Surface roughness prediction and parametric optimization of shot blasting of Al7068 using RSM

The mechanical based shot blasting was used to remove the oxides and scales from the surface of the materials. It was used to enhance the surface properties. In this work, aluminium 7068 alloy was involved in the shot blasting process. The particle velocity, standoff distance (SOD) and impact angles...

Summary:The mechanical based shot blasting was used to remove the oxides and scales from the surface of the materials. It was used to enhance the surface properties. In this work, aluminium 7068 alloy was involved in the shot blasting process. The particle velocity, standoff distance (SOD) and impact angles were included as input factors. These factors were mainly affects the Surface Roughness (SR). The round steel balls with diameter with 2 mm diameter were used for the shot blasting process. In addition to that, the elliptic and square shape of glass beads particles were used to enhance the surface finish. The parametric effect and surface roughness optimization was achieved through Response Surface Methodology (RSM). The role of factors has been analyzed through the variance test.
