DEM based prediction of surface roughness in vibratory finishing

Abstract

In vibratory finishing, convex areas of workpieces tend to wear faster than concave areas. So we need to optimize polishing process time. In my research, I proposed a model of work surface and the way to predict surface roughness of polished work by polishing using discrete elemental method. I checked the simulation is valid compared with experiment result using a simple model. Finally, I measure preston coefficient which is important to predict surface roughness. This value is close to Literature data.
