  • Patent number: 10421136
    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 C1, spatial shifting axes of a machine column Z1, X1, and Y1, and a V1-axis corresponding to the tool axis. The method further includes specifying a correction in the axial direction in one of the axes Z1, V1 and C1, and calculating the correction amount of further axes by the controller depending on the specified axis.

  • Publication number: 20190176253
    Abstract: The present disclosure shows a method for gear cutting a workpiece on a machine tool that comprises a workpiece holder drivable about an axis of rotation and at least one tool holder drivable about an axis of rotation, wherein for the gear cutting operation a tool with a circular cylindrical shell surface is used, which with its shell surface is guided along a tooth flank of the workpiece tangentially to the target contour to be produced. According to an embodiment of the present disclosure it is provided that the tangential alignment of the shell surface relative to the target contour to be produced is achieved by positioning the tool along a first linear axis and by a rotary position of the workpiece about its axis of rotation.

  • Patent number: 9440299
    Abstract: The invention relates to method of manufacturing a multiple of identical gears by means of cutting machining, in particular hob cutting or hob grinding, on a gear-cutting machine, wherein workpieces are machined by means of a rotating tool which is brought into engagement with the workpiece via the control of NC axes of the gear cutting machine. In accordance with the invention, deviations from workpiece to workpiece are compensated by a respective different control of at least one of the NC axes of the gear cutting machine.

  • Patent number: 8931336
    Abstract: The present disclosure relates to a method of measuring and inspecting a workpiece belonging to a gear pair, wherein the method is carried out on a gear cutting machine producing the workpiece, wherein a mating test piece mounted at the working head, in particular at the cutting head, is moved in the direction of the workpiece clamped in the workpiece mount of the machine table until the gear pair is in engagement and the corresponding working axial spacing is reached, the workpiece is driven via the drive movement of the mating test piece of the gear pair, the rotational position of the workpiece to be measured is recorded and the detected actual position is compared with a reference position and at least one value characterizing the rolling gear deviation of the workpiece is calculated while taking account of the comparison made.

  • Patent number: 8186032
    Abstract: Tool arrangement for the production of helical teeth in gear wheels, wherein a roughing hob (20), at least one deburring cutter (16, 18) and a finishing hob (12) can be fastened on a common mandrel (14) in a predetermined rotational position relative to one another, and the teeth of the finishing hob, which are situated along a helical line, each have a different cross section such that the engagement angle of the right or left flanks decreases continuously starting from a maximum value of the first tooth up to the last tooth, and the maximum engagement angle of the right flanks of the first or last tooth coincides with the minimum engagement angle of the left flanks, and vice versa.
