Intelligent machine tools create conditions for production automation

CNC machine tools are the working machine in the equipment manufacturing industry. China is the world's largest machine tool consumer, but due to the large gap between China's CNC machine tools in design, materials, technology, parts processing, etc., the production capacity of domestic high-end CNC machine tools is still low, still A large number of high-end CNC machine tools need to be imported from abroad. In the future, the development trend of machine tools will gradually develop towards automation, intelligence and green.

Machine tools, as one of the most important equipments in the processing and manufacturing of industrial equipment, are constantly moving toward intelligence. CNC machine tools have pioneered the integration of precision manufacturing technology and related technologies, computer software and hardware technology, and compatible with network technology, and initiated the development of human intelligent production tools. When the CNC machine tool gradually has the logic judgment and teaching function through the numerical control device, this intelligent feature has begun to receive more attention.

Intelligent machine tools are machine tools that make judgments and decisions about the manufacturing process. Intelligent machine tools are able to monitor, diagnose and correct various types of deviations that occur during the production process after learning the entire manufacturing process. And can provide solutions for the optimization of production. In addition, the remaining life of the cutting tools, spindles, bearings and guides used can be calculated, allowing the user to know the remaining usage time and replacement time.

The emergence of intelligent machine tools has created conditions for the future equipment manufacturing industry to achieve full production automation. The intelligent machine tool can improve the machining accuracy and efficiency of the machine tool by automatically suppressing vibration, reducing thermal deformation, preventing interference, automatically adjusting the amount of lubricating oil, and reducing noise. For the further development of integrated manufacturing systems, the level of automation of a single machine tool can greatly reduce the workload of people in managing machine tools.

Intelligent machine tools enable people to have more energy and time to solve complex problems outside the machine tool, and to further develop intelligent machine tools and intelligent systems. The development and innovation of numerical control system has played an extremely important role in the intelligentization of machine tools. It can store a large amount of information, store, analyze, process, judge, adjust, optimize and control various information. Intelligent machine tools also have important functions such as: fixture database, dialog programming, tool path inspection, process time analysis, start time analysis, actual machining load monitoring, machining navigation, adjustment, optimization, and adaptive control. In other words, the machine tool evolved to send out information and think on its own, adapting itself to the requirements of a flexible and efficient production system.

The development of information technology and its integration with traditional machine tools have made the machine tools develop in the direction of digitalization, integration and intelligence. The application space of digital manufacturing equipment, digital production lines and digital factories will be more and more large; intelligent technology is used to realize the intelligent decision making, process adaptive control, error compensation intelligent control and complex surface processing motion trajectory under multi-information fusion. Features such as optimized control, fault self-diagnosis, intelligent maintenance, and information integration will greatly improve forming and machining accuracy and improve manufacturing efficiency. CNC machine tools need to strengthen the intelligent judgment of information.

The intelligent control of the machine tool puts forward higher requirements for the numerical control system. This requires the numerical control system not only to be open, inclusive and certain secondary development characteristics, but also to the CNC system interface according to the user's individualized requirements for its functions. Universality and forward-looking also raise high expectations.

With the rapid development of information technology and advanced manufacturing technology, the development depth and breadth of intelligent manufacturing equipment in China is increasing. The intelligent manufacturing equipment industry system represented by intelligent control systems, industrial robots, and automated complete production lines has taken initial shape. Major intelligent manufacturing equipment with independent intellectual property rights is achieving breakthroughs.
