The automation of sheet metal machining can be reflected from many aspects. The automation of CNC punch is one of the sheet metal processing and production. The more common automatic processing equipment can effectively improve the efficiency of sheet metal production, and also can effectively ensure the mechanization and automation of sheet metal processing and production.

From the perspective of the main part of automation, the CNC punch is a key part in sheet metal processing, and also the core foundation of part processing. It uses a three box frame structure to ensure its stability, ensure the reliability of sheet metal processing components, and greatly reduce the errors caused in processing. After the numerical control punch is fixed, the traditional process technology can be improved through the application of automatic punch technology. With the replacement of automatic die, the construction efficiency is greatly improved. In specific application, the die information will be transferred to the control center of the sheet metal punching machine, and the processing can be automatically implemented. The application of system software in sheet metal machining automation is also very important, mainly because CNC software is used to control the implementation of punch technology.

The application of this software is relatively simple and accurate. This software is different from other software. During the comprehensive work, one software fails and other software can work normally [5]. In the application of special dies, different types and sizes of dies can be designed by combining different punch technology types and sizes. The overall working efficiency of sheet metal parts processing has been improved by automatic work.

The realization of the goal of automation of sheet metal processing machinery can effectively improve the overall quality level of processing. By strengthening the importance of ensuring the scientific application of technology from various aspects, it has a positive significance for the actual processing quality assurance. Through the research and analysis of sheet metal machining automation from various aspects, it is hoped that it can contribute to the actual development.
