Method for machining a metal component

A method for machining a metallic structural component having a pre-contour with different over-measures in different areas relative to a predetermined end-contour, the method including the following steps:

• a) determining the over-measures of the pre-contour relative to the predetermined end-contour in the different areas of the structural component;
• b) simultaneously feeding at least one electrode for pulsed electrochemical ablation toward one side of the structural component in an area of a larger over-measure of the pre-contour relative to the end-contour and feeding at least another electrode for pulsed electrochemical ablation toward a bilaterally opposing side of the structural component in an area of a smaller over-measure of the pre-contour relative to the end-contour, wherein the feed velocity of the electrode in the area of the larger over-measure of the pre-contour is larger than the feed velocity of the electrode in the area of the smaller over-measure of the pre-contour;
• and
• c) simultaneously finishing the bilaterally opposing sides of the structural component using pulsed electrochemical ablation.

• c) oscillating each electrode, as the electrode is being fed toward the structural component, such that the electrode gap between the electrode and the structural component repeatedly ranges between a minimal spacing and a maximal spacing.
