  • Patent number: 10670515
    Abstract: A method and system for detecting edge cracks of an element of a sheet metal product is provided. The method includes calculating a first stress associated with a forming process employing a first die; calculating a second stress associated with a finishing process employing a second die; combining the first stress and the second stress to formulate a total stress; simulating the sheet metal product to produce a benchmark stress; and comparing the total stress and the benchmark stress to determine if the element predictively contains edge cracks.
    Type: Grant

  • Patent number: 10372849
    Abstract: Sheet metal is provided as a template to create a finished product. After various metal transformation techniques are performed on the sheet metal, the sheet metal may be converted to the finished product. The sheet metal manipulation may encompass different techniques, such as thinning, bending, cutting, and the like. The manipulated sheet metal may be sourced for various products, such as a body of a vehicle. The aspects disclosed herein combine various tests employed to detect the integrity of the sheet metal transformation into a singular output.
