Investigation of surface roughness in micro-EDM of nonconductive ZrO2 ceramic with powder mixed dielectric fluid

This paper investigates the average surface roughness (Ra) in micro-electrical discharge machining of electrically nonconductive zirconium oxide (ZrO2) ceramic using powder mixed dielectric. The gap voltage and concentration of tantalum carbide (TaC) powder are considered as the variable paramete...
