【正文】 根據不同 的功能需求，將基本模塊，如 CPU、存儲器、位置伺服、 PLC、輸入輸出接口、通訊等模塊，作成標準的系列化產品，通過積木方式進行功能裁剪和模塊數量的增減，構成不同檔次的數控系統。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行操作，便于藍圖編程和快速 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現。在復雜環(huán)境以及多變條件下，加工過程中的刀具組合、工件材料、主軸轉速、進給速率、刀具軌跡、切削深度、步長、加工余量等加工參數，無法在現場環(huán)境下根據外部干擾和隨機因素實時動態(tài)調整，更無法通過反饋控制環(huán)節(jié)隨機修正CAD/CAM中的設定量，因而影響 CNC的工作效率和產品加工質量。s various intelligent behaviors. To the developme nt of science and technology today, realtime systems and artificial intelligence bined with each other towards artificial intelligence is a realtime response, a more realistic field of development, and also in the realtime system with intelligent behavior, the more plex application development, resulting in the Intelligent realtime control of this new area. NC technology in the field, realtime intelligent control of the research and application of development along several main branches: adaptive control, fuzzy control, neural work control, experts control, learning control, feedforward control. For example, in CNC programming system with expert systems, fault diagnosis expert system parameters automatically set and tool management and automatic pensation, such as adaptive conditioning systems, in highspeed processing of the integrated motion control ahead of the introduction of budget projections and functional, dynamic Feedforward functions in pressure, temperature, position, velocity, control, fuzzy control, the control of the NC system performance greatly improved, so as to achieve optimal control purposes. functional development direction (1) The user interface is graphical user interface with the CNC system of dialogue between the user interface. Since different users interface requirements are different, thus the development of the workload of great user interface, user interface software developed into the most difficult part of. At present INTERNET, virtual reality, visualization in scientific puting and multimedia technologies, such as the user interface has put a higher demand. Graphical user interface greatly facilitates the use of nonprofessional users, it can be carried out through the window and menu operation, ease of programming and blueprint for rapid programming, threedimensional dynamic threedimensional color graphics, graphics, simulation, graphics, dynamic tracking and simulation, and the different directions view and partial display ratio scaling function can be achieved. (2) visualization in scientific puting visualization in scientific puting can be used for efficient data processing and interpretation of data, so that the exchange of information is no longer limited to using the written word and language, and can direct the use of graphics, image, animation, video and other information. Visualization technology and virtual environment technology, to further broaden the application areas, such as a drawing design, virtual prototyping technology, which shorten product design cycles, improving product quality, reduce production cost is of great significance. NC technology in the areas of visualization technology can be used for CA
