Passive damping is now the major means of suppressing unwanted vibrations. In the present work, attempt is made to predict and suppress the vibration level of cutting tool in CNC lathe, by using passive damping pad of Viscoelastic material S20. The effects of damping pad and cutting parameters on machine tool vibration were experimentally investigated. The experimentation is carried out on CNC lathe for dry turning of SS304 work piece material using single point carbide tool inserts of varying tool nose radius. Three levels for spindle speed, depth of cut, feed rate and tool nose radius were chosen as cutting variables. Design of Experiment (DOE) approach is selected for investigating the effect of varying controllable parameters on Tangential acceleration. The Taguchi method L27 orthogonal array was applied to design of experiment. This research work highlights the influence of cutting parameters on the tool vibration during machining using and optimizes the multi response parameters on turning operation using Taguchi Method and Regression Analysis.

Keywords: Transverse machine tool vibration; passive damping; ANOVA, Cutting Parameters, Taguchi Method.
