Domestic CAM systems integrated with AI technology have made significant progress in the generation and application evaluation of intelligent CNC programming strategies. Machine learning and knowledge graphs assist in strategy generation, including process parameter optimization. System development requires designing architectures and building knowledge bases. Comparative analysis is used to verify its efficiency and quality. Although facing constraints such as standards and talent, they have brought about changes in intelligent manufacturing. In the future, cooperation between industry, academia, and research, as well as talent cultivation, should be strengthened.
