Electrode Wear Process in Electrical Discharge Machinings
CIRP Annals, 1995Abstract This paper deals with a synthetic consideration of electrode wear phenomena in electrical discharge machining. Time dependance of an electrode shape was observed through on-the-machine measurement. While the electrode wears at the edge portion in the beginning of machining, it grows at the flat portion in the longitudinal direction.

Electrode wear protection mechanism in meso–micro-EDM
Journal of Materials Processing Technology, 2015Abstract A carbonaceous layer builds up on the electrode surface in electrical discharge machining (EDM) when using low wear settings. Current paper investigates the carbonaceous layer and its formation during the erosion. It is found that a diamond like amorphous carbon layer embedded with the micro and nanosized metallic debris from the work-piece ...

A strategy for low electrode wear in meso–micro-EDM
Precision Engineering, 2015Abstract Implementation of die-sinking EDM for precision machining of meso–micro-scale features with surface area smaller than 10 mm 2 down to 0.1 mm 2 is mainly restricted by electrode machining and electrode wear. In this work, micro-scale graphite electrodes with a projection area as small as 0.002 mm 2 and 1 mm length have been machined ...

Miniaturized electroencephalographic scalp electrode for optimal wearing comfort
Klinische Neurophysiologie, 2010Current mainstream EEG electrode setups permit efficient recordings, but are often bulky and uncomfortable for subjects. Here we introduce a novel type of EEG electrode, which is designed for an optimal wearing comfort. The electrode is referred to as C-electrode where "C" stands for comfort.The C-electrode does not require any holder/cap for fixation ...

Electrode wear pattern during EDM milling of Inconel 718
The International Journal of Advanced Manufacturing Technology, 2021Electrical discharge machining (EDM) is a well-known process, which is distinct from conventional machining methods thermal machining principle not susceptible to materials hardness and therefore is mainly used for difficult-to-cut materials. EDM milling is a relatively new method to machine complex geometries by using standard shape, cylindrical ...

Electrode Tool Wear at Electrical Discharge Machining
Key Engineering Materials, 2012As consequence of the development of electrical discharge machining process, the electrode is affected by wear; knowing the evolution of the electrode wear, a better estimation of its service life is possible. It is expected that the electrode wear depends on the energy of the electrical discharges and the mass of the electrode.

Wear of refractory tool electrodes in electromachining
Soviet Powder Metallurgy and Metal Ceramics, 19751. A study was made of the contact phenomena occurring during the electromachining of the transition metals with some refractory compounds (carbides and borides). The relationships between tool electrode wear and the moduli of elasticity and thermal conductivities of materials machined are examined.

Study of Tool Electrode Wear in EDM Process
Key Engineering Materials, 2015Technology of Electrical Discharge Machining (EDM) uses thermal energy in material removal, in which is the electrical energy transformed, generated between the electrodes (tool and workpiece). The material removal occurs through the rapid periodic repetitive electrical discharges in the presence of dielectric fluid.

Super Ignition Spark Plug with Wear Resistive Electrode
SAE Technical Paper Series, 2008<div class="htmlview paragraph">Ever since the creation of the spark plug, improvements have continually been made to achieve high ignitability and long life. To fulfill these requirements, “Iridium Spark Plug” was introduced in 1997 with fine-wire center electrode technology to promote ignitability and long life.

Wear of tool electrodes in electromachining
Soviet Powder Metallurgy and Metal Ceramics, 19701. A study was made of the wear of VK and TK type sintered hard alloys during the electromachining of Armco iron and steel 3, 45, U8, and ShKh15 steels. 2. It was established that, generally speaking, the highest wear resistance is exhibited by the VK group of hard alloys, whose wear is essentially due to adhesion.
