(2) in heat treating, the same as tempering. operation, or a series of such operations, for reducing an ingotA casting intended for subsequent rolling, forging, or extrusion. or extruded shape to desired size before the finish(1) The forging operation in which the part is forged into its final shape in the finish die. If only one finish operation is scheduled to be performed in the finish die, this operation will be identified simply as finish; first, second, or third finish designations are so termed when one or more finish operations are to be performed in the same finish die.
