Abstract

In the modern era, the prime focus of researchers and industries is to develop new machining technologies and to improve the performance of existing machining processes. Ultrasonic-assisted Electrical Discharge Machining (UAEDM) is a hybrid machining process in which ultrasonic vibrations imparted either to tool electrode or workpiece improve the material removal mechanism by effective flushing of debris particles from machining area. In this paper, an attempt has been made to combine the Electrical Discharge Machining (EDM) with ultrasonic machining. In order to do so, a setup for imparting ultrasonic vibration to workpiece is developed and experiments have been performed to study the effect of EDM input parameters and ultrasonic vibrations on process performance of EDM. Copper is selected as tool material and Titanium grade 5 alloy (Ti6Al4V) is selected as workpiece material. From experimental analysis, it has been observed that low-frequency ultrasonic vibrations supplied to workpiece material improve the material removal rate (MRR) of Electrical Discharge Machining (EDM) process in considerable amount.
