Abstract

See full text

A device and a method for producing a blade airfoil from a workpiece which comprises at least two gaps and at least one blank arranged between the two gaps, wherein the blank comprises two opposite lateral faces which are bounded by a base, a top and a first and a second edge. The method comprises:

    (a) arranging the first and second electrodes in the first and second gaps, the surface of the workpiece forming an annular space surface at the gaps,(b) applying a positive voltage to the blank and applying a negative voltage to the first and second electrodes,(c) moving the first and second electrode in the direction of the first and second lateral faces.Step (b) is preceded by passing electrolyte between the two electrodes over the top toward the base.
