The Influence of EDM Parameters in Finishing Stage on Material Removal Rate

In this work, the influence of different EDM parameters (current, pulse on-time, pulse off-time, arc voltage) in finishing stage on the material removal rate as a result of application copper electrode to a workpiece (cold work steel DIN1.2379) has been investigated. Design of the experiments was chosen full factorial and statistical analysis was usedfor analysis of experimental data in this study. Finally, to select the optimal machining conditions presented a mathematical model to achieve suitable material removal rate.
