Abstract
In the continuous generation grinding of a gear the modifications of tooth trace contours and/or corrections of tooth trace deviations determined by flank measurement are specified separately for the left and right flanks (3, 4) of the gear (1). By means of these data, supplementary motions of the NC machine axes across the face width of the left flank (3) and the right flank (4) of the gear (1) are calculated in a control system of a gear flank grinding machine, by means of which a grinding worm produces the specified modified or deviation corrected tooth traces on the left flanks (3) and the right flanks (4) of the gear (1) in one and the same grinding stroke.

Process for the modification of tooth traces and/or the correction of tooth trace deviations of a gear (1) in the continuous tooth flank generation grinding of the gear (1), by which the modifications and/or the corrections take place by means of influencing the machine kinematics of a gear flank grinding machine, in which,
- independent of each other, a modification and/or a correction of tooth trace deviations of the left flank (3) and the right flank (4) of the gear (1) are specified, that from these specified modifications and/or corrections supplementary motions of NC axes of the tooth flank grinding machine are calculated as function of the grinding stroke position (z), and that by superimposition of these supplementary motions on a relative motion between the grinding worm of the gear flank grinding machine and gear (1) tooth traces with specified modifications and/or corrections are produced on the left and the right flanks (3, 4) of the gear (1) in one and the same grinding stroke.
