Abstract
Due to its thermal principle allowing an almost force free machining intependend of the material's mechanical properties, electrical discharge machining (EDM) is a well established production technique for manufacturing micro holes. especially when machining ceramics, a material group that is predestined for the application within the field of micro technology, EDM is of increasing importance. However, the production of precise micro holes with complex geometries and high aspect ratios is associated with a lot of challenges. High tool electrode wear, a small material removal rate and the increasing importance of flushing at high aspect ratios and small gap widths can be observed during this machining process.
