Shot peening operation is used to improve the mechanical properties of the materials. In this study new rotary peening machine is fabricated. The Hardness and Compressive stress were investigated with help of Vickers Hardness and UTM respectively. The peening parameters such as number of balls (75,100,125), diameter of ball (8,10,12mm), speed (200,300,400rpm) is considered and experimental setup is formulated by L9 orthogonal array. The above parameters are optimized by Taguchi method and MINITAB software. The microstructures of the sample are viewed with help of SEM images. |
