Wire tension in high-speed wire electrical discharge machining

The International Journal of Advanced Manufacturing Technology, 2015
This 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

System Identification of Wire Electrical Discharge Machining

CIRP Annals, 1998
Abstract In wire electrical discharge machining (wire-EDM), it is very important to restrain the vibration of the tool wire electrode for the improvement of machining accuracy. In this paper, investigation is carried out toward the dynamic wire vibration mechanism and a mathematical model is derived.

Surface Roughness at Wire Electrical Discharge Machining

Applied Mechanics and Materials, 2015
Wire 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 vibration, bowing, and breakage in wire electrical discharge machining

Journal of Applied Physics, 2001
This 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.

High Speed Wire Electrical Discharge Machining*/High-Speed Wire Electrical Discharge Machining - An explorative study of a hybrid electro machining process

wt Werkstattstechnik online, 2016
Diese Untersuchung beschäftigt sich mit einer in den westlichen Industrienationen kaum bekannten Variante des Drahterodierens. Es wird zunächst ein Überblick über die Merkmale der Technologie (beispielsweise Aufbau, verwendeter Draht, Prozessflüssigkeit) gegeben, die sich teilweise deutlich von der konventionellen Technik unterscheiden.

Interelectrode discharge mechanism in high-speed wire electrical discharge machining

The International Journal of Advanced Manufacturing Technology, 2015
Different from conventional electrical discharge machining (EDM), given that the dielectric fluid utilized in high-speed wire EDM (HSWEDM) has a certain conductivity, a passive film can form on the workpiece surface because of the electrochemical reaction during processing. Such formation affects the interelectrode discharge characteristics.

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 ...

Wire-Cut Electrical Discharge Machining of Polymer Composites

Russian Engineering Research, 2021
Wire-cut electrical discharge machining (EDM) of VKU-39 polymer composite by means of conducting layers is considered. By that means, complex polymer-composite components may be machined with specified accuracy. On that basis, the options for the manufacture of polymer-composite components—including small components—may be expanded. Wire-cut electrical

An Overview of Wire Electrical Discharge Machining (WEDM)

2021
WEDM 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.
