Abstract
Closed die forging of spur gears is investigated using the slab method and the upper bound  technique. The tooth regions are approximated by prismatic rectangular sections. The  velocity field comprising three unit deformation regions is used. A constant frictional  stress between workpiece and forging die is assumed.  
The average punch pressure normalized by the flow stress of the gear material is  determined theoretically and compared with experimental results. The experimental work  is carried out on a commercial pure aluminum (Al 1100) at room temperature. The  forging process is carried out using one die geometry without using any additional blocker  (preform) dies.  
The theoretical predictions of forging pressures and deformation configurations agree  fairly well with the experimental results.
