【正文】 rd technology of numerical control of our country and some views equipped of developing from two aspects of strategy and tactics. The engineering level of equipment industry and modernized intensity are determining the level of the whole national economy and modernized intensity , numerical control technology and equip , develop new developing new hightech industry and most advanced industry To can make technology and basic equipment most (national defense industry industries , such as information technology and their industry , biotechnology , industry , aviation , spaceflight ,etc. ). Marx has ever said the differences of different economic times, do not lie in what is produced , lie in how produce , with what means of labor produce . Manufacturing technology and equipping the most basic means of production that are that the mankind produced the activity, and numerical control technology to equip most central technology. Nowadays the manufacturing industry all around the world adopts the technology of numerical control extensively, in order to improve manufacturing capacity and level, improve the adaptive capacity and petitive power to the changeable market of the trends . In addition every industrially developed country in the world also classifies the technology and numerical control equipment of numerical control as the strategic materials of the country, not merely take the great measure to develop one39。 (4)Servo drive technology。 In the fields of aviation and aerospace industry, its processing39。 Simplification programming, simplification operation aspect intellectualization, like intellectualized automatic programming, intellectualized manmachine contact surface and so on。s OSEC (Open System Environment for Controller), China39。 German Simens (Siemens) the pany displays Open Manufacturing Environment (opening manufacture environment, is called OME) and so on, had reflected the numerical control engine bed processing the tendency which develops to the work direction takes the new technical standard, the standard establishment about numerical control system design development gauge As noted previously, there are better monability , flexibility , adaptability , expanding in the open numerical control system, countries such as . , European Community and Japan ,etc. implement the strategic development plan one after another , carry on research and formulation of the systematic norm of structural numerical control of the open system (OMAC , OSACA , OSEC ), 3 of world heavy economy carry on the same science plan and standardize formulation nearly in a short time most, have indicated a new arrival of period of change of the technology of numerical control. Our country started research and formulation which standardized the frame of ONC numerical control system of China too in 2020. About the numerical control standard The numerical control standard is a kind of trend of informationbased development of manufacturing industry. Numerical control technology information exchange of 50 year born , to based on ISO6983 standard, adopt G , M code describes how processes, its essential characteristic faces the processing course, obviously, he can39。 Appearance quality is relatively poor。 Numerical control technological application expand efforts to be better。 Set up intact related system , plete training , service work ,etc. of high quality support the system. . The bad mechanism causes the brain drain , restraining technology and technological route from innovating again , products innovation, and has restricted the effective implementation of planning , has often planned the ideal , implement the difficulty. . Enterprises are indifferent in autonomous innovation in technology, key technology is engineered and indifferent. Lathe standard lag behind, level relatively low, numerical control system new standard study enoughly. 3 strategic thinking until technology and industrialization of numerical control of our country develop Strategic consideration Our country of strategic consideration makes the big country , should try hard to accept the front instead of the back transformation in the world industry shifts , should master and make key technology advancedly , otherwise in a new round of international industrial structure adjustment, of our country manufacturing industry step forward the empty core . We regard resource , environment , market as cost, possibility got to exchange assemble the centre , but not master the status of the manufacturing center of key technology , will so influence the development process of the modern manufacturing industry of our country seriously. We should stand in the height of national security strategy paying attention to the technology of numerical control and industry39。 Will not have cheap and products rich in the petitiveness without scale 。在集成化基礎(chǔ)上，數(shù)控系統(tǒng)實(shí)現(xiàn)了超薄型、超小型化；在智能化基礎(chǔ)上，綜合了計(jì)算機(jī)、多 媒體、模糊控制、神經(jīng)網(wǎng)絡(luò)等多學(xué)科技術(shù)，數(shù)控系統(tǒng)實(shí)現(xiàn)了高速、高精、高效控制，加工過程中可以自動修正、調(diào)節(jié)與補(bǔ)償各項(xiàng)參數(shù)，實(shí)現(xiàn)了在線診斷和智能化故障處理；在網(wǎng)絡(luò)化基礎(chǔ)上， CAD/CAM與數(shù)控系統(tǒng)集成為一體，機(jī)床聯(lián)網(wǎng)，實(shí)現(xiàn)了中央集中控制的群控加工。在復(fù)雜環(huán)境以及多變條件下，加工過程中的刀具組合、工件材料、主軸轉(zhuǎn)速、進(jìn)給速率、刀具軌跡、切削深度、步長、加工余量等加工參數(shù)，無法在現(xiàn)場環(huán)境下根據(jù)外部干擾和隨機(jī)因素實(shí)時動態(tài)調(diào)整，更無法通過反饋控制環(huán)節(jié)隨機(jī)修正CAD/CAM中的設(shè)定量，因而影響 CNC的工作效率和產(chǎn)品加工質(zhì)量。 (2)柔性化 包含兩方面：數(shù)控系統(tǒng)本身的柔性，數(shù)控系統(tǒng)采用模塊化設(shè)計(jì)，功能覆蓋面大，可裁剪性強(qiáng)，便于滿足不同用戶的需求；群控系統(tǒng)的柔性，同一群控系統(tǒng)能依據(jù)不同生產(chǎn)流程的要求，使物料流和信息流自動進(jìn)行動態(tài)調(diào)整，從而最大限度地發(fā)揮群控系統(tǒng)的效能。 (4)實(shí)時智能化 早期的實(shí)時系統(tǒng)通常針對相對簡單的理想環(huán)境，其作用是如何調(diào)度任務(wù)，以確保任務(wù)在規(guī)定期限內(nèi)完成。例如在數(shù)控系統(tǒng)中配備編程專家系統(tǒng)、故障診斷專家系統(tǒng)、參數(shù)自動設(shè)定和刀具自動管理及補(bǔ)償?shù)茸赃m應(yīng)調(diào)節(jié)系統(tǒng)，在高速加工時的綜合運(yùn)動控制中引入提前預(yù)測和預(yù)算功能、動態(tài)前饋功能，在壓力、溫度、位置、速度控制等方面采用模糊控制，使數(shù)控系統(tǒng)的控制性能大大提高，從而達(dá)到最佳控制的目的。圖形用戶界面極大地方便了非專業(yè)用戶的使用，人們可以通過窗口和菜單進(jìn)行操作，便于藍(lán)圖編程和快速編程、三維彩色立體動態(tài)圖形顯示、圖形模擬、圖形動態(tài)跟蹤和仿真、不同方向的視圖和局部顯示比例縮放功能的實(shí)現(xiàn)。 (3)插補(bǔ)和補(bǔ)償方式多樣化 多種插補(bǔ)方式如直線插補(bǔ)、圓弧插補(bǔ)、圓柱插補(bǔ)、空間橢圓曲面插補(bǔ)、螺紋插補(bǔ)、極坐標(biāo)插補(bǔ)、 2D+2螺旋插補(bǔ)、 NANO插補(bǔ)、 NURBS插補(bǔ) (非均勻有理 B樣條插補(bǔ) )、樣條插補(bǔ) (A、 B、C樣條 )、多項(xiàng)式插補(bǔ)等。 (5)多媒體技術(shù)應(yīng)用 多媒體技術(shù)集計(jì)算機(jī)、聲像和通信技術(shù)于一體，使計(jì)算機(jī)具有綜合處理聲音、文字、圖像和視頻信息的能力。平板顯示器具有科技含量高、重
