Journal of The Japan Society of Electrical Machining Engineers, 2011 In this paper, methods of obtaining fine-finish surfaces in wire electrical discharge machining are discussed. Some countermeasures to reduce the stray capacitance of wire EDM, which restricts the surface roughness on an EDMed surface, are described. A surface roughness of 0.6[μm] Rz is obtained using a 0.1[μs] pulse width group type AC pulse generator.

Composite Wires with High Tensile Core for Wire EDM [PDF]
CIRP Annals, 2004 Abstract In recent years wire EDM cutting speeds and final surface roughness have been continuously improving. Much higher cutting speeds during roughing and surface roughness values lower than 0.1 μm Ra during finishing can be obtained. These enhancements are mostly attributed to the use of more advanced generator technology, but also to the type of
