Experimental Analysis of the Critical Voltage of an Electrochemical Discharge Machining Process

Electrochemical discharge machining is a recent technique in the field of non-traditional machining. This process is capable of machining insulators like glass and ceramics. Recently many researches are being carried out on this technique to obtain an optimal machining condition. However, many aspects of this technology demand an extensive research and development in this field. However, now many aspects of this machining technology still demand further extensive in-depth research and development. In this paper, the process of electrochemical discharge machining is carried out by varying the various process parameters such as tool diameter, electrolyte type and electrolytic concentration. The spark generation voltage in each of these cases is compared. The effect of insulated tool material on the spark generation voltage is also discussed.
