J.R. Thomas and A.G. Cohn, An Expert System for Hollow Extrusion Die Design (October 1, 1989).

Abstract

This report is based upon a project to develop a prototype expert system to design hollow extrusion dies. Input to the system consisted of a cross sectional representation of the required extruded shape. Previous reserach has concentrated on critiquing existing designs for possible areas of manufacturing difficulty but until now no one has attempted to automate the design process itself. Problems in building such a system are centred on representing and performing the required spatial reasoning, and inproducing a design which meet various conflicting design goals. Output from the prototype system consists of one or more designs which satisfied the constraints for the extrusion die. Further system development is required in order to identify the optimal design when more than one design is produced and to increasing the efficiency of the implementation.
