Abstract: Method for punch forming center pilot opening or other wheel mounting surfaces in a pierceable metal performed wheel disc blank mounted internally of the wheel rim. A combination pierce and shave punch forms the disc opening in a single working stroke and produces a one-piece scrap slug containing both the pierced and shaved metal removed from the disc. The punch has a correlated dimensional relationship between disc material thickness, pierce punch diameter, shave punch diameter and shave punch set back from the pierce punch. A smoother, more cylindrical and more dimensionally consistent opening surface is obtained than with conventional pierce-only punches.
