Verfahren zum elektro-chemischen Bearbeiten eines Werkstücks und Elektrode für ein solches Verfahren

The invention concerns a method for processing a work piece ( 21 ), in which a work piece ( 21 ) is constructed in layers ( 3 ) from a conductive material using a rapid prototyping process. The work piece ( 21 ) constructed in layers ( 3 ) is contacted in an anodic manner. Then, a tool ( 1 ) is disposed opposite to a to-be-processed site of the work piece ( 21 ) such that a gap ( 50 ) remains therebetween. The tool ( 1 ) is contacted in a cathodic manner and a conductive medium ( 32 ) is brought into the gap ( 50 ) so that current flows by applying an electronic voltage and metal ions are dissolved from the work piece ( 21 ) by electrolysis, whereby a defined removal of material from the work piece ( 21 ) takes place. The invention further concerns a method for producing a tool to be utilized as an electrode ( 1 ) in an ECM method and an electrode ( 1 ) for usage in an ECM method for electro-chemical processing of a work piece ( 21 ).
