Abstract

This paper investigates the effects on the rate of material removal of the frequency and amplitude of the ultrasonic vibration of the tool used in ultrasonic-assisted electrical discharge machining. It is shown that increases in the amplitude and frequency of the tool vibration increase the rate of pressure drop inside the bubble and consequently increase the rate of pressure drop on the surface of the workpiece. The latter facilitates the escape of the molten material from the crater and consequently increases the rate of material removal from the workpiece.
