A Progressive die is used to transform flat strips of sheet metal into a formed part. This transformation is performed progressively by a series of stations that cut and bend the material into a desired shape. The progressive dies reduce the time and cost of producing complex sheet metal components. The design and manufacture of these dies are difficult. CAD/CAM systems have been proved very useful tools for this task. In this paper, a new system for design of the piercing and bending progressive die is described. In this system, piercing and bending operation are separated and the sequencing of each type is done individually. In this system first sequence of the piercing stations are determined then bending operations are sequenced based on a classification and fuzzy algorithm. Also, neural network systems are used to determine final angle of bends and die parameters. The capability of the system is shown using a sheet metal component.
