SURFACE FINISH AUGMENTATION OF BORING OPERATION USING IMPACT DAMPERS

In the field of manufacturing industries, many new concepts and techniques have been introduced to improve its performance and adaptability to the international standards. In industries, boring operation suffer vibrations due to high over hang of the tool. In this study, improvement of the damping capability of boring tools is attempted using impact dampers. The technique is attempted to reduce the chatter in boring tool and thereby study improvement in surface finish. Slight structural alteration are done to the boring bar and then the effect of Impact Dampers, the overhang length of the boring tools and their cutting conditions on surface finish is studied. Theoretical and practical results are verified using regression analysis.
