Abstract

Electro chemical discharge machining (ECDM) is a proven process for micro machining difficult to process non-conductive materials. The experimental results [material removal (MR) and tool wear (TW)], while fabricating shallow holes on soda lime glass using ECDM process; have been reported in the paper. The electrolytes viz. NaOH and NaNO3 were used during the micromachining on soda lime glass. The detailed parametric study was planned using the standard L9 orthogonal array. Influence of process parameters, namely electrolyte concentration, applied voltage, distance between electrodes and time of current flow on response parameter, i.e., MR were analysed. The results showed that NaOH was more efficient as compared to NaNO3 . The results on MR showed that all parameters were significant and applied voltage was found to be the most influencing parameter (70.14%). Field emission scanning electron microscopy (FESEM) and debris analysis were further carried out to study the performance of the ECDM process.
