Micro-electro discharge machining of nonconductive zirconia ceramic: investigation of MRR and recast layer hardness

Increasing material removal rate (MRR) and minimizing recast layer hardness are critical issues in machining non-conductive ceramic using micro-electro discharge machining(micro-EDM). This paper presents the analysis of MRR and recast layer hardness of zirconium oxide (ZrO2) due to micro-EDM usi...
