Wire electrical discharge machining for microfabrication

This paper discusses the application of conventional wire electrical discharge machining (WEDM) for fabrication of miniaturized components using low pulse energy. The surface finish of the fabricated microparts was investigated for different level of discharge current at constant gap voltage and p...
