The automobile industry is an important pillar industry of our national economy. With the rapid development of the automobile industry, the efficient, high precision and high stability processing of the complex and key parts of the automobile has become an effective measure to shorten the production cycle of the products and improve the efficiency and competitiveness of the enterprises. At the same time, the virtual manufacturing technology, flexible manufacturing technology and integrated manufacturing technology in numerical control technology have been widely used in the modern automobile manufacturing industry. The intelligent development of NC manufacturing technology in the production process of automobile parts will become a development trend of the automobile manufacturing industry.



With the introduction of the 2025 core planning of industry 4 and China, it shows the arrival of the fourth industrial revolution in the world, and more emphasis is placed on the integration of information and industrialization in the manufacturing process, and the intelligentization of manufacturing equipment and its control, such as intelligent factory, intelligent production, human and machine interaction, Internet of things, machine self-organization, and number. Word - based manufacturing, etc. CNC machine tools and numerical control systems are the key elements to realize the intelligent production. The NC machining technology can realize the rapid prototyping of complex auto parts, and the virtual manufacturing technology, flexible manufacturing technology and integrated manufacturing technology in the numerical control technology have been widely used in the modern automobile manufacturing industry. The intelligent development of numerical control system in the manufacturing process of automobile parts will also become an inevitable trend of modern automobile manufacturing industry.

With the rapid development of the automobile industry, the efficient, high precision and high stability processing of the complex and key parts of the automobile has become an effective measure to shorten the production cycle, improve the efficiency and competitiveness of the enterprises. At the same time, the virtual manufacturing technology, flexible manufacturing technology and integrated manufacturing technology in numerical control technology have been widely used in the modern automobile manufacturing industry. As far as manual production is concerned, numerical control technology has laid a foundation for the standardization and standardization of auto parts manufacturing, and the improvement of the production quality and the actual equipment rate of domestic auto parts. Numerical control technology can provide a complete automatic solution for the manufacturing of key parts of the automobile. Based on the monitoring of the industrial Internet and the large data of the processing process, the processing data is received by the remote service. Then the virtual machining and program code detection are carried out. Then the processing state of the CNC system is self aware, self-learning, self-adaptive, and self-adaptive. The high quality machining of the workpiece is realized by the self optimization function, and then the application of the industrial robot and the on-line batch detection method of numerical control machine tools to realize the wide application of the CNC machine tool in the efficient flexible machining and batch manufacturing of the key parts of the automobile.

In the face of the high quality and high efficiency integrated intelligent manufacturing demand for multi degree of freedom parts and mould parts, the future CNC system is developing towards multi degree of freedom and compound processing. In addition, NC system needs more advanced trajectory planning strategy and motor control strategy to achieve high speed and high precision machining. With the development trend of intelligent manufacturing, the CNC system needs to have a highly intelligent man-machine interface, and realize the processing process planning function and the processing process diagnosis and adaptive control strategy. The future CNC system will realize the whole process of self monitoring and management of the machine tool itself.
