Precision electrochemical machine for gear manufacture

A method of manufacturing a gear, the method comprising:

• coarsely machining a solid workpiece to roughly form a gear configuration in the workpiece;
• precision machining the workpiece to refine the gear configuration to a final dimension, wherein the coarsely machining and the precision machining processes comprise:
• applying a first charge to the workpiece and applying a second, opposite charge to an electrochemical machining (ECM) attachment, the ECM attachment having a pattern;
• and
• simultaneously forming a plurality of surfaces of a plurality of gear teeth in the workpiece using the pattern of the ECM attachment while applying the first charge to the workpiece and applying the second charge to the ECM attachment and turning the workpiece and the ECM attachment in opposite rotational directions such that the gear configuration comprising the plurality of gear teeth is formed in the workpiece, the plurality of surfaces of the plurality of gear teeth including at least one end face and a top land, wherein during the coarsely machining and the precision machining processes, the ECM attachment does not directly contact the workpiece.
