Abstract
The need for zirconia material is increasing nowadays due to excellent properties such as high strength, wear resistance, hot hardness, and chemical stability. Zirconia material is used in dental frameworks such as crowns, refractory material, lab crucible, wear coating, and electroceramics. In the present research study, machining characteristics for drilling the zirconia are studied using developed electrochemical discharge machining (ECDM) setup, which is a hybridization process (ECDM) of electrochemical machining (ECM) and electro-discharge machining (EDM). The effect of input parameter voltage is studied on the surface integrity of the machined surface using one factor at a time (OFAT). From the results, it is evident that at higher levels of voltage, the material removal rate and overcut increase. Moreover, high thermal energy results into the crack propagation in the material due to brittle nature of zirconia which ultimately leads to its fracture.
