A Review on Vibration attenuation of Boring Bar by using Passive Dampers

The boring operation is a very critical manufacturing process which created surface roughness, tool wear, noise and vibration related problems. A deep internal boring operation in a workpiece is a classic example of chatter-prone machining. This review focuses on study of new damping composite materials for boring tool and introduces new advance viscoelastic materials for vibration attenuation purpose. This study also focuses Various damping techniques such as active damping and passive damping system and also an optimal selection of the parameters of a passive vibration dampers. This review introduces mechanics of boring process which affect tool wear, noise, surface roughness and hence influence on important factors such as productivity, production costs, etc. The main objective of the study is attenuation of vibration in boring bar by using passive dampers. This study will enhance the design of boring bar with ViscoElastic materials with reference to different machining parameters such as length to diameter ratio (L/D), Speed, feed, Depth of cut etc. The computed results on Experimental Modal Analysis, Machining Test and Surface Roughness will be compared to a conventional tool.
