Abstract
A workpiece applied for use with a cutting machine comprises a first outer surface, a second outer surface and a third outer surface. The third outer surface intersects the first outer surface and the second outer surface to define an extrusion-acting portion having an extruding portion. The workpiece can be used to form a cutter or a trimmed portion thereof. Accordingly, rapid production of cutters by molding machines can be realized, and blades of the molding machine for machining a produced cutter become readily replaceable. While a blade portion is machining, the extrusion-acting portion is applied to support and guide the workpiece, such that the surface machined by the blade portion can be extruded and polished simultaneously. Thus, machining qualities of the cutter, including finish, straightness and roundness, manufactured by applying the workpiece for the molding machine can be significantly improved.
