Abstract
A method for checking a geometry of an electric discharge machining electrode is described. The method comprises the following steps: providing a file containing a native 3D-model of the electric discharge machining electrode; providing a manufactured electric discharge machining electrode based on the native 3D-model; light scanning a set of images of the manufactured electric discharge machining electrode in different positions and generating therewith a scanned 3D-model of the manufactured electric discharge machining electrode; comparing the native 3D-model and the scanned 3D-model and generating electrode compensation coordinates for an electric discharge machining apparatus, to correct an electrode path during electric discharge machining.
