A super finishing study was designed and conducted for bendingfatigue. AMS6265 parts were created: with and without superfinishing. Bending fatigue was tested using Single Tooth Fatigue(STF) and RR Moore rotating beam methods. The STF parts weredesigned with tooth geometry replicating a spiral bevel gearsection. Two lots of material were processed. Thus, a minimum oftwo carburized and hardened lots, two shot peen batches and twosuper finishing cycles (if applicable) were processed per samplegroup. A detailed metallurgical evaluation was performed tocharacterize the material and compare to actual spiral bevel gears.Analysis of the test data concluded no statistical difference inbending fatigue strength.
