The method is used for machining flanks of unhardened or hardened, spur-toothed or helical-toothed, internally toothed or externally toothed cylindrical gears by skiving. Basic rotation is produced between a tool and a workpiece. In addition, a helical motion between the tool and the workpiece is produced. The relative motion between the tool and the workpiece is executed with high accuracy, and any variations in the relative motion are corrected. The tooth number z0 of the tool, for minimizing the effect of the variations of the tool and its mounting, is fixed in such a way that, in the case of z0>/=z2 (z2 is the tooth number of the workpiece, z0 is the tooth number of the skiving tool), the ratio i=z0/z2, and in the case of z0>z2, the reciprocal of the ratio 1/i=z2/z0, result in an integral value or the ratio of two integral numbers, the amount of which is as small as possible. |
