VIBRATION MINIMIZATION USING ELECTRORHEOLOGICAL DAMPER DURING HARD TURNING

Hard turning has gained substantial response in metal machining since it has substituted the cycle of traditional process i.e. turning, heat treatment and finish grinding associated with hard parts. This current research goals at evolving an electrorheological fluid damper for reducing vibrations of tools and endorsing improved machining results during hard turning. The ER fluid performs like a spring having nonlinear vibration features tackled by configuration of ER fluid, the electric parameters of electric field and the shape of plunger. Turning investigations are conducted to attain a set of electrical compositional and shape constraints which will reduce tool vibrations and endorse improved cutting performance throughout turning of steel EN24 of 49 HRC with minimum fluid application. It is perceived that utilization of ER fluid damper decreases tool vibrations and increases turning performance efficiently. If this awareness gets commercialize it will beneficial for machining industries.
