Computerized Inspection of Gear Tooth Surfaces

Abstract

An approach is proposed that uses coordinate measurements of the real surface of spiral bevel gears to determine the actual machine tool settings applied during the gear manufacturing process. The deviations of the real surface from the theoretical one are also determined. Adjustments are then applied by machine tool corrections to minimize these surface deviations. This is accomplished by representing the real surface analytically in the same Gaussian coordinates as the theoretical surface.
