ips that can improve the CNC system integration and hardware and software operating speed. Application FPD flat panel display technology can improve display performance. Flatpanel displays with high science and technology content, light weight, small size, low power consumption and portability advantages can be realized Supersized, a counterweight to the emerging and CRT display technology, display technology in the 21st century the mainstream. Application of advanced packaging and interconnect technologies, semiconductors and surface mount technology integration. By increasing the density of integrated circuits, reducing the length and number of interconnection products to reduce prices, improve performance, reduce ponent size, improve the reliability of the system. (2) easy to implement modular hardware modular NC systems integration and standardization. According to various functional requirements, the basic modules, such as CPU, memory, position servo, PLC, the input and output interfaces, and munications modules, making the standard Series products, through functional buildingblock approach to cutting the number of steps and modules, a NC system at different grades. (3) machine interconnection work for remote control of unmanned operation. Machine through working, can be in any one machine on the other machine programming, configuration, operation, operating, different machine can be displayed on the screen each machine on the screen. (4) generalopen the closedloop control mode to adopt a mon puter ponent Bus, modular, open, embedded architecture, ease of cutting, expansion and upgrading, can be posed of different grades, different types, different degree of integration CNC system. Closedloop control mode is the traditional CNC system only for single closedopenloop control mode proposed. The manufacturing process is a multivariable control and the role of integrated processing plex process, including processing, such as size, shape, vibration, noise, temperature and thermal deformation, and other factors, therefore, to achieve the process of multiobjective optimization, Multivariable must adopt the closedloop control, realtime processing in the dynamic adjustment process variables. Processing the adoption of open universal realtime closedloop control mode the whole dynamic, easy realtime intelligent puter technology, work technology, multimedia technology, CAD / CAM, servo control, adaptive control, dynamic data management and dynamic tool pensation, dynamic simulation and other high technology into one, a tight closedloop manufacturing process control system to achieve integrated, intelligent, workbased. 中文翻譯 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。在現(xiàn)代制造系統(tǒng)中,數(shù)控技術(shù)是關(guān)鍵技術(shù),它集微電子、計算機(jī)、信息處理、自動檢測、自動控制等高新技術(shù)于一體,具有高精度、高效率、柔性自動化等特點,對制造業(yè)實現(xiàn)柔性自動化、集成化、智能化起著舉足輕重的作用。目前,數(shù)控技術(shù)正在發(fā)生根本性變革,由專用型封閉式開環(huán)控制模式向通用型開放式實時動態(tài)全閉環(huán)控制模式發(fā)展。在集成化基礎(chǔ)上,數(shù)控 系統(tǒng)實現(xiàn)了超薄型、超小型化;在智能化基礎(chǔ)上,綜合了計算機(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)與補償各項參數(shù),實現(xiàn)了在線診斷和智能化故障處理;在網(wǎng)絡(luò)化基礎(chǔ)上,
