Influence of the wire EDM conditions on the cut width

Resumo

The influence of the conditions of wire electric-discharge machining (EDM) on the cut width in the machining of 09G2S steel is experimentally investigated. The relation between the cutting power and the cut width is obtained. It is shown that, with reduction in the power, more thermal energy is concentrated at the machined section of surface, the probability of secondary spark discharges increases, and consequently the cut width increases.
