Abstract: This paper presents the study of hybrid machining process consisting of electrochemical dissolution and magnetic abrasive machining. Experiments were conducted on self-developed cylindrical electrochemical magnetic abrasive machining (C-EMAM) setup to explore the finishing results of the process on non-magnetic stainless steel using unbonded magnetic abrasives. The effect of electrolytic current, magnetic flux density and rotational speed of workpiece on material removal and surface roughness were investigated. It was observed that the rotational speed of the workpiece, magnetic flux density and electrolytic current should be properly fitted to achieve passivation-abrasion synergism. The problems associated with the process, which reduces the performance are also discussed.
