TL;DR: In this article, a high precision tabletop CNC wire electrical discharge machine (wire EDM) designed specifically for machining complex shape micro parts or structures is developed, a novel micro-wire-cutting mechanism is designed, an approach to control wire tension by magnetic force is proposed and a servo feed control strategy, in accordance with the measured gap voltage, is designed and implemented.

TL;DR: The advanced diamond dresser (ADD) as discussed by the authors is made by sculpting a polycrystalline diamond substrate to form identically shaped tips with diamond pieces of equal height, rather than by attaching individual diamond grits to a metal substrate.

TL;DR: In this paper, a micro-diamond tool with a diameter of 100μm was proposed for precision and micro-grinding during miniature die machining, which can be applied to dental drilling tools, precision optic dies, molds and tools, and biomedical instruments.

TL;DR: In this article, a machining technique to fabricate high aspect ratio microstructure arrays of a total volume less than 1 mm3 is developed, and a method for determining the appropriate tension of the micro brass wire of the reverse wire-EDM mechanism designed in our previous study is implemented.

TL;DR: In this paper, an inexpensive machining approach for producing a batch of micro holes is proposed, where a set of previously introduced w-EDM mechanisms is employed to horizontally cut the batch micro electrodes precisely.
