Review on Effect of Powder Mixed Dielectric on Material Removal Rate in Electric Discharge Machining
M. S. Bembde, J. K. Sawale
Abstract: Powder mixed electric discharge machining (PMEDM) is a recent innovation for enhancing the capabilities of electrical discharge machining process. The objective of present study is to realize the potential of silicon powder as additive in enhancing machining capabilities of PMEDM. Taguchi methodology has been adopted to plan and analyze the experimental results. L16 Orthogonal Array has been selected to conduct experiments. Peak current, Pulse on time, pulse off time, voltage, and concentration of fine silicon powder added into the dielectric fluid were chosen as input process variables to study performance in terms of material removal rate. The ANOVA analysis identifies the most important parameters to maximize material removal rate.
Keywords: Electrical discharge machining, Machining rate, Spark gap, Silicon powder concentration, Taguchi methodology
