The present work proposes a new non-conventional machining process. The proposed method is a combination of magneto-rheological finishing and rotational abrasive flow finishing process. The modeling of the new process was done on the brass workpiece at different magnetic field strengths and at different rotational speeds to observe its effect on final surface roughness and volumetric material removal. From the results, it was inferred that the value of surface roughness decreases with the increase in rotational speed and magnetic field for the constant number of cycles. This decrease in surface roughness value authenticates the active participation of the centrifugal force and rheological behavior of polishing fluid. The present study shows that with the rotation of magneto-rheological polishing fluid, an extra component of centrifugal force adds up to the resultant force which increases the volumetric removal rate and surface finish as compared to other finishing processes.
