In the present investigation Al/20Al2O3p composite has been fabricated by stir casting method. Al2O3 particles containing weight fraction 20 wt% and mesh size 400 are used as reinforcement. Though Al/Al2O3 MMCs possess superior mechanical properties, its high abrasiveness hinders the machining process and thereby limiting its effective applications in several areas. In the present work, One Parameter at a Time (OPAT) approach has been used to analyze the process behavior of Electrical Discharge Drilling during the fabrication of hole in aluminum alloy based MMC using copper tool electrode of 6 mm diameter. The effect of input process parameters namely discharge current (C), pulse duration (Ton), pulse interval (Toff), flushing pressure (P), and tool rotation (RPM) were analyzed on output performance characteristics of Material Removal Rate (MRR), Kerf Taper (T), and Radial Overcut (ROC). Brief detail about the fabrication of Al2O3/6061Al MMC has also been discussed.
