ABSTRACT:
An induction-hardening machine for the contour hardening of machine components such as gears includes a machine with both high-frequency and low-frequency induction generators operably arranged with corresponding induction coils positioned at a machine workstation and interfacing with computer controls. The high-frequency and low-frequency coils are arranged in a substantially concentric fashion such that the part to be induction hardened may be moved axially from one induction coil to the other depending upon the selected induction hardening process. The computer controls include a microprocessor operable to receive a computer disk which is formatted with specific machine settings and parameters for the automatic running and induction hardening of the particular part. The induction coils and the machine settings on the computer disk are all generated from a computer algorithm consisting of a series of equations and formulae which treat specific part characteristics and parameters so as to define the optimum coils and settings for induction hardening of that particular part.
