(under subclass 20) Device including a cutter adapted to be reciprocated to and fro across the work, which cutter is also intended to rotate between passes, for generating a tooth structure generally considered to be a gear.
(1) Note. The cutting action utilized in gear generating is that of a cutter which makes several passes through a workpiece or group of cutters, each of which makes at least one pass through the workpiece, the cutting action of each pass being such that the cumulative total of all the passes cuts out a portion of a gear tooth.
