In the Winter 2008 issue of MICROmanufacturing, I discussed the novel idea of using EDM discharge dressing to shape and size electrodes for microholemaking. This process has several advantages for certain applications compared to centerless-ground and extruded EDM electrodes, as well as conventionally ground and turned electrodes.
In this issue I show how this process works in microholemaking, comparing the outcomes with other holemaking processes.
