High-performance wire electrodes for wire electrical-discharge machining – a review
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2012In a wire electrical-discharge machining process an electrically conductive workpiece is eroded ahead of a continuous moving wire by spark discharges, which are identical with those in conventional electrical-discharge machining. With wire electrical-discharge machining, convoluted shapes can be cut with a high degree of dimensional accuracy and good ...

An Overview of Wire Electrical Discharge Machining (WEDM)
2021WEDM is not a traditional machining process. The process is based on a thermo-electrical energy system. In this process, any mechanical connection between the electrode (wire) and the workpiece is not required for cutting any object. To establish a contact within the wire and the work object, different dielectric fluids are used.

Surface Roughness at Wire Electrical Discharge Machining
Applied Mechanics and Materials, 2015Wire electrical discharge machining is a machining method by which parts having various contours could be detached from plate workpieces. The method uses the electrical discharges developed between the workpiece and the wire tool electrode found in an axial motion, when in the work zone a dielectric fluid is recirculated.

Wire tension in high-speed wire electrical discharge machining
The International Journal of Advanced Manufacturing Technology, 2015This paper investigated the wire tension change in high-speed wire electrical discharge machining (HSWEDM). The symmetry of the wire-winding mechanism and the resistance to the wire electrode on the upper and lower guide frames were considered the main causes of a non-even wire tension. Combined with the simulation model and the redesigned wire-winding

Wire vibration, bowing, and breakage in wire electrical discharge machining
Journal of Applied Physics, 2001This article provides an analysis of the wire electrical discharge machining (EDM) process. The causes of wire vibration, bowing, and breakage are identified. The cross sectional configuration of an eroded wire is derived from basic physics under the assumption that the erosion rate is constant.
