This work involves the experimental study of drilling EDM parameters for Incoloy 800 alloy. Material erosion rate and tool wear rate has been considered as the response characteristics. Design of experimental runs were framed using CCD based response surface methodology. The experiments are performed in random manner with different combination of pulse current, spark duration, voltage and pulse interval and the results obtained are analyzed using Analysis of Variance (ANOVA). Various 3D plots are generated by using Design Expert software in this work. Discharge current and spark duration were found as the dominant variables for MRR and EWR and the effect is high on these two responses relative to other variables.
