The EMO2001 show , the New Japan Engineering Machine 5-face machining of composite spindle head can be realized four vertical plane of the processing and the processing of any angle, making 5-sided machining and 5-axis machining can be implemented on the same machine, but also can be realized inclined surface and inverted cone-hole processing。 German DMG's display DMUV oution series of machining centers can be under 5 in a clamping surface processing and 5-axis simultaneous machining , CNC system can be controlled or CAD / CAM, directly or indirectly controlled。
1。3 intelligent, open, network-based development of contemporary numerical control system the main trends
CNC equipment in the 21st century will be a certain intelligent systems , intelligent content included in the numerical control system in all areas: the pursuit of processing efficiency and processing quality of the intelligence, such as the adaptive control process , process parameters automatically generation ; To improve drive performance and the use of intelligent and convenient connections, such as feed forward control, the electrical parameters of the adaptive computing, automatic identification of the load is automatically selected model, self-tuning , etc。; to simplify programming and streamline operational aspects of intelligence, such as smart Auto-oriented programming , intelligent man-machine interface, etc。; there are intelligent diagnosis , intelligent control aspects, to facilitate the system diagnosis and maintenance。
To address the traditional closed and CNC numerical control system application software industrial production problems。 At present, many countries in open-architecture CNC system for research, such as the United States, NGC (The Next Generation Work-Station/Machine Control), the EC OSACA (Open System Architecture for Control within Automation Systems), Japan, OSEC (Open System Environment for Controller), China's ONC (Open Numerical Control System) and so on。 Open CNC system has become a numerical control system of the future path。 The so-called open-architecture CNC system is the development of numerical control system can be run in a unified platform for machine tool manufacturers and end users, by changing, adding or cutting the structure object (numerical control function), the formation of serialization, and can be easily user's for special applications and technical know-how into the control system, quick realization of different varieties and different grades of open CNC system, to form a distinctive brand personality 。 Currently open CNC system architecture specification , communication specifications, configuration specifications , operating platform , CNC system function library and function of numerical control system software development tools is the core of current research。
NC network equipment is well-known international machine tool fair the past two years a new bright spot。 NC network equipment will greatly satisfy the production lines, manufacturing systems, manufacturing information integration needs of enterprises , but also to achieve new manufacturing paradigms such as agile manufacturing, virtual enterprises , global manufacturing base unit。 Some well-known at home and abroad CNC machine tools and CNC manufacturing companies are launched in the last two years, the related new concepts and prototypes, such as EMO2001 exhibition, Japan Yamazaki Mazak( er, referred to as CPC); Japan OKUMA (Okuma) machine tool exhibition 'IT plaza' (Information Technology Square, referred to as IT Plaza ); Germany's Siemens (Siemens) the company exhibited Open Manufacturing Environment (open manufacturing environment, referred to as OME), etc。 , reflecting the NC machine to the network in the direction of the trend。
