Patents by Inventor Adam R. Groseclose

Adam R. Groseclose has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11651120
    Abstract: A system is provided for producing a die that forms a sheet metal blank into a workpiece for a stamped vehicle component. The system includes a processor receiving design data associated with the workpiece. The processor produces a computer simulation based on the data and determines a stretching index of the workpiece. The processor compares the stretching index to an index threshold. The processor generates a stretching failure signal when the stretching index is above the index threshold. The processor generates a stretching acceptance signal, and a display device indicates that the workpiece has a fracture when the stretching index is below the index threshold. The display device indicates that the workpiece does not have the fracture, when the display device receives the stretching acceptance signal, such that a die manufacturing device transforms a tool material into the die.

  • 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.
