Abstract
This work presents the machining performance of cylindrical electrochemical magnetic abrasive machining for high efficiency machining of cylindrical surfaces. Experiments were conducted on self-developed process setup for machining of AISI-304 stainless steel workpiece based on central composite rotatable design technique of response surface methodology. The effect of different process variables (viz. workpiece rotational speed, current to electromagnet, electrolytic current and frequency of vibration) on output responses (viz. material removal [MR], surface roughness [Ra]) is investigated. Analysis of the model shows that the workpiece rotational speed and electrolytic current have a significant influence on MR and Ra. Increasing both the workpiece rotational speed and electrolytic current leads to significant increase in MR and simultaneous reduction in Ra due to synergistic effect of abrasion-assisted passivation and passivation-assisted abrasion.
