Abstract

An electrochemical machine is disclosed for use in an electrochemical machining process to simultaneously generate different levels of metal removal. The electrochemical machine comprises at least two electrodes, each including an electrically conductive cylinder having an external surface partially coated with an insulated coating. The insulating coating is in a pattern defining raised areas to be formed on an internal surface of a predrilled hole in a workpiece wherein at least one of the electrodes has a varied pattern of insulating coating.
