The disclosed system includes a personal computer (10) having correction coefficients (±) for the correction of errors in the tooth profile and correction coefficients (²) for the correction of meshing positions, the correction coefficients being provided for each number of times the shaving cutter has been sharpened and for each shaving-cutter feature. The target tooth-profile data (Do), the tooth-profile error data (”D) which is the difference between the target tooth-profile data (Do) and the measured tooth-profile data (Dm), and the correction coefficients (± and ²) acquired in correspondence with the number of times sharpened and the cutter features are applied to the equation Dcc=Do+±”D+², to fnd the aimed tooth-profile data (Dcc). Then, the shaving-cutter tooth-profile data (ds) is found from the aimed tooth-profile data (Dcc). Thus, the shaving cutter can be sharpened appropriately, even when the outer diameter and the tooth thickness of the shaving cutter are reduced as a result of sharpening the shaving cutter. |
