Abstract: In this paper, the machinability characteristics of hybrid metal matrix composites (HMMCs) (Al6063/SiC/Gr/Al2O3) have been experimentally evaluated during electro-discharge drilling (EDD) with solid and hollow tool electrodes made of copper and brass. The influence of different parameter such as (i) discharge current, (ii) tool material, and (iii) tool geometry on (i) material removal rate (MRR) and (ii) tool wear rate (TWR) has been experimentally investigated. The end face wear of the tool electrode has also been presented with the help of microscopy imaging. The results of the experimental investigation indicated that the MRR is improved with hollow brass tool electrode and TWR is reduced with solid copper tool electrode during EDD of developed composites.
