Abstract
ABSTRACT Micro-Electric Discharge Machining (Micro-EDM) is an established machining process for making very small parts/components with accuracy and superior surface finish. The present work investigates the magnetic field-assisted Micro-EDM of inconel alloy with Tungsten electrode using Response Surface Methodology (RSM). The experiments were carried out based on the RSM design of experiments, especially facecentred cubic design with and without magnetic field assistance on Micro-EDM processes. The machining parameters for experimental design are voltage, capacitance and feed rate each varying at three levels. Material removal rate (MRR) is the response parameter. A mathematical model was developed for the prediction of MRR based on RSM methods. Analysis of variance was used to check the significance of model of MRR for both machining processes. The experimental observation shows that voltage, capacitance and its interactions are significant on the MRR. The MRR of magnetic field-assisted Micro-EDM is 22% more than that of non-magnetic field-assisted Micro-EDM.
