Computer simulation of wire-EDM taper-cutting
International Journal of Computer Integrated Manufacturing, 2006Wire electro discharge machining (WEDM) has become one of the most popular processes for producing precise geometries in hard materials, such as those used in the tooling industry. Since it is recognized as a precision process, optimization of different aspects related to dimensional accuracy is a classic research topic.

High-Precision Wire-EDM by Online Wire Positioning Control
CIRP Annals, 1994The paper deals with a technical realization to improve the Wire EDM accuracy. The system which is readily available on commercial wire EDM machines is based on the on-line tracking and control of the wire position. The deviation of the wire position relative to the programmed wire path position is continuously measured and corrections are being made ...

Analysis of electromagnetic force in wire-EDM
Precision Engineering, 2009This paper clarifies the mechanism of how electromagnetic force applied to the wire electrode in wire electrical discharge machining (wire-EDM) is generated. This electromagnetic force is caused not only by DC component but also by AC components of the discharge current supplied to the wire.

Prevention of wire breakage in wire EDM
International Journal of Machining and Machinability of Materials, 2011This paper compares the performance of brass wire and zinc-coated wire on wire electro discharge machining (EDM) of high speed steel (HSS) material. For both types of wire the current, duty cycle, pulse-on time and wire speed have been selected as the input variables while the cutting rate, surface roughness and frequency of wire breakage as the output
