Abstract
A machining process for forming a raised area in a wall of a predrilled hole includes distributing electrolyte via a workpiece internal cavity to a number of predrilled holes. Next, position a template including at least one electrode coated with an insulating material in a pattern defining the raised area to be formed in the wall of the predrilled hole below the workpiece such that the electrode is positioned within a predrilled hole and machining by passing electric current between the electrode and the workpiece wall and circulating electrolyte through the hole.
