The CNC equipment in the 21st century will be a certain intelligent system. The intelligent content includes all aspects of the CNC system: Dongguan CNC plant pursues the intelligence of machining efficiency and quality, such as adaptive control of machining process and automatic generation of process parameters; In order to improve the driving performance and the intelligence of convenient connection, such as feedforward control, adaptive calculation of motor parameters, automatic identification of load, automatic selection of model, self-tuning, etc; Simplify the programming, simplify the operation of intelligent, such as intelligent automatic programming, intelligent man-machine interface, etc; There are intelligent diagnosis, intelligent monitoring, convenient system diagnosis and maintenance, etc.
In order to solve the problems of traditional NC system closeness and industrial production of NC application software, Dongguan NC machining plant has developed a new NC system. At present, many countries research on Open CNC system, such as NGC (the next generation work station / machine control) of the United States, OSACA (open system architecture for control within Automation Systems) of European community, osec (open system environment for controller) of Japan, onc (open numerical control system) of China, etc. Open CNC system has become the future of CNC system. The so-called open CNC system means that the development of CNC system can be based on a unified operation platform, facing machine tool manufacturers and end users, through changing, adding or tailoring structural objects (CNC functions), forming a series, and can easily integrate users' special applications and technical know-how into the control system, so as to quickly realize different types of CNC system Different grades of open CNC system, the formation of brand-name products with distinct personality. At present, the architecture specification, communication specification, configuration specification, operation platform, function library and software development tools of open CNC system are the core of current research.
The networked CNC equipment of Dongguan CNC machining plant is a new highlight of the international famous machine tool Expo in recent two years. The networking of CNC equipment will greatly meet the needs of production lines, manufacturing systems and manufacturing enterprises for information integration, and it is also the basic unit to realize new manufacturing modes such as agile manufacturing, virtual enterprise and global manufacturing. Some famous CNC machine tool and CNC system manufacturing companies at home and abroad have launched relevant new concepts and prototypes in the past two years, such as "cyber production center" (CPC) exhibited by Mazak company of Japan in EMO2001; Okuma machine tool company of Japan displays "it Plaza" (it Plaza for short); The open manufacturing environment (OME) exhibited by Siemens in Germany reflects the development trend of CNC machine tools towards network.
