Abstract
An electrode for an electrochemical machining process is provided. The electrode includes an electrically conductive member defining at least one passage and an insulating coating partially covering a side surface of the electrically conductive member. The insulating coating does not cover at least one of first and second exposed sections of the electrically conductive member, where the first and second exposed sections are separated by approximately 180 degrees and extend substantially along a longitudinal axis of the electrically conductive member. The insulating coating also does not cover an exposed front end of the electrically conductive member. An electrochemical machining method is also provided, for forming a non-circular hole in a workpiece using the electrode.
