In this work an attempt has been made to correlate usefulness of electrodes during rotary motion. Experiments are conducted to study the effect of different parameter such as peak current and duty cycle on material removal rate and surface finish while using different rotary electrode such as Copper, Brass and Aluminium. It is observed that using rotary copper electrode for electric discharge machining at low and intermediate values of peak current i.e. 10 and 20A to provide better MRR than that of aluminium and brass at duty cycle 3 and 9 whereas, for high value of peak current i.e. 30A aluminium to be used. At duty cycle 6 aluminium has better MRR at low and intermediate value of peak current i.e. 10 and 20A whereas, copper is used for high value of current i.e. 30A and brass is not acceptable at any value of current and duty cycle because of its poor MRR. SR has lowest value when we use brass electrode for every set of duty cycle. e percentage contribution of input parameter has been calculated using ANOVA table. It showed that current has the maximum effect on all parameter followed by duty cycle and on time.
