Abstract
An electrode for an electrochemical machining process is provided. The electrode comprises a curved, electrically conductive member, and an insulating coating covering at least a portion of a side surface of the curved, electrically conductive member. An electrochemical machining assembly is also provided for machining curved holes in a workpiece. The assembly includes at least one curved electrode and a power supply operatively connected to provide a pulsed voltage to the at least one curved electrode and to the workpiece. The assembly further includes a rotational driver operatively connected to move the at least one curved electrode along a curved path within the workpiece. The assembly is configured to remove material from the workpiece upon application of the pulsed voltage to the at least one curved electrode and to the workpiece. An electrochemical machining method is also provided for forming one or more curved holes in an electrically conductive workpiece.
