Experimental Investigation for Damping Vibration using Secondary Bed Material

Abstract

Unwanted vibration in machine tools like milling, lathe, grinding machine is one of the main problem as it affects the quality of the machined parts, tool life and noise during machining operation. Hence these unwanted vibrations are needed to be suppressed or damped out while machining. Therefore the present work concentrates and aims on study of different controllable parameter that affect the responses like vibration amplitude and roughness of machined part. The part to be machined is kept on sandwich of plates made up of polymer and composite material. The sandwich along with the part to be machined is fixed on the slotted table of horizontal milling machine. Finite element analysis (FEA) was carried out to know the resonance frequencies at which the structure should not be excited.
