Abstract: The proposal of "Made in China 2025" marks my country's gradual transformation and upgrading to Industry 4.0, and that intelligent manufacturing has become a new direction for future development. The mechanical automation of mechanical manufacturing is the basis for the realization of intelligent manufacturing. The rapid development of current mechanical manufacturing technology and artificial intelligence manufacturing and the increasing degree of mechanical automation in mechanical manufacturing have been widely used. Studies have shown that the application of mechanical automation in mechanical manufacturing can effectively improve enterprise production efficiency, reduce human resource costs, improve enterprise operating efficiency, and make great contributions to social and economic development.
