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 CAD / CAM, such as automatic programming design parameters automatically set, tool pensation 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 pensation 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 (nonuniform rational Bspline interpolation), spline interpolation (A, B, C kind), such as polynomial interpolation. A variety of functions such as pensation gap pensation vertical pensation quadrant error pensation, and measurement systems pitch error pensation, and speedrelated feedforward pensation and temperature pensation, with nearly smooth and exit, as well as the opposite point of the cutter radius pensation. (4) highperformance PLC contents contents performance CNC system PLC control module can be directly used ladder diagram or highlevel 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 technologyputers, audiovisual and munication technology, and it has the puter integrated voice, text, images and video information. In NC technology, multimedia technology can be applied to information processing integrated, intelligent, realtime monitoring system in the field and production equipment fault diagnosis, monitoring of process parameters such as production has a significant value. Development of the Architecture (1) integration of a highly integrated CPU, programmable RISC chips and largescale 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. 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.
