 theday-to-day nc, in essence, is that computer numerically controlled.還要指出的是，雖然國(guó)外早已改稱(chēng)為計(jì)算機(jī)數(shù)控（即cnc）了，而我國(guó)仍習(xí)慣稱(chēng)數(shù)控（nc）。所以我們?nèi)?/p>

23、udes computer power.從微觀(guān)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(lái)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 parts2.1.1 可以加工出傳統(tǒng)機(jī)床加工不出來(lái)的曲線(xiàn)、曲面等復(fù)雜的零件。because computers are superb computing power can be accurately calculated instantaneous each coordi

24、nate 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(dòng)的運(yùn)動(dòng)量，因此可以復(fù)合成復(fù)雜的曲線(xiàn)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

25、實(shí)現(xiàn)加工的自動(dòng)化，而且是柔性自動(dòng)化，從而效率可比傳統(tǒng)機(jī)床提高37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 an

26、other 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(chǔ)能力，可以將輸入的程序記住和存儲(chǔ)下來(lái)，然后按程序規(guī)定的順序自動(dòng)去執(zhí)行，從而實(shí)現(xiàn)自動(dòng)化。數(shù)控機(jī)床只要更換一個(gè)程序，就可實(shí)現(xiàn)另一工件加工的自動(dòng)化，從而使單件和小批生產(chǎn)得以自動(dòng)化，故被稱(chēng)為實(shí)現(xiàn)了柔性自動(dòng)化。2.1.3 high precision machining parts, the si

27、ze 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

28、other self-regulatory functions, thus achieving long unattended processing.2.1.5 擁有自動(dòng)報(bào)警、自動(dòng)監(jiān)控、自動(dòng)補(bǔ)償?shù)榷喾N自律功能，因而可實(shí)現(xiàn)長(zhǎng)時(shí)間無(wú)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 machi

29、ne , 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(dòng)強(qiáng)度，節(jié)省了勞動(dòng)力（一個(gè)人可以看管多臺(tái)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(duì)市場(chǎng)需求作出快速反應(yīng)等等。these advantages are our predecessors did not expect, is a very major breakthrou

30、gh. 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

31、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(dòng)化的核心技術(shù)和基礎(chǔ)技術(shù)。 2.2, the macro view of the necessity 2.2、宏觀(guān)看改造的必要性from a macro perspective, the military industrial developed countries, the machinery industry, in the late 1970s, ea

32、rly 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

33、, 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, incl

34、uding 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 mu

35、ch stronger. and we in the information technology to transformtraditional 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

36、 year a large number of imports of mechanical and electrical products. this also explains the macro cnc transformation of the need.從宏觀(guān)上看，工業(yè)發(fā)達(dá)國(guó)家的軍、民機(jī)械工業(yè)，在70年代末、80年代初已開(kāi)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(duì)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(guò)程中采用數(shù)控機(jī)床、fmc、fms外，還包括在產(chǎn)品開(kāi)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

37、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(duì)國(guó)外軍、民機(jī)械工業(yè)進(jìn)行深入改造（稱(chēng)之為信息化），最終使得他們的產(chǎn)品在國(guó)際軍品和民品的市場(chǎng)上競(jìng)爭(zhēng)力大為增強(qiáng)。而我們?cè)谛畔⒓夹g(shù)改造傳統(tǒng)產(chǎn)業(yè)方面比發(fā)達(dá)國(guó)家約落后20年。如我國(guó)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(guān)上說(shuō)明了機(jī)床數(shù)控化改造的必要性。third, cnc machine tools and production lines of the transformation of the market 三、機(jī)床與生產(chǎn)線(xiàn)數(shù)控化改造的市場(chǎng)3.1, c

38、nc transformation of the market 3.1、機(jī)床數(shù)控化改造的市場(chǎng)my current machine total more than 380 million units, of which only the total number of cnc machine tool 113,400 taiwan, or that chinas cnc rate of less than 3 percent. over the past 10 years, chinas annual output of about 0.6 cnc machine tools to 0.8 mi

39、llion units, an annual output value of about 1.8 billion yuan. cnc machine tools annual rate of 6 per cent. chinas 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

40、 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

41、 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 companys products, markets, efficien

42、cy and impact the survival and development of enterprises. therefore, we must vigorously raise the rate of cnc machine tools. 我國(guó)目前機(jī)床總量380余萬(wàn)臺(tái)，而其中數(shù)控機(jī)床總數(shù)只有11.34萬(wàn)臺(tái)，即我國(guó)機(jī)床數(shù)控化率不到3。近10年來(lái)，我國(guó)數(shù)控機(jī)床年產(chǎn)量約為0.60.8萬(wàn)臺(tái)，年產(chǎn)值約為18億元。機(jī)床的年產(chǎn)量數(shù)控化率為6。我國(guó)機(jī)床役齡10年以上的占60以上；10年以下的機(jī)床中，自動(dòng)/半自動(dòng)機(jī)床不到20，fmc/fms等自動(dòng)化生產(chǎn)線(xiàn)更屈指可數(shù)（美國(guó)和日本自動(dòng)和半自動(dòng)機(jī)床占60以

43、上）?？梢?jiàn)我們的大多數(shù)制造行業(yè)和企業(yè)的生產(chǎn)、加工裝備絕大數(shù)是傳統(tǒng)的機(jī)床，而且半數(shù)以上是役齡在10年以上的舊機(jī)床。用這種裝備加工出來(lái)的產(chǎn)品普遍存在質(zhì)量差、品種少、檔次低、成本高、供貨期長(zhǎng)，從而在國(guó)際、國(guó)內(nèi)市場(chǎng)上缺乏競(jìng)爭(zhēng)力，直接影響一個(gè)企業(yè)的產(chǎn)品、市場(chǎng)、效益，影響企業(yè)的生存和發(fā)展。所以必須大力提高機(jī)床的數(shù)控化率。3.2, import equipment and production lines of the transformation of nc market 3.2、進(jìn)口設(shè)備和生產(chǎn)線(xiàn)的數(shù)控化改造市場(chǎng)since chinas reform and opening up, many foreig

44、n enterprises from the introduction of technology, equipment and production lines for technological transformation. according to incomplete statistics, from 1979 to 1988 10, the introduction of technological transformation projects are 18,446, about 16.58 billion us dollars. 我國(guó)自改革開(kāi)放以來(lái)，很多企業(yè)從國(guó)外引進(jìn)技術(shù)、設(shè)備
