Measurement of wire electrode temperature in WEDM

The International Journal of Advanced Manufacturing Technology, 2008
Wire 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.

Machining phenomena in WEDM of insulating ceramics

Journal of Materials Processing Technology, 2004
Abstract 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,

High Precision Finish Cutting by Dry WEDM

CIRP Annals, 2001
Abstract This paper describes the development of a new dry wire electrical discharge machining (dry-WEDM) method, which is conducted in a gas atmosphere without using dielectric liquid to improve the accuracy of finish cutting. In dry-WEDM, the vibration of the wire electrode is minute due to the negligibly small process reaction force.

Improving Process Characteristics of Dry-WEDM

2002
This paper describes the first attempt to conduct rough-cutting with dry wire electrical discharge machining (dry-WEDM). With the dry method, there is no corrosion, and edges can be cut more sharply than the conventional method. One drawback of the dry method however is the lower material removal rate compared to the conventional method. Moistened wire

Microstructural characteristics of pure titanium by WEDM

International Journal of Microstructure and Materials Properties, 2014
In this research work pure titanium was machined with WEDM process with zinc coated wire electrode having O0.25 mm. Experimentation was conducted as per Taguchi's L27 orthogonal array for investigating the influence of process parameters such as pulse on time (TON), pulse off time (TOFF), peak current (IP), wire feed (WF), wire tension (WT) and servo ...
