This paper describes a computer-aided die design system of progressive die for making CPT grid. An approach to the development of the automatic design system is based on knowledge-based rules. The developed system is designed by considering several factors, such as grid geometry and punch profile. Grid, a key component of electronic gun, is formed through a sequence of many operations, among which the pilot piercing, beading, notching, bending, swaging and slotting etc. Using the developed system, design parameters are determined and output is generated in graphic forms. Therefore the developed system provides part drawing and the assembly drawing of die set.
