This paper describes the concept and basic features of shear forging. The basic idea of shear forging is the application of the flow model in metal cutting into cold forging to reduce the forging load dramatically. The feature of shear forging is to move a part of the workpiece freely by using the flow pattern of the continuous chip in metal cutting. The mechanics and the material movement in shear forging are similar to those in metal cutting, but the tribological issues in shear forging are very different from those in metal cutting since the forging velocity is extremely lower than the cutting velocity.
