Document Summary
Forging in its simplest sense consists of heating and hitting. The metal is heated to a temperature where it is easy to deform, and then it is struck with a hammer to change the shape. The workpiece continues to be struck until it is deformed into the desired shape. The main variations have to do with the rate of deformation, process temperature, and tooling and workpiece nal geometry. The rate of deformation can go from fast in impact to slow in a squeezing operation. The process temperature can vary from a cold workpiece to a hot workpiece to hot workpiece and dies. The geometry varies from open die for simple and basic shapes, closed dies for a more de ned geometry to precision die to the absence of ash. Typically cut from a piece of bar of at stock which is cut to the desired length. Shapes that can be produced by forging are discrete parts.
