Measurement of wire electrode temperature in WEDM
The International Journal of Advanced Manufacturing Technology, 2008Wire temperature is an important parameter in the wire electro-discharge machining (WEDM) process because overheating of the wire can cause the wire to break. It is difficult, however, to measure the wire temperature directly under the condition that the wire is emerged in water and surrounded by the workpiece.

Performance evaluation of WEDM by application of MOGA
Materials Today: Proceedings, 2020Abstract The phenomenon of spark erosion for forming complex profiles on conductive materials is applied in WEDM. In current research D3 die tool steel is assessed in terms of two conflicting responses i.e. surface roughness (Ra) and material removal rate (MRR).

ANN for Interpolating Instability Trends in WEDM
IFAC Proceedings Volumes, 2008Abstract In Wire Electrical Discharge Machining (WEDM) the breakage of the cutting tool (the wire) reduces the process performance and the required accuracy. Previous works of authors showed that the behavior of the basic signals of the process (current and voltage) can be employed to detect degraded situations that can lead to wire breakage.

Machining phenomena in WEDM of insulating ceramics
Journal of Materials Processing Technology, 2004Abstract Recently, an electrical discharge machining (EDM) method of insulating ceramics was proposed by the authors. This paper describes the arbitrary shape machining method of Si 3 N 4 insulating ceramics by WEDM. In the WEDM of thick workpieces of Si 3 N 4 insulating ceramics, wire breakages occurred frequently. To avoid the breakage conditions,

Large taper mechanism of HS-WEDM
The International Journal of Advanced Manufacturing Technology, 2016Large taper (≥ ± 5°) high-speed wire electrical discharge machining can be affected by many factors. The positioning error of wire electrode caused by guide wheels and the run-out of guide wheels are particularly important. Moreover, dielectric fluid cannot wrap the wire electrode appropriately and flow into the machining region along with the wire ...
