Vibratory-based manufacturing processes such as polishing, and peening are widely used for surface enhancement applications. Vibratory peening is an excellent process to introduce residual stresses, improve fatigue life, and enhance the surface quality of metallic components. This research aims to understand the combined peeningpolishing mechanism in the vibratory peening process of a gas turbine engine's 3-stage blisk using a novel horizontal vibratory peening method. The research was aimed to understand the common understanding that the deeper the component in the vibratory machine, the higher would be the media-component interaction effect and better would be the peening effect. However, contrary to the hypothesis, the experimental findings showed significant peening (60.0 % higher than bottom) in the coupons near the top surface of the media in the trough.
