TOOTH-PROFILE MANAGEMENT SYSTEM FOR SHAVING-CUTTER GRINDING MACHINE

WIPO Patent Application WO/2011/089761

A1

The disclosed system includes a personal computer (10) having correction coefficients (α) for the correction of errors in the tooth profile and correction coefficients (β) 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 (ΔD) which is the difference between the target tooth-profile data (Do) and the measured tooth-profile data (Dm), and the correction coefficients (α and β) acquired in correspondence with the number of times sharpened and the cutter features are applied to the equation Dcc=Do+α·ΔD+β, to find 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.
