(54) Method and apparatus for forming parts from a continuous stock material and associated forge


(57) The present invention provides a method for forming a plurality of parts, such as spade-type boring bits (410), from a continuous stock material (12). Thus, the various steps of the forming method of the present invention can be performed to predetermined portions of the continuous stock material (12) prior to separating the continuous stock material into discrete parts, thereby enhancing the efficiency of the forming process. In the forging method, the forge can incrementally rotate the ram (61,102) after one or more parts have been forged. By repeating the incremental rotation of the ram (61,102), the forge will eventually rotate the ram a full 360°.
