ABSTRACT:
A method for the precision working of crowned tooth flanks of particularly hardened gears with a two-flank abutment and at crossed axes with an abrasive gear-shaped or rack-shaped tool, in which the tool carries out several back and forth feed movements relative to the workpiece in a direction X extending at an angle .epsilon. inclined with respect to the workpiece axis 4 and a plunge feed movement in the sense of a center-distance reduction. The tool does not have corrected teeth. The crowning is created only at the end of the precision working during at least one back and forth feed movement without a plunge feed movement.
