Abstract:
1. A method to identify and classify deformations on a sheet metal panel, the method comprising: applying an abrasive screening material to the sheet metal panel's surface to identify deformations present on the sheet metal panel, the screening material being in the form of an object having dimensions substantially smaller than the dimensions of the sheet metal panel, wherein the application of the screening material includes swiping the screening material over the entire surface of the sheet metal panel, the screening material being abrasive in texture but sufficiently smooth to avoid scratching the sheet metal panel, thereby establishing screened deformations; rubbing an area around each identified deformations with a tool to determine the size of the identified deformations; and measuring the screened deformations employing a measuring rule to classify each identified deformation.
