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.

Geometric control and best fitting of electric discharge machining tools

A machining system for machining a workpiece is provided. The machining system comprises a machine tool, a plurality of cutting tools, a CNC controller. The plurality of cutting tools comprises an electrode and a conventional cutting tool exchangeably disposed on the machine tool. The machining system further comprises a power supply, a process controller, and an electrolyte supply, wherein the machine tool, the electrode, the CNC controller, the power supply, the process controller and the electrolyte supply are configured to cooperate to function as an electroerosion machining device, wherein the machine tool, the CNC controller, the conventional cutting tool and the electrolyte supply are configured to cooperate to function as a conventional machining device, and wherein the machining system is configured to function alternately as the electroerosion machining device and the conventional machining device.

Machining systems and methods

A Method and machine tool for compensating a wear of an electrode that machines a workpiece. The method includes selecting a current pocket from plural pockets of the workpiece; updating a wear compensation to be applied to the electrode for the current pocket based on wear compensation of a previous pocket, where the previous pocket is adjacent to the current pocket; and applying the updated wear compensation to the electrode for machining the current pocket.
