چکیده
Among all non-conventional micro-machining, electrochemical discharge machining (ECDM) is having high quality of material removal rate with zero residual stress. This machining has been accepted as a highly modern technology in micromachining. In this paper an effort has been done on micro drilling of glass using electrochemical discharge machining (ECDM). A fixed tool and a step down transformer have been used to support the steady machining to increase the accuracy of work piece. The input parameters used in this experiment are voltage, concentration of electrolyte, enterelectrode gap and ratio of area of electrode. MRR has been investigated over the input parameters. Feed rate and electrolyte temperature has been made constant of 3μm/sec and 30 ̊c respectively. Taguchi method is used to optimize the effect of the process parameters on MRR. The signal to noise (S/N) ratio and the ANOVA analysis are employed to find the contributions of input parameters. Keywords-Electrochemical Discharge Machining (ECDM), Taguchi Technique, ANOVA, Material Removal Rate (MRR), Sound vs. Noise (S/N) ratio.
