Investigation and Analysis of Magneto Rheological Fluid Damper for Suppressing Tool Vibration during Hard Turning

Tool vibration is a frequent and major problem in the manufacturing industry where metal cutting operations take place. It mainly affects the surface finish of the work piece, tool life and produce irritating noise. In order to restrain tool vibration, it is necessary to develop and analyze suitable methods which increases stability and improves the cutting performance. The project aims at analyzing a MR Damper suitable for the operation. MR fluid is composed of oil and varying percentages of iron particles that have been coated with an anti-coagulant material. This new class of device known as Magneto Rheologycal (MR) dampers will match well with the requirements and constraints of applications, including the necessity of having very low power requirements. A simple MR damper model is created for the work. The influence of MR damper was checked by measuring various parameters such as tool vibration, cutting force, surface roughness and tool wear. Taguchi design of experiments was used for conducting the cutting experiment.
