A female die of a closed die set and a punch for near net warm forging complex shaped parts such as lugs from axi-symmetrical workpieces are disclosed. The punch includes a bottom forming surface having opposed chamfer surfaces which move workpiece material laterally in the cavity, prior to and during warm forging, such that the die cavity is substantially evenly filled. Consequently, the resulting parts are evenly filled without requiring that the workpieces fit snugly in the die cavity.
