Against the backdrop of the manufacturing industry’s shift towards intelligence, the deep integration of the lean production model’s principle of “eliminating waste and continuous improvement” with Smart Manufacturing technologies has become a key path to enhancing production efficiency and core competitiveness. Based on the core ideas of lean production, this paper constructs a Smart Manufacturing system encompassing labor optimization, Smart Manufacturing, AI-based inspection, unmanned delivery, virtual factories, and big data decision-making. It clarifies the overall framework of “5 subsystems and 88 tools”, with a focus on two main dimensions: the design logic of the Smart Manufacturing system and the implementation path of core intelligent technologies. By integrating key technologies such as equipment IoT, photographic inspection, and unmanned delivery, it achieves rule coverage and intelligent decision-making throughout the entire production process, providing theoretical support and practical reference for building an efficient, flexible, and low-cost Smart Manufacturing system for manufacturing enterprises.
