. Grinding of Superhard grinding tool has the properties of high efficiency, high precision and low cost. In this paper, grinding process of superhard grinding tools was analyzed, and the design method of PDA and the development of CAD/CAM integrated system were discussed. The key technologies of information database, eigen information extracting and output of process results are settled by establishing the superhard grinding tool integrated system, and organic combination between design and manufacture of tools and PDM system. The whole program and system are practicable and universal.
