Study on the effect of electrical parameters and the powder concentration on surface roughness of the thermal treatment skd61 by electrical discharge machining with tungsten carbide powder =

Abstract

In the study, the authors studied the effect of the electrical current (Ip) the time on discharge (Ton) and tungsten carbide powder concentration on the surface roughness of the thermal treatment SKD61 by electrical discharge machining with tungsten carbide powder mixing in the oil dielectric. Based on experimental results, the elaboration of surface roughness formula is related to the technological parameters and powder concentration. Research has investigated the effect of electrical current (Ip); the time on discharge (Ton) and the concentration of powder to the roughness of surface.
