Abstract
A process is set forth for electrochemically machining holes in a workpiece, such as a die, in such a manner so as to virtually eliminate surface finish patterns normally introduced by the electrochemical machining process, by randomly forming sequences of patterns of holes extending in rows across the workpiece along its extent, and then rotating the workpiece 180.degree. and randomly forming additional sequences of patterns of holes across the workpiece adjacent those sequences of holes which were formed prior to rotating the workpiece 180.degree..
