Micro-EDM is an extensively used micromachining process to fabricate microcavities on metallic surfaces. Material erosion in micro-EDM is realized by imparting controlled sparks between electrodes submerged under the dielectric fluid. Recently, micromanufacturing is in demand and resulted in miniaturization of switches, screws, gears, shafts, and other

Energetic Modeling of a Micro-EDM Machine
Proceedings of the 10th International Conference on Multi-Material Micro Manufacture, 2013The energetic model of a micro-EDM machine is presented. The model considers the energy required by the axis drivers, the micro-EDM generator, the air compressor and the chiller of the dielectric fluid. The model parameters have been experimentally identified during the micro-EDM machining of a blind hole.

Generation of Microelectrodes for Micro EDM
Key Engineering Materials, 2012A new turning method to control the thrust force to be zero has already been proposed in our laboratory, and it is shown that micro shafts which diameters are less than 1 mm can be generated stably and repeatedly by applying this turning method. As an application of this turning method, a generating method of electrodes of micro electric discharge ...

Generation of Microelectrodes for Micro EDM
Key Engineering Materials, 2013In order to fabricate micro holes by EDM process, microelectrodes with high accuracy of form are needed. At present, micro electrodes are generated by grinding and/or on-machine EDM operations and then it is well known that efficient productivity of micro electrodes cannot be realized.

Micro-EDM for silicon microstructure fabrication
SPIE Proceedings, 1999Currently, most silicon microstructures used in microstructures are produced by photolithographic methods. The reason for this is the well-developed etching technology, used in microelectronics, that has been transferred to the microsystem domain. But since the making of an arbitrary shape or angle on silicon mainly depends on the crystal orientation ...
