Abstract: In at least one embodiment of the present invention, a method of forming a surface finished workpiece for a vehicle from a metal sheet is provided. The workpiece is machined, which generates string chips having a desired maximum length for removal from the workpiece. The method comprises stamping the metal sheet into a blank having an edge with a contour, wherein the edge includes a plurality of interrupting segments spaced apart. Stamping the blank into the workpiece. Machining at least a portion of the workpiece to within a surface tolerance, wherein the edge is a stamping precursor of the portion, whereby the generated string chips break at interrupting segments such that the lengths are less than the desired maximum.
