Online published on 4 March, 2016. Abstract This research is mainly focused to develop a sparkgap controller for tabletop micro EDM setup and evaluating the performance in terms of micro hole drilling. To assess the performance of the controller, 27 experiments were conducted using full factorial design methodology. The input parameters of micro EDM operations such as voltage, capacitance and sparkgap were considered for experimentation to find out the Material Removal Rate (MRR). The experimental result shows that the voltage makes the major contribution and sparkgap provides minor contribution than capacitance and the performance of the developed sparkgap controller is satisfactory in micro EDM operations.
