Metal Piercing - thelibraryofmanufacturing.com
Piercing is a metal forging technique that is often performed as an auxiliary process in conjunction with other forging processes, in the manufacture of a part. It can be used to create a cavity or hole in the work piece. Piercing does not break through the metal's surface, like a drilling operation.

Pierced forgings: tool development for a combined single step …
2010年12月5日 · As the geometry of the upper punch has no influence upon the surface of the piercing all of the four tested geometries could be used for forging. Future research projects should investigate, whether parts could be formed in one flashless precision forging process by combining multiple upper punches in one tool.
Blacksmiths use this process to reduce the thickness of bars by hammering the part on an anvil. Reducing the diameter of a bar by open-die forging; note the movements of the dies and the workpiece. The thickness of a ring being reduced by open-die forging. (a) through (c) Stages in impression-die forging of a solid round billet.
