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; counting the number of voltage pulses applied; counting the number of voltage pulses applied to the or each electrode which drop to below a threshold voltage; calculating the proportion of voltage pulses applied per electrode which drop to below the threshold voltage to the number of voltage pulses applied to yield an efficiency measurement for the or each electrode; outputting the efficiency measurement for the or each electrode; and adjusting the applied voltage pulses to the or each electrode according to the efficiency measurement to compensate for irregularities occurring in the or each electrode.
