Process of forming conical holes with an electrical discharge machining system

摘要

An electrical discharge machine is configured to (i) machine at least a portion of a workpiece through electrical discharge between the workpiece and a first machining electrode aligned by the electrode guide; (ii) generate a dressed machining electrode by engaging a machining electrode aligned by the electrode guide with the electrode dresser; and (iii) machine at least a portion of a workpiece through electrical discharge between the workpiece and the dressed machining electrode. Additional electrical discharge machines and methods of machining are provided.
