2.2 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 computing and multimedia technologies, such as the user interface has put a higher demand. Graphical user interface greatly facilitates the use of non-professional users, it can be carried out through the window and menu operation, ease of programming and blueprint for rapid programming, three-dimensional dynamic three-dimensional 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 computing visualization in scientific

computing 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 CAD / CAM, such as automatic programming design parameters automatically set, tool compensation and tool management of dynamic data processing and display, as well as the processing of visual simulation, and other presentations.

(3) interpolation, and a variety of methods of compensation interpolation methods such as multiple linear interpolation, circular interpolation, cylindrical interpolation, space elliptical surface interpolation, thread interpolation, polar coordinates interpolation, 2 D +2 helical interpolation , NANO interpolation, interpolation NURBS (non-uniform rational B-spline interpolation), spline interpolation (A, B, C kind), such as polynomial interpolation. A variety of functions such as compensation gap compensation vertical compensation quadrant error compensation, and measurement systems pitch error compensation, and

speed-related feedforward compensation and temperature compensation, with nearly smooth and exit, as well as the opposite point of the cutter radius compensation.

(4) high-performance PLC contents contents performance CNC system PLC control module can be directly used ladder diagram or high-level language programming, with intuitive online debugging and online help function. Programming tools include the standard used lathe and milling machine PLC user program an example, users may PLC user program standards on the basis of editorial changes, thus easily build their own applications.

(5) application of multimedia technology of multimedia technology-computers, audio-visual and communication technology, and it has the computer integrated voice, text, images and video information. In NC technology, multimedia technology can be applied to information processing integrated, intelligent, real-time monitoring system in the field and production equipment fault diagnosis, monitoring of process parameters such as production has a significant value.

2.3 Development of the Architecture

(1) integration of a highly integrated CPU, programmable RISC chips and

large-scale integrated circuits FPGA, EPLD, CPLD and ASIC ASIC chips that can improve the CNC system integration and hardware and software operating speed. Application FPD flat panel display technology can improve display performance. Flat-panel 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 component 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 communications modules, making the standard Series products, through functional building-block approach to cutting the number of steps and modules, a NC system at different grades.

(3) machine interconnection network for remote control of unmanned operation. Machine through networking, 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.
