Abstract
Work piece and tool vibration control has been a subject of primary importance in manufacturing industry. High slenderness ratio is a reason for boring bar to be subjected to high amount of vibrations that accelerate the tool wear affecting the tool life, higher noise level and increased deviations. This review focuses on various damping techniques such as passive damping systems using particle impact damping and Magneto-Rheological (MR) fluid for vibration attenuation purpose. This also introduces the mechanics of boring operation that affects the tool wear, surface roughness, noise and hence affects the productivity. This review compares the results of boring bar using passive damping and the conventional tool on the basis of modal analysis of vibrating structure, and the test results. This paper explains the vibration behavior of a conventional boring bar and a boring bar using passive techniques for vibration reduction.
