There are no products without high dependability of scale 。 CAD/CAM和 CNC之間沒有反饋控制環(huán)節(jié)，整個制造過程中 CNC只是一個封閉式的開環(huán)執(zhí)行機(jī)構(gòu)。數(shù)控技術(shù)軸，西門子 880系統(tǒng)控制軸數(shù)可達(dá) 24軸。當(dāng)前INTERNET、虛擬現(xiàn)實(shí)、科學(xué)計算可視化及多媒體等技術(shù)也對用戶界面提出了更高要求。編程工具中包含用于車床銑床的標(biāo)準(zhǔn) PLC用戶程序?qū)嵗脩艨稍跇?biāo)準(zhǔn) PLC用戶程序基礎(chǔ)上進(jìn)行編輯修改，從而方便地建立自己的應(yīng)用程序。在數(shù)控技術(shù)領(lǐng)域，應(yīng)用多媒體技術(shù)可以做到信息處理綜合化、智能化，在實(shí)時監(jiān)控系統(tǒng)和生產(chǎn)現(xiàn)場設(shè)備的故障診斷、生產(chǎn)過程參數(shù)監(jiān)測等方面有著重大的應(yīng)用價值。 (2)科學(xué)計算可視化 科學(xué)計算可視化可用于高效 處理數(shù)據(jù)和解釋數(shù)據(jù)，使信息交流不再局限于用文字和語言表達(dá)，而可以直接使用圖形、圖像、動畫等可視信息。而人工智能則試圖用計算模型實(shí)現(xiàn)人類的各種智能行為。由此可見，傳統(tǒng) CNC系統(tǒng)的這種固定程序控制模式和封閉式體系結(jié)構(gòu)，限制了 CNC向多變量智能化控制發(fā)展，已不適應(yīng)日益復(fù)雜的制造過程，因此，對數(shù)控技術(shù)實(shí)行變革勢在必行。 Certainly, it is difficult finally to have the day to hold up head that there is no Chinese numerical control equipment of scale . In equipping researching and developing highgrade , precision and advancedly , should emphasize the production, learning and research and close bination of end user, regard obtaining, using, selling as the goal, tackle key problems according to the national will, in order to solve the needing badly of the country. The technology of numerical control, emphasized innovation, put emphasis on researching and developing technology and products with independent intellectual property right before the petition, establish the foundation for the numerical control industry of our country , sustainable development of the equipment manufacture and even the whole manufacturing industry. 附錄 2 數(shù)控技術(shù)發(fā)展趨勢 1 國內(nèi)外數(shù)控系統(tǒng)發(fā)展概況 隨著計算機(jī)技術(shù)的高速發(fā)展，傳統(tǒng)的制造業(yè)開始了根本性變革，各工業(yè)發(fā)達(dá)國家投入巨資，對現(xiàn)代制造技術(shù)進(jìn)行研究開發(fā)，提出了全新的制造模式。 The research , formulation that relevant standards are normal lags behind. It is analyzed that the main reason for having disparity described above has the following several respect. the respect. Know to domestic numerical control industry process arduousness , plexity and longterm characteristic insufficiently。t meet demands of highspeed development of the technology of modern numerical control more and more already. For this reason, studying and making a kind of new CNC system standard ISO14649 (STEPNC ) in the world, its purpose is offering a kind of neutral mechanism not depending on the concrete system , can describe the unified data model in whole lifespan of the products , thus realize the whole manufacture process, and even the standardization of each industrial field product information. The appearance of STEPNC may be a revolution of the technical field of the numerical control, on development and even the whole manufacturing industry of the technology of numerical control , will exert a farreaching influence. First of all, STEPNC puts forward a kind of brandnew manufacture idea , in the traditional manufacture idea, NC processes the procedures to all concentrate on single puter. Under the new standard, NC procedure can be dispersed on Inter, this is exactly a direction of open , worked development of technology of numerical control. Secondly, STEPNC numerical control system also can reduce , process (about 75% ) drawing , process procedure work out (about 35% ) time and process (about 50% ) time greatly. At present, AmericanEuropean countries pay much attention to the research of STEPNC, Europe initiates IMS plan ( ) of STEPNC. 20 CAD/CAM/CAPP/CNC users , manufacturers and academic organizations from Europe and Japan participated in this plan. STEP Tools Company of . is a developer of the data interchange software of manufacturing industry in the global range, he has already developed and accused of the super model (Super Model ) of information exchange of machine tooling by counting, its goal is to describe all processing courses with the unified norm. Such new data interchange form has already been verified in allocating the SIEMENS , FIDIA and European OSACANC numerical control at present. 2 pairs of basic estimations of technology and industry development of numerical control of our country The technology of numerical control of our country started in 1958, the development course in the past 50 years can roughly be divided into 3 stages: The first stage is from 1958 to 1979, . closed developing stage. In this stages, technology of foreign countries blockade and basic restriction of terms of our country, the development of the technology of numerical control is paratively slow. During Sixth FiveYear Plan Period , the Seventh FiveYear Plan Period of the country in second stage and earlier stage in the Eighth FiveYear Plan Period , introduce technology , digest and assimilate, the stage of establishing the system of production domesticization arisesing tentatively. At this stage , because of reform and openingup and national attention , and study the improvement of the development environment and international environment, research , development and all making considerable progress in production domesticization of the products of the technology of numerical control of our country. The third stage is that on the later stage in the Eighth FiveYear Plan Period of the country and during the Ninth FiveYear Plan Period , implement the research of industrialization , enter market petition stage. At this stage, made substantive progress in industrialization of the domestic numerical control equipment of our country. In the Ninth FiveYear Plan latter stage, domestic numerical control domestic market share of lathe reach 50% , mix domestic numerical control system (pop
