GEOMETRIC CONTROL AND BEST FITTING OF ELECTRIC DISCHARGE MACHINING TOOLS

摘要

A method for checking a geometry of an electric discharge machining electrode (11) is described. The method comprises the following steps: • providing a file containing a native 3D-model (21) of the electric discharge machining electrode; • providing a manufactured electric discharge machining electrode (11) 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 (23) of the manufactured electric discharge machining electrode; comparing the native 3D-model (21) and the scanned 3D-model (23) and generating electrode compensation coordinates for an electric discharge machining apparatus, to correct an electrode path during electric discharge machining.
