Micro-Machining and EDM processes

EDM-Processes I - Die sinking

In the micro-machining group mainly die sinking- and drilling processes in the meso- / micro-area (0.5 to 5 mm2 electrode cross-section area) are investigated.  The principal topic  is the widely preservation of the electrode shape over the whole deep of sinking.
Also EDM-processes are mathematically modelled and simulated.


EDM-Processes II - Drilling

The efficiency and the thermal integrity of high power gas turbines can be improved by cooling of the turbine blades. Therefor cooling air holes are drilled into the blades. The challenge for this process are once the difficult to machine material (nickel based steels) and the flat-angle of the bores to the surface. The EDM-drilling process covers both demands.
