Unwanted vibration in machine is one of the main problems as it affects the quality of the machined parts, tool life and noise during machining operation. 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 Secondary Bed Material (SBM). The parameters that can easily be controlled are feed, RPM of cutter, depth of cut, and number of plates that form the secondary bed material. Polymers like PVC, PP plates and...
