Application of the CAD/CAM integrated system is an effective means to improve the information technology level of the super-hard cutting tool enterprises, and the foundation and core of system development are the data processing. The structure and function of the CAD/CAM integrated system of super-hard cutting tools were analyzed. The requirement on processing data of the system was put forward. Some data processing methods were discussed, which included the database structure design, the query of design parameters and the feature information model of super-hard cutting tools in the system. Finally, the realization means of data processing were given. In short, it reduced the complexity of the development process, effectively improved the running performance of the system.
