Abstract

A new method for improving the EDM (electrical discharge machining) performance of a Ti-6Al-4V alloy is investigated. The experimental results indicate that the best overall performance is achieved using ultrasonic vibration dielectric. The improvement mechanism is that the ultrasonic vibration results in the restraining of discharge concentration and the formation of small debris. It is also found to be effective for promoting the machined surface roughness to use ultrasonic vibration dielectric suspended with electrically conductive powder such as pure aluminum powder.
