State of the art in wire electrical discharge machining (WEDM)

International Journal of Machine Tools and Manufacture, 2004
Abstract Wire electrical discharge machining (WEDM) is a specialised thermal machining process capable of accurately machining parts with varying hardness or complex shapes, which have sharp edges that are very difficult to be machined by the main stream machining processes.

Machining of low electrical conductive materials by wire electrical discharge machining (WEDM)

Journal of Materials Processing Technology, 2004
Abstract This theoretical and experimental study of WEDM of low conductive materials demonstrates that total electrical resistance between the workpiece and wire electrode vary during machining depending upon the clamping position. This change in resistance causes a change in material removal rate (MRR) and average surface roughness that leads to ...

Experimental investigations of a hybrid machining combining wire electrical discharge machining (WEDM) and fixed abrasive wire saw

International Journal of Advanced Manufacturing Technology, 2017
WEDM and fixed abrasive diamond wire saw are two widely used technologies for cutting silicon ingot in semiconductor industry. When semiconductor is sliced by using WEDM method, although the wire electrode is in contact with workpiece, the processing can still be carried on. This phenomena is different from when the metal is sliced.
