Abstract: In accordance with various embodiments, methods and systems are provided for designing a bead tool and a bead for sheet metal forming. In one embodiment, a method includes: storing, in a datastore, a library of bead tool data associated with a plurality of bead tools; receiving, by a processor, a plurality of parameters associated with at least one of a punch and a die of a desired bead tool; computing, by the processor, bead tool data for at least one of the punch and the die of the desired bead tool based on the plurality of parameters; providing, by the processor, a subset of bead tool data from the library of bead tool data; receiving, by the processor, a selection of bead tool data from the subset of bead tool data and the computed bead tool data; and generating, by the processor, bead geometry data based on the selection and the bead tool data associated with the selection.
