Abstract
In the electrolyte jet machining (EJM), the electrolytic current between the anodic work piece and the cathodic nozzle is supplied via an electrolyte jet which is ejected from a nozzle. The main advantage compared to other EC-processes is, that the electrolytic current is restricted to a limited area by the jet. The removal amount and the machining position can easily be controlled by setting the electric current and the nozzle position. Compared to pulsed ECM, higher dissolution rates are possible, because simple direct current is applied. In this study, a three axis electrolyte jet machining system is used which is cooperatively controlled by a personal computer. The machining system was used to process complicated micro structures. In order to verify the machining results, FEM simulations of the dissolution process were made for simple pit geometries with the commercial software COMSOL Multiphysics-DTM. The simulated and the produced shapes show a good coincidence.
