Abstract: This paper describes the phases involved in developing several PC-based computer aids for sheet-metal work. A blank layout program was first developed, followed by flat patterning and design considerations of progressive dies. An attempt is made to link the programs together to form a useful package for the design of progressive dies. The program incorporates a number of expert design rules and provides an automated solution for progressive-die layout with the following features: automated blank layout, punch-shape determination and optimisation to take advantage of standard commercial punches; automated staging of the punches considering punch interference and minimum die-opening separation; die plate configuration, etc. This software provides a good aid to progressive die design and, since it is PC-based, it is within the reach of many small tool and die shops. © 1989.
