Abstract
A method of electrically machining a hole in a conductive work piece may include providing a tool having a conductive tool head in close proximity to the conductive work piece. A voltage may be applied across the tool head and the work piece to create an electric field in the hole at the tool head. The electric field may be asymmetric with respect to the centerline of the hole. The orientation of the hole may be altered by removing material from the work piece using the asymmetric electric field.
