Arrayed micro rod has many applications in current technology like, printer heads, medical devices, micro heat sinks, etc. Many studies highlighted capability of RMEDM for fabrication of these features. From exhaustive literature it has been found that in every variant of RMEDM the pre-processed tool has prime requirement as the process is a replication of electrode features on work piece. Hence, pre-processing of tooling has direct influence on costing and time. In the present study, the feasibility of readily available micro wire masks has been studied. The array of square rods of 200 µm side and 600 µm lengths were successfully generated on 4 mm bulk rod of brass. The effect of process parameters like Voltage, Capacitance and feed rate on machining time is investigated. L 18 full factorial design is used for the experimentation. Analysis of variance (ANOVA) results were used to observe the influence of factors on overall machining and found the highest influence of Voltage followed by Capacitance. Scanning electron microscope (SEM) has been used to characterize the fabricated surface.
