Distributed arc electroerosion

摘要

An electroerosion apparatus (10) includes a tubular electrode (12) supported in a tool head (16) in a multiaxis machine (14). The machine (14) is configured for spinning the electrode (12) along multiple axes of movement relative to a workpiece (20) supported on a spindle having an additional axis of movement. A power supply (22) powers the electrode (12) as a cathode and the workpiece (20) as an anode. Electrolyte (30) is circulated through the tubular electrode (12) during operation. And, a controller (32) is configured to operate the machine (14) and power supply (22) for distributing multiple electrical arcs between the electrode (12) and workpiece (20) for electroerosion thereof as the spinning electrode travels along its feedpath.
