Abstract: Unwanted vibration in machine tools like lathe, milling, grinding and other machine tools is one of the elementary problems as it affects the quality of the machined parts, tool life, and noise during machining operations. Particularly, in boring operation, the vibrations induced are the primary concern in the manufacturing industries. Hence, these unwanted vibrations are desired to be suppressed or damped out while machining. In present work, the damping ratios and natural frequencies of the boring bar vibrations have been estimated during boring operation with different composites such as Glass Fiber Reinforced Polyester (GFRP) and Glass Fiber Reinforced Epoxy (GFRE) on the tool post. It has been observed that GFRE composite gives good results compared to other composites. Further, the Fast Fourier Transform (FFT) technique has been utilized to find out the values of spectral power density and magnitude for various combinations of composites.
