Abstract
Forging dies are formed from a plurality of layers stacked together to form an assembly, or laminate. Each respective layer may be cut to form a portion of a die cavity, and the layers may be stacked together such that the cut portions are aligned to form the die cavity. The layers are fastened together to form a first die half and/or a second die half of disclosed forging dies. Each layer may be selectively removable from the die half for maintenance and/or replacement. Disclosed forging dies may be formed of lower grade materials as compared to conventional forging dies, and the number and thickness of layers may be varied to accommodate the specific part geometry of the part being forged. Related methods of making said forging dies and using said forging dies to make parts are also disclosed.
