Russian Engineering Research Aims and scope

Abstract

On the basis of experimental data, recommendations are made regarding the electric-discharge machining (EDM) of 38Х2Н2МА alloy-steel parts with improved high-temperature wear resistance. Those recommendations ensure high quality of the machined surface with the highest possible productivity. In the finishing pass, to ensure roughness Ra = 2.4, the following parameters are chosen: voltage U = 100 V; time of pulse action T = 150 µs; and current I = 6 A.
