Abstract
Electric Discharge Drilling (EDD) is effectively used in modern manufacturing industries it is a thermo-electric non-traditional machining process. It has the potential to machine electrically non-conductive high-strength, high-temperature-resistant (HSHTR) ceramics. This paper investigates the influence of four different input parameters such as Pulse on time, Pulse off time, Distilled water pressure and Discharge current of electric discharge drilling performance of hole circularity, hole taper and hole dilation using Taguchi methodology. Titanium and its alloys have high demand in different industries due to their superior properties. Brass electrode was selected based on their electrical and thermal property. Experiments were carried out as per Taguchi’s L36 orthogonal array. Analysis of variance indicates that the pulse on time is more significant factor for hole circularity, distilled water pressure is more significant for hole taper and Pulse off time is more significant factor for hole dilation.
