ABSTRACT:
A gear shaper or shaver cutter which has broken or damaged teeth is salvaged by removing good teeth from an identical cutter which is otherwise unsalvagable. The removal of damaged teeth from the salvagable cutter, and removal of good teeth from the unsalvagable cutter, is done by electrical discharge machining (EDM) wire. The good teeth are removed as an integral group which is snugly fitted into and plugs the slot where the damaged teeth were removed from the salvageable cutter. The group is locked in place by a lock pin in an aperture made by EDM electrode procedure, the lock pin being welded in place by electron beam welding, and or any other suitable state of the art.
