  • Patent number: 11373020
    Abstract: Systems and methods are provided for developing and producing a die using mesh data. A mesh data file representing a surface of the die is created. The mesh data file is configured in an original format that is one of a point-facet format or a node-element format. The mesh data file is translated into a translated format that is another of the point-facet format or the node-element format. Prior to building, the die, as represented by the mesh data file, is evaluated virtually.
    Type: Grant
    Filed: July 29, 2019
    Date of Patent: June 28, 2022
    Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLC
    Inventors: Ziqiang Sheng, Jounqmin Norman Goan, Adam R. Groseclose, Kleber Cabral

  • Patent number: 7130708
    Abstract: Sheet metal forming is a manufacturing process in which flat sheet metal is drawn into a die cavity to form a product shape. Draw-in amount is the single most important stamping index that controls all forming characteristics (strains and stresses), formability failures (splits, wrinkles) and surface quality (distortions) on a panel. Adaptation of a new die set for repetitively stamping sheet metal parts to a part design specification is simplified by using a math-based simulation of the stamping operation under specified engineering stamping conditions for the specified part. The stamping simulations are used to create an engineered draw-in map comparing selected locations on the peripheral edge of the stamped part with corresponding locations on the peripheral edge of its original sheet metal blank.
