Abstract : The purpose of the project was to evaluate the dynamic fatigue strength of spur gear teeth produced by advanced forging techniques in comparison to those manufactured by conventional forging methods. All of the advanced forging processes evaluated in this program used high-energy-rate forging techniques which produced gear blanks with integrally forged teeth. The die design and type of press were different for the three advanced processes; however, they produced similar as-forged gear blanks except for some variations in flash formation. On the basis of the results obtained, the best advanced forging process shows and advantage over the conventional forging process which is in the order of 5 to 8 percent.
