In this investigation, the material removal rate, tool wear rate and surface integrity obtained by EDM, ultrasonic vibrations assisted EDM and magnetic field assisted EDM were studied and compared with together to show the quality of the effects of applying each of ultrasonic vibrations to tool and magnetic field around gap distance of EDM process on material removal rate, tool wear rate, and s...

Electrical discharge machining (EDM) process is one of the most commonly used nonconventional precise material removal processes. Electrical discharge machining (EDM) is a process for shaping hard metals and forming deep complex shaped holes by arc erosion in all kinds of electroconductive materials. Erosion pulse discharge occurs in a small gap between the work piece and the electrode. This re...

Electro Discharge Machining (EDM) is a noticeable machining practice among created unconventional machining procedures for intricate, complex profiles in "hard to machine" materials, similar to heat-treated steels, composites, superalloys, ceramics, composites, carbides, and so on. In EDM, the material expulsion of the cathode is accomplished through precise controlled electric discharge (the s...

Electro Discharge Machining (EDM) is a very efficient machining process widely used in manufacturing components of complicated geometry. Based on its nature, i.e. material removal by electric discharge, the process induces thermal stresses that in turn result in generation of wide spread micro-cracks on the surface of the machined part. In this paper the influence of EDM characteristic paramete...

There is a huge demand in the production of microstructures by a non-traditional method which is known as Micro-EDM. Micro-EDM process is based on the thermoelectric energy between the workpiece and an electrode. Micro-EDM is a newly developed method to produce micro-parts which in the range of 50 μm -100 μm. Micro-EDM is an efficient machining process for the fabrication of a micro-metal hole ...

This study investigates the dry and near-dry electrical discharge machining (EDM) milling to achieve a high material removal rate (MRR) and fine surface finish for roughing and finishing operations, respectively. Dry EDM uses gas and near-dry EDM applies a liquid-gas mixture as the dielectric medium. Experimental studies leading to the selection of oxygen gas and copper electrode for high MRR d...

Electronic document management (EDM) relates to several modern information technologies. Little research on methods for practical development of EDM exists. Such method, based on the genre theory of organizational communication, was adopted by a team of EDM consultants who used and engineered it further along with their customer cases for developing EDM systems. These experiences were gathered ...

The electric dipole moment (EDM) of paramagnetic atoms is sensitive to the intrinsic EDM contribution from that of its constituent electrons and a scalar-pseudoscalar (S-PS) electron-nucleus interaction. The electron EDM and the S-PS contributions to the EDMs of these atoms scale as approximately Z;{3}. Thus, the heavy paramagnetic atoms will exhibit large EDM enhancement factors. However, the ...
