In this wave of change, the mechanical automation technology is constantly innovating, integrating advanced technologies such as cloud computing, Internet of Things, big data, etc., and realizing a qualitative leap. These innovations have been widely used in a number of fields, providing solid support and strong impetus for the transformation and upgrading of the manufacturing industry and intelligent development. With the continuous progress of technology, intelligent manufacturing will lead the manufacturing industry towards a more efficient, intelligent and sustainable future.

I. Application of CNC Machine Tools
As the core equipment in modern mechanical manufacturing, the importance of CNC machine tools is self-evident. It can accurately, efficiently and automatically complete a variety of complex machining tasks through pre-set programs. Compared with traditional machine tools, the application of CNC machine tools significantly improves the production speed and product quality, greatly reduces the production time and defective rate, thus effectively reducing production costs. High flexibility and adaptability of CNC machine tools is another highlight. In today's rapidly changing market demand, CNC machine tools can be customized according to the customer's needs, quickly adjust the production plan, easy to cope with small batches, multiple varieties of production tasks. This ability not only meets the diversified needs of the market, but also enhances the market competitiveness of enterprises. In addition, CNC machine tools also have high-precision machining capabilities, which can ensure the dimensional accuracy and surface quality of products. This is important for improving the overall performance and extending the service life of products. At the same time, the automated operation of CNC machine tools also reduces the labor intensity of workers and improves work efficiency and safety.

II. Introduction of Virtualized Production Technology
Virtualized production technology is a major innovation in the field of intelligent manufacturing. It utilizes advanced computer simulation technology to mimic the actual production process, thereby identifying and solving potential problems at the product design stage. This technology not only shortens the product launch cycle and reduces R&D costs, but also ensures product reliability and stability. Virtualized production technology realizes the whole process simulation from product design to manufacturing. This simulation not only includes the performance analysis of the product itself, but also covers all aspects of the production process, such as process flow, equipment layout and logistics path. In this way, enterprises can conduct comprehensive evaluation and optimization of product design, process and production process without actual production. In addition, virtualized production technology introduces a networked operating function, enabling operators to adjust and optimize the computer's deduction process in a networked state. This ability to interact in real time not only improves the accuracy and reliability of the simulation, but also enables companies to respond faster to market changes and adjust production plans.

III. Application of IoT Technology and Sensors
The application of IoT technology and sensors constitutes a solid cornerstone of intelligent monitoring and control and plays a crucial role in the development of smart manufacturing. IoT technology, as a core component of smart manufacturing, realizes the free flow and efficient sharing of data between equipment by seamlessly connecting physical equipment, precision sensors and advanced computer systems. This technology enables intelligent scheduling and optimization of equipment resources based on real-time production needs, ensuring a smoother production process and a significant increase in productivity. Sensors, as the right hand of IoT technology, are found in every corner of the machinery manufacturing. They can real-time and accurately capture all kinds of key data in the production process, such as temperature, pressure, vibration and other core parameters. These data provide a solid support for the intelligent monitoring and control of the production process.

IV. Integration of Industrial Internet Technology
The integration of industrial Internet technology also promotes the intelligent development of smart manufacturing. Through the introduction of cloud computing, big data and other technologies, enterprises can build an intelligent supply chain management system to achieve intelligent scheduling and optimization of the supply chain. This intelligent supply chain management not only improves the operational efficiency and market competitiveness of enterprises, but also provides consumers with a more personalized and efficient service experience. Mechanical automation technology innovation in the context of intelligent manufacturing is leading the transformation and upgrading of the manufacturing industry and high-quality development. With the continuous progress of technology and the continuous expansion of application scenarios, mechanical automation technology will play a more important role in intelligent manufacturing, injecting a strong impetus for the sustainable development of the manufacturing industry.
