Abstract

The paper deals with a comparative study of superficial layer of CoCr alloys obtained at classic and ultrasonic (US) aided electrical discharge machining (EDM). The machined materials characteristics, the equipment used at laboratory experiments, the working values and the most relevant images of superficial layer provided by scanning electron microscope are presented. Comparative numerical simulation of discharges in case of EDM and EDM+US and their effect on the superficial layer were validated by experimental data. An economic model for evaluation of EDM+US performances was elaborated.
