Damping Analysis of Composites Used in Drilling Machine Bed

Abstract

Vibrations are generally occurs during the machining process as drilling, milling etc. which is the main cause of defects in the machine tools. So vibrational damping study is very necessary for minimizing the vibrational effect on the machines bed. At present work glass fiber epoxy and glass fiber polyester are the composites used as the drilling machine bed as a base of the work piece. The purpose of the paper is to analyze the damping of sandwich composites used in this work is calculating by the energy balance approach method
