Electrochemical discharge machining (ECDM) has a great potential for machining of non-conductive materials like glass as compared with different existing non-conventional machining methods. The present research paper includes the experimental studies on Rotary Electrochemical Discharge Machining (RECDM) on soda-lime glass for analysis of the effect of machining parameters like applied voltage, electrolyte concentration, tool rotation, current ON-TIME, and duty ratio. Aqueous NaOH solution with varying concentration is used as an electrolyte and pulsed D.C. power supply is applied for small hole drilling operation of glass work-piece. A generalized equation for MRR has been derived using various statistical techniques and tried to find out the optimum values of process parameters by ROVOP method. The present work also include the Scanning Electron Microscope (SEM) study for topographical characteristics of machined surface of soda-lime glass machined by RECDM process that will provide further insight into the fundamental mechanism of this process.

Electrochemical discharge machining (ECDM) has a great potential for machining of non-conductive materials like glass as compared with different existing non-conventional machining methods. The present research paper includes the experimental studies on Rotary Electrochemical Discharge Machining (RECDM) on soda-lime glass for analysis of the effect of machining parameters like applied voltage, electrolyte concentration, tool rotation, current ON-TIME, and duty ratio. Aqueous NaOH solution with varying concentration is used as an electrolyte and pulsed D.C. power supply is applied for small hole drilling operation of glass work-piece. A generalized equation for MRR has been derived using various statistical techniques and tried to find out the optimum values of process parameters by ROVOP method. The present work also include the Scanning Electron Microscope (SEM) study for topographical characteristics of machined surface of soda-lime glass machined by RECDM process that will provide further insight into the fundamental mechanism of this process.
