Tool vibration is a frequent problem in the manufacturing industry where metal cutting operation takes place. It affects the surface finish of the work piece, tool life, and produce irritating noise. In order to restrain tool vibration in metal cutting, it is necessary to develop and analyze suitable methods which increases stability and also improves the cutting performance. Magnetorheological damper has received great attention due to their ability to reversibly change from a free flowing, linear, viscous liquid to a semi-solid when exposed to magnetic field in just few milliseconds and also found to be effective on suppressing tool vibration. The present investigation aims at studying the effect of magnetic field on the damping abilities of the magnetorheological (MR) damper during hard turning operation. MR damper was characterized and the effect of magnetic field on damping ability of MR damper and cutting performances like tool vibration, cutting force, cutting temperature, tool wear and surface roughness were analyzed. From the result, it was observed that direction of magnetic field parameter on magnetorheological damper reduces tool vibration effectively and brought forth better cutting performance.
