The whole frame of the system is designed, and the key techniques of the system modules are discussed in detail. The sizes and tolerance classes of blanking parts can be acquired by the system. Formability check for blanking parts can be acquired and a good blank layout scheme of blanking parts is defined by the system. The features of case are depicted by coding method and the most similar punching die case is confirmed by calculating similarity coefficient. The rewritten case, meeting similarity coefficient demands, can be stored and then the engi- neering drawing of punching die can be generated by the system.
