    Abstract: An apparatus (1) for heat treating the surfaces (32b) of gear teeth (32a) via magnetic inductive heating comprises a magnet assembly (40) and a workpiece (or gear) holder (30) operatively mounted on a base (12). The magnet assembly (40) is rotatable in a first plane about a first axis (A1), and the work-piece holder (30) (on which a gear (32) can be removably mounted) is rotatable about a second axis (A2) in a second plane. The first and second axes (A1, A2) are spaced apart from each other and the first and second planes intersect each other. The apparatus (10) includes a mechanism (16, 22) to move one (or both) of the magnet assembly (40) and the workpiece holder (30) relative to each other, such that the magnet assembly (40) and work piece holder (30) can be moved between a position in which the magnet assembly (40) and the gear (32) mounted on the work-piece holder (30) are in heating proximity to each other and a second position in which the magnet assembly (40) and gear (32) are out of heating proximity with each other.

    Abstract: A face-gear forging die is constructed from a blank, and is cut to specification using a wire electrical discharge machining (EDM) process. The wire electrical discharge machining process is computer controlled, according to pre-specified instructions. The wire electric discharge machining process can also be used to cut the face gear tooth (47) directly, to thereby circumvent the forging procedure. The complex, curved surfaces of the face gear teeth (47) are mathematically approximated with a ruled surface, and the mathematical approximation is input to the wire electric discharge machining apparatus for subsequent execution and forming of the die.
