TL;DR: In this article, a surface modification method by electrical discharge machining with a green compact electrode has been studied to make a thick TiC or WC layer, where the powder is suspended in working oil like kerosene and the use of a thin electrode and a rotating disk electrode are expected to keep powder concentration high in the gap between a workpiece and an electrode and to accrete powder material on the workpiece.

TL;DR: In this paper, a local actuator module was proposed to improve machining accuracy and speed for micro-dies and drilling micro-holes in electrical discharge machines, which achieved a fast frequency response of 200 Hz in each of the X -, Y - and Z -axes directions.

TL;DR: In this article, the authors apply voltage between an electrode of simple shape and a workpiece, performing three-dimensional control by an NC control while synthesizing a feed of a Z-axis direction for correcting longitudinal consumed amount of an electrode with an X-Y plane feed.

TL;DR: In this paper, a new method of surface modification by EDM to create a hard surface on the workpiece was described, where the worn electrode material is combined with carbon which is a constituent of dielectric fluid and becomes hard carbide.

TL;DR: In this article, the authors describe a high-precision millimeter-stroke actuator that is controllable in five degrees of freedom (5-DOF) to maintain a suitable distance between the electrode and the workpiece in electrical discharge machining.
