A gear machining support device supports machining when a tooth of a gear is machined on a workpiece by relatively moving the workpiece and a machining tool while synchronizing rotations of the workpiece and the machining tool around respective center axis lines thereof. The gear machining support device includes: a target modification amount storage unit configured to store target modification amounts of at least two of modification elements of a tooth surface shape of the tooth of the gear, the modification elements including crowning, bias, a helix angle, a pressure angle, and a tooth profile roundness; and a correction amount determination unit configured to determine a correction amount of a machining control element during a machining operation such that the at least two of modification elements approximate the respective target modification amounts stored in the target modification amount storage unit.

A method includes the following method steps: grinding of bevel gears, wherein the respective bevel gears have a straight toothing to be ground, wherein the grinding is carried out by a disk-shaped grinding tool by discontinuous generating grinding using a predetermined rolling ratio. A cutting face of the grinding tool, which rolls during the grinding with teeth of the straight toothing of a respective bevel gear, forms a section of a hollow cone inner surface, and wherein a respective longitudinal crowning is generated on the respective straight toothing of the respective bevel gears by the grinding using the cutting face forming the section of the hollow cone inner surface. The method is distinguished in that the grinding tool is a dressable grinding tool and dressing of the grinding tool is carried out.

The invention relates to a method for the fine-processing of a toothing by a single-indexing method, wherein a disk-type fine-toothing machine (S) that rotates about its axis is brought into rolling processing engagement with a tooth flank of the toothing in order to remove material from the tooth flank, wherein a line contact is established while in processing engagement, and the contact line moves over the tooth flank in accordance with a movement having a directional component (Xc0) that is radial to the toothing axis (C), and wherein the processing engagement is maintained in the same pitch with a reduced tangential distance between the tooth flank and the disk plane of the fine-processing tool and with a sign reversal of the radial directional component of the contact line displacement.
