This paper describes an expert system of progressive die. Because of the complexity for die structure and of the critical problems for press machine mechanism in the progressive press process such as, the travel length in process, the equalized press load, and the other design parameter, it has been increased the requirement of the CAD system for progressive die design more an more. So, through this study, an expert system of progressive die has been developed. The results from the system developed were suggested the possibility of applications in the practice. To develop this system, it has used c-language under the HP-UNIX system and CIS customer language of the EXCESS CAD/CAM system. An application of this system will provide effective aids to the designer in this field.
