During the manufacturing process Electrochemical Machining (ECM) a specific change in the workpiece geometry is generated by anodic dissolution of electrically conductive, usually metallic workpieces. Advantages of the electrochemical machining are mainly the large achievable removal rate and the low influence of material microstructure on the workpiece.
An innovative manufacturing technology is the use of closed electrolytic free jets (Jet-ECM). These enable a strong localisation of the removal area by good electrolyte supply.
Within this project, the production-technical bases of the Jet-ECM will be investigated. Conditions should be created for specific interpretation and application of this process, particularly in terms of effectiveness, geometric accuracy and the ability of miniaturisation, by systematic experimental work, and comparing the results with FEM simulations.
