Ultrasonic Vibration Assisted Electrical Discharge Machining and Micro-Electrical Discharge Machining: A Review

Machining science and technology, 2023
Material is removed during electrical discharge machining (EDM) because of the high temperatures. Hence, tiny components of the tool and workpiece melt and evaporate, causing molten metal to solidify and form debris.

Analysis of Electrical Discharge Machining

Technical Physics, 2019
Breakdown in liquid dielectric medium, plasma channel, and heat transfer in the course of electrical discharge machining are studied. Specific features and most important parameters of electrical discharge machining of titanium and aluminum alloys are determined. Theoretical, experimental, and simulated results indicate that the adequacy hypothesis can

Surface Destruction in Electrical Discharge Machining

Russian Engineering Research, 2021
In electrical discharge machining, the formation of the modified surface layer depends on the physicochemical properties of the anode and cathode and the machining conditions. Experiments show that the mass transfer and coating thickness decrease with increase in thermal conductivity and decrease in melting point of the anode and cathode.

Electrical Discharge Machining

2015
The machining processes introduced in the previous chapters center around the generation of relative motion between the workpiece and the wedge-shaped cutting tool. In these traditional processes, the fundamental mechanism responsible for the removal of materials is the plastic shearing action along the shear plane.

Electrical Discharge Machining in Gas

CIRP Annals, 1997
Abstract In this paper, we show that electrical discharge machining (EDM) can be achieved in gas. With the help of a high-pressure gas flow supplied through a thin-walled pipe electrode, the molten workpiece material can be removed and flushed out of the working gap without being reattached to the electrode surfaces.

Electrical Discharge Machining

2012
Electrical discharge machining (EDM) is considered suitable for machining materials that are extremely hard or strong, and are wear or temperature resistant. In Chap. 2, we outline EDM characteristics of carbon fiber-reinforced carbon composites and AISI D2 tool steel. This article is organized as follows: first, the effects of EDM processing variables

Electrical discharge machining with ultralow discharge energy

Precision Engineering, 2006
The possibility of electrical discharge machining (EDM) with ultralow discharge energy has been investigated. EDM using an RC discharge circuit was performed at low open-circuit voltages and a capacitance of approximately 30 pF. Workpieces were ultrasonically vibrated to remove debris and bubbles from the discharge gap, thus preventing short-circuiting.
