Aerospace gear components are required to demonstrate excellent load carrying and endurance characteristics. Case hardened steels are often utilized for these parts, but often residual stresses are developed. These residual stresses are known to have a significant effect on distortion during the heat treatment and machining processes. This paper presents research conducted on gears manufactured from two different starting points: as-received bar material and hot-forged billet. This paper will also discuss the results of the work and compare the two sets of spur gears.
