State of the art in wire electrical discharge machining (WEDM)
International Journal of Machine Tools and Manufacture, 2004Abstract 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.

Wire electrical discharge machining (WEDM) analysis into MRR and SR on copper alloy
Materials Today: Proceedings, 2020Abstract Wire electric discharge machining (WEDM) is a widely accepted non-traditional material removal process for manufacturing of components with intricate shapes. Wire electric discharge machining is assessed on basic of metal removal rate (MRR) and surface roughness (Ra).

Machining of low electrical conductive materials by wire electrical discharge machining (WEDM)
Journal of Materials Processing Technology, 2004Abstract 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 ...

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.

AbstractThe high capital costs of wire electrical discharge machining (WEDM) equipment necessitate optimal utilization of the WEDM process and equipment. Cutting speed (CS) is a key performance measure to achieve this objective. However, process parameters of WEDM greatly hamper CS and hence productivity and machining efficiency.
