This paper describes the structure and operation of a prototype intelligent system for progressive die design and manufacturing. The system is developed using X Window ‘C’ programs to create an interface linking the CAD (computer aided design) package, AutoCAD and the expert system shell, Kappa. AutoCAD is used for the input of the piece part geometry, creating the temporary drawings and final design drawings of the tool parts and assembly while Kappa is used to create the knowledge base, the databases of the standard tool parts and the menu system for entering design data. Purpose-built ‘C’ programs are also used for some numerically intensive computations, for example calculating the best material utilization. The system knowledge is based on a structured analysis of present press tool design techniques.
