METHOD AND APPARATUS FOR IMPROVING ROLL TEXTURING USING ELECTRICAL DISCHARGE MACHINES

摘要

A control method for an electrical discharge apparatus wherein the electrical discharge apparatus is for applying a machined or textured finish to the surface of an electricity conductive workpiece comprising the steps of; applying multiple voltage pulses to one or more electrodes over a predetermined time period; monitoring voltage parameters output by the or each electrode; and adjusting the applied voltage pulses to compensate for irregularities occurring in the or each electrode. The workpiece may also be mapped to produce a textured pattern which map is used to control the pulse supply to the electrode(s).
