Abstract
A method for deburring a gear blank includes correcting chamfer sizes, chamfer shapes and chamfer symmetry at tooth edges which were produced with a deburring cutter with a strongly asymmetric tooth shape (ChamferCut). The chamfers are semi-automatically corrected by coupling the movement of several axes of a gear cutting machine, including a workpiece axis of rotation C, spatial shifting axes of a machine column Z, X, and Y, and a V-axis corresponding to the tool axis. The method further includes specifying a correction in the axial direction in one of the axes Z, Vand C, and calculating the correction amount of further axes by the controller depending on the specified axis.
