Abstract:  
1. INTRODUCTION Shot peening is a process that improves the near-surface properties of metals by impacting the metal surface with small balls called shot that are made of metal or ceramic materials. The main effect is to improve the fatigue strength and it is used for various automotive parts. The dent is created at the surface due to impact by shot during the shot peening process. The surface roughness characteristics will be modified by the peening process. Changes to the surface are dependent on shot peening conditions and the mechanical properties of metal parts.
