In this paper, a passive damping control system has been developed by computational investigation to decrease vibration in a machining process by inserting different shim materials beneath the insert. The different shim materials of carbide, aluminium, brass, and stainless steel are compared through computational analysis. In this computation analysis of different shim materials, the harmonic response and damping ratio are evaluated. The damping ratio is derived by half power bandwidth theory. This research work is led to conclude that harmonic response analysis and damping ratio accomplish that single point cutting tool with stainless steel shim is useful to reduce chatter.
