One of the first forging processes for manufacturing near- or net-shape gears was the high energy rate forging process, which is a closed-die hot or cold forging process in which the work metal is deformed at unusually high velocities. Ideally, the final configuration of the forging is developed in one blow, or at most, a few blows.

Definition of forging Forging is defined as a metal working process that shape workpiece into desired dimensions by compressive forces applied through the use of dies and tools. Forging process is operated by hammering or pressing the metal. It is one of the oldest known metalworking processes with its origin about some thousands of years ago.
