In electric discharge drilling (EDD), rapid local heating and cooling of the workpiece surface by means of electric discharges results insurface layers (recast, heat affected and base material). In this study, the main ...

In electro discharge machining used frequently in tool production, copper and graphite is commonly used as electrode material. The reason of this is high melting temperatures and excellent electrical and thermal conductivity ...

The main objective of this study is to investigate the effect of Cu-Cr and Cu-Mo powder metal (PM) tool electrodes on electrical discharge machining (EDM) performance outputs. The EDM performance measures used in the study ...

In this study, heated silicon oil with added carbon and starch powders was used as dielectric liquid, instead of common hydro-carbon based dielectrics, to obtain better hole surface quality with rotating brass tube electrode ...
