Abstract
An electrochemical grinding wheel of substantially uniform conductivity along its contoured grinding surfaces is modified to reduce the conductivity at locations generally parallel to the tool-feed direction (perpendicular to the machine surface) so that electrochemical removal of material from the workpiece occurs substantially only at those surfaces which are transverse to the tool-feed direction. This prevents overcutting of the workpiece.
