【正文】 ntrol 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(shì) 1 國(guó)內(nèi)外數(shù)控系統(tǒng)發(fā)展概況 隨著計(jì)算機(jī)技術(shù)的高速發(fā)展，傳統(tǒng)的制造業(yè)開(kāi)始了根本性變革，各工業(yè)發(fā)達(dá)國(guó)家投入巨資，對(duì)現(xiàn)代制造技術(shù)進(jìn)行研究開(kāi)發(fā)，提出了全新的制造模式。 group control system flexibility, with a control system pursuant to the requirements of different production processes, materials flow and information flow automatically dynamically adjusted to maximize their group control system performance. (3) Process of posite and multiaxis to reduce the process time for the main purpose of supporting the posite processing, and are moving towards multiaxis, multifunction control of the direction of series development. NC Machine Tool Technology posite refers to the workpiece in a single machine on a fixture, through an automatic tool change, rotating spindle head or turntable, and other measures to acplish multiple processes, multisurface machining pound. Axis CNC technology, Siemens 880axis control system for up to 24 axes. (4) Realtime Intelligent early for the realtime system is usually relatively simple ideal environment, and its role is to scheduling tasks, to ensure that the task be pleted within a specified time limit. And artificial intelligence is used to model the realization of mankind39。在復(fù)雜環(huán)境以及多變條件下，加工過(guò)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(zhǎng)、加工余量等加工參數(shù)，無(wú)法在現(xiàn)場(chǎng)環(huán)境下根據(jù)外部干擾和隨機(jī)因素實(shí)時(shí)動(dòng)態(tài)調(diào)整，更無(wú)法通過(guò)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。 (4)實(shí)時(shí)智能化 早期的實(shí)時(shí)系統(tǒng)通常針對(duì)相對(duì)簡(jiǎn)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。圖形用戶(hù)界面極大地方便了非專(zhuān)業(yè)用戶(hù)的使用，人們可以通過(guò)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(dòng)態(tài)圖形顯示、圖形模擬、圖形動(dòng)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)。 (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。根據(jù)不同 的功能需求，將基本模塊，如 CPU、存儲(chǔ)器、位置伺服、 PLC、輸入輸出接口、通訊等模塊，作成標(biāo)準(zhǔn)的系列化產(chǎn)品，通過(guò)積木方式進(jìn)行功能裁剪和模塊數(shù)量的增減，構(gòu)成不同檔次的數(shù)控系統(tǒng)
