Impact of Particle Damping Parameters on Surface Roughness of Bored Surface

Particle damping is a derivative of impact damping, which can be used to achieve structural damping. Real-time applications of particle damping are scarce in literature. For this study, a boring bar, filled with various metal particles, was used for internal turning operation, and the impacts on the surface roughness were studied. The influences of particle parameters on the surface roughness of machined surface are investigated in this study. In spite of the simplicity of the experiments conducted, the results provide us with a fundamental understanding of the parameters influencing particle damping.
