description This thesis deals with optimization of micro Electrical Discharge Machining (EDM) drilling process using Taguchi method. EDM is a thermal process that utilizes spark discharges to erode a conductive material. The objective of this thesis is to study the effect of independent variable to accuracy of micro EDM drilling process and to optimize it by using Taguchi method. Taguchi Method is used to find the optimal drilling parameters for hole diameter in drilling operation. The orthogonal array, the signal-to-noise ratio, and analysis of variance are employed to study the performance characteristics in drilling operations of mild steel (50mm length x 75mm width x 5mm height) as workpiece by using 1mm copper (Cu) pipe electrode.

It is found that Taguchi’s robust orthogonal array design method is suitable to analyze the hole diameter problem.
