However, Stressonic has a big difference in processing method compared to that of classical shot peening. Therefore, the peening management, which influences the peening effect, needs to be renewed. In this report, treatment conditions as amplitude, shot media (material, diameter), injecting distance, are set as Stressonic management items. Then the most suitable Stressonic condition is experimented by intensity and residual stress distribution obtained from the management above. Stressonic application is also studied using parts, such as gears and springs, and confirmed its quality after Stressonic process. As a result of study and experiment, Stressonic application has an outstanding peening effect.
