Parametric Study and Experimental Investigation of Material Removal Capability with Ultrasonic Assisted Electric Discharge Machining

Abstract

The development of modern materials has caused the exposure of metal matrix composites (MMCS). A metal matrix composite (MMC) is a composite material with at least two constituent parts, one necessarily metal, and the other may be a different metal or another material, such as a ceramic or organic compound. Carbon fibers are commonly used in the aluminum matrix to integrate composites showing high strength and low density.Non-conventional machining process Electrical discharge machining (EDM) is for machining electrically conductive materials.This research illustrates the effect of input variables (voltage, peak current, pulse on time, pulse off time) on output parameters like material removal rate, surface roughness, and electrode/Tool wear ratio (TWR).The results will show the relationship between input variables with responses which is obtained from Design of Experiments (DOE).
