Lateral extrusion of gear- like components with radial tooth profile, has been studied in this paper. To analyze the process, the two types of theoretical approaches, i.e. the upper bound technique and the slab method of analysis have been applied and extrusion load values have been estimated. The theoretical results of load values estimated from the above approaches have been compared with theoretical and experimental results that given by a reference. Good agreement has been found among the predicted load values and those obtained from the experimental results.
