Optimum blank design technology is required for near-net or net-shape cold forming using sheets. In this study, the backward tracing scheme of the finite element method is extended for the design of sheet blank in three-dimensional deformation. The backward tracing scheme has been developed for preform design in bulk forming, and applied to several forming processes successfully. A program for initial blank design in sheet forming which contains the capabilities of forward loading simulation by the finite element method and backward tracing simulation, has been developed and its effectiveness has been proved by applying to a square cup stamping process.
