A method of making a forging die for forging a part , the method comprising: forming a first die half , wherein forming the first die half comprises: cutting a first layer to form a first portion of a first die cavity ; cutting a second layer to form a second portion of the first die cavity ; stacking the first layer and the second layer together such that the first portion of the first die cavity and the second portion of the first die cavity are positioned with respect to one another to form the first die cavity and such that the first layer is stacked above the second layer and an upper surface of the first layer forms a first engagement surface ; and fastening the first layer and the second layer together to form the first die half ; and engaging the first die half with a second die half such that the first die cavity faces the second die half and the first engagement surface faces a second engagement surface of the second die half , wherein the first die cavity is configured to receive at least a portion of a preform , and wherein the forging die is configured to forge the part from the preform when the first die half and the second die half are pressed together, and wherein fastening the first layer and the second layer together to form the first die half comprises binding the first layer and the second layer together using a first plurality of fasteners that extend through at least a portion of each respective layer. forming a first die half , wherein forming the first die half comprises: cutting a first layer to form a first portion of a first die cavity ; cutting a second layer to form a second portion of the first die cavity ; stacking the first layer and the second layer together such that the first portion of the first die cavity and the second portion of the first die cavity are positioned with respect to one another to form the first die cavity and such that the first layer is stacked above the second layer and an upper surface of the first layer forms a first engagement surface ; and fastening the first layer and the second layer together to form the first die half ; and cutting a first layer to form a first portion of a first die cavity ; cutting a second layer to form a second portion of the first die cavity ; stacking the first layer and the second layer together such that the first portion of the first die cavity and the second portion of the first die cavity are positioned with respect to one another to form the first die cavity and such that the first layer is stacked above the second layer and an upper surface of the first layer forms a first engagement surface ; and fastening the first layer and the second layer together to form the first die half ; and engaging the first die half with a second die half such that the first die cavity faces the second die half and the first engagement surface faces a second engagement surface of the second die half , wherein the first die cavity is configured to receive at least a portion of a preform , and wherein the forging die is configured to forge the part from the preform when the first die half and the second die half are pressed together, and wherein fastening the first layer and the second layer together to form the first die half comprises binding the first layer and the second layer together using a first plurality of fasteners that extend through at least a portion of each respective layer. <EOS>
