Effect of Particle Concentration and Sliding Velocity in Magnetic Abrasive Finishing of Brass Pipe
The present study investigates the influence of magnetic field on the internal surface finish of Brass UNS C26800 pipe. The input parameters such as sliding velocity of electromagnets, concentration ratio (castor oil and magnetic abrasive particles) and number of cycles were varied in the selected range and their effect was comprehended in terms of percentage change in surface finish (%?Ra). The remaining process parameters were kept constant throughout the experimentation. According to the results, % ?Ra initially increases and afterwards decreases with an increase in sliding velocity of electromagnets in case of concentration ratio 7:3 and 8:2. But, in case of concentration ratio 9:1, there is uniform increase in %?Ra with an increase in sliding velocity. Also, at low sliding velocities (0.62 mm/sec and 1.23 mm/sec), the %?Ra decreases with an increase in concentration ratio but at 2.46 mm/sec, the %?Ra increases with increase in amount of oil added.
