A tool and process utilizing the tool for forming a compressed-radius hem on a sheet metal assembly is disclosed. The tool 30, 40, 50, 60, 70, 88, 100 includes a concave portion formed by at least two surfaces 34, 36; 44, 46; 64, 66; 54, 55; 92, 93; 104, 106 that together define a cavity. A flange 26 on the perimeter of an outer panel 18 is initially formed to an approximate perpendicular angle and is then formed to about 45{. In a final forming step, an intermediate portion 74 of the flange 26 is engaged by the cavity and is formed into a compressed-radius hem. |
