Abstract: Electrochemical Discharge Machining (ECDM) process has great potential to machine electrically non-conducting engineering ceramics and can be applied for micro-machining operation. This research paper includes the experimental investigation to study the range of the parametric setting for micro-machining operation as well as the effect of various process parameters such as applied voltage, electrolyte concentration and inter-electrode gap on Material Removal Rate (MRR), Radial Over-Cut (ROC) and Heat Affected Zone (HAZ) thickness during micro-drilling of non-conducting engineering ceramic materials such as Aluminium Oxide and Zirconium Oxide. The experiments have been performed using electrolyte of KOH and NaOH salt solution. In this paper, an experimental investigation has been made to find out the optimum value of ECDM process parametric conditions for higher MRR, lower overcut and also lower HAZ thickness during micro-drilling on ceramics. The quality of the hole during micro-drilling greatly depends on the applied voltage and electrolyte concentration.
