In the electric discharge machining system, the determination of the gap between the anode and the cathode is a difficult point of this kind of machining approach. An accurate mathematical model of interelectrode gap is obtained, and the precise control of the gap is achieved on this basis. In this paper, based on the example of discharge machining of P-type single crystal Si, the theoretical analysis proved that the discharge channel can be equivalent to pure resistance, and the physical model of the interelectrode gap and voltage and current was established.

We propose an improvement of dielectrophoresis technique (DEP) by designing, simulating and experiment a 20 μm interelectrode gap for Staphylococcus aureus rapid detection application. In this paper, we use MyDEP simulation for DEP polarization Staphylococcus aureus on frequencies range. COMSOL simulation is utilized for comparison of 20 μm and 80 μm interelectrode gap based on trajectory and velocity of particles for Staphylococcus aureus application. We implied 20 μm interelectrode gap for Staphylococcus aureus application produced higher magnitude DEP force. Which gives accurate trajectory

In this paper, an experimental study and simulation in the Simulink graphical environment of the interelectrode gap during electroerosive grinding with changing polarity of electrodes of difficult-to-machine materials was carried out. Based on the experimentally obtained oscillograms of currents and voltages in the cutting zone, a simulation model of the interelectrode gap has been developed. The model implements a nonlinear dependence of the active resistance of the interelectrode gap on its value, which makes it possible to take into account the influence of the interelectrode medium on the

The electric discharge machining (EDM) interelectrode gap directly determines the discharge state, which affects the machining efficiency, workpiece surface quality, and the tool wear rate. The measurement of the real-time varying interelectrode gap during machining is extremely difficult, and so obtaining an accurate mathematical model of the dynamic interelectrode gap will make EDM gap control possible. Based on p-type single-crystal silicon EDM, a flat-plate capacitance model is introduced to analyze the time-domain characteristics of the inter-electrode voltage in the breakdown delay phase

AbstractDynamics of the initial stage of discharge in air is studied at atmospheric pressure in a point–plane gap at different parameters of the tip electrode and lengths of the interelectrode gap. Spark or diffuse discharges are implemented in experiments depending on the length of the interelectrode gap. Shadow photography is used to show that, for all electrodes in the experiments, the discharge channels represent multiple microchannels that develop from the tip and close the discharge gap.

Electrochemical micromachining (ECMM) is a non-conventional manufacturing method suitable for the production of microsized components on a wide range of conductive materials. ECMM improves dimensional accuracy and simplifies tool design for machining hard, high strength, heat resistant, and conductive materials into complex shapes. Extremely small interelectrode gaps of the order of few microns are required in ECMM for better dimensional accuracy. However, excessively small interelectrode gaps may lead to complications, such as short-circuiting, which disrupt the stability of ECMM process. Thi

In this work, the effect of physical parameters on the yield of fullerene synthesized in a hollow cathode plasma reactor is investigated. The experimental investigations done previously have shown that the fullerene yield depended on technical parameters - the current intensity, inert gas pressure, type of gas and interelectrode gap. The aim of this work was to show that the fullerene yield depends on physical parameters - carbon concentration, carbon flow rate from the interelectrode gap, axial temperature and temperature gradient between the are channel and the chamber walls as well. It was

Electrical, optical and polarization characteristics of nanosecond discharges in the short interelectrode gap have been experimentally researched. The conditions and mechanisms of accelerated electrons formation are established. The estimates of energy, the length of accelerated electrons run and electron beam generation efficiency in the investigated discharge are obtained. The formation of electron beams is confirmed by the studies of polarization of spontaneous discharge irradiation.

An analysis is made of interfering factors, such as base surface roughness and partial discharges, which can affect the process of continuity testing by the electrospark method, reducing the breakdown voltage of the interelectrode gap and leading to false alarms. To consider the influence of the coating base surface roughness, the distribution of the electric field in the system of two electrodes with a given roughness was constructed in the Ansys Electronics Desktop program. An experiment was carried out to determine the breakdown voltage of the air gap for different values of the surface rou

Aluminum-based ceramics exhibit excellent wear resistance and hot hardness that are suitable for various responsible applications allowing products to work under extreme mechanical and thermal loads (up to 1000 °C). The problem of high-precision forming complex-shaped parts is a known engineering challenge due to the insulating properties of aluminum-containing ceramics and the formation of chemically active carbides in a hydrocarbon medium. The alternative approach for electrical discharge machining non-conductive sintered Al2O3 in the water-based medium using nickel-chrome plasma-vapor-depos

Modern enterprises use various equipment for the production of rods, for example, hydraulic presses for direct extrusion and metal cutting machines. However, this equipment is not used for the production of rods from hard-to-process materials. In this regard, EDM machines are of some practical interest, as they are more universal and reliable. Electroerosion machines that can be used for the manufacture of rods include electric spark machines, electric pulse machines and machines for dimensional processing by electric arc (ROD - dimensional processing by arc).

This paper considers some theoretical provisions on the impact ultrasonic mechanical vibrations have on the throughput of an electroerosive piercing of small-diameter holes. The approximate estimates confirm the hypothesis that the cumulative jets mechanism makes the greatest contribution to the intensification of a multiphase medium flow in the interelectrode gap. A model is proposed for a periodic localization of the cavitation region in the bottom part of the annular side gap. It allows explaining the occurrence of a multiphase medium flow during hole processing.
