【文章內(nèi)容簡(jiǎn)介】 s, RISC chip, as well as multiCPU control system with highresolution detector of the absolute exchange digital servo system, taken at the same time improve the machine dynamic and static characteristics of effective measures, the highspeed highprecision machine has been efficient greatly enhanced. (2) Flexible includes two aspects: CNC system itself flexibility, NC system is modular in design, functional coverage, can be cut and strong, and easy to meet the needs of different users。 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。s various intelligent behaviors. To the development 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 network 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 p
