摘要：

This paper presents a machinability study by experimentally establishing the main process functions, termed as: machining productivity, relative volume wear and lateral gap for three Romanian steels OLC45, C120 and VCW85. Based on these process functions, there have been established the effects of principal process parameters on the technological characteristics of electrical discharge machining (EDM) of the above-mentioned materials. According to author's research, it has been determined that current intensity has the highest effect on machinability, followed by impulse duration t(i) and pause time t(0). To determine the effect of machined material on its machinability, the machinability indices were determined, using as reference material OLC45 steel, for two operation regimes, namely finishing and semi-finishing.
