The invention relates to a method for machining a toothing of a workpiece held in a clamping, in which method a toothing tool that rotates about its rotational axis and comprises cutting edges is brought into in particular rolling chip-removing machining engagement with the toothing that in particular rotates about its rotational axis, in order to produce a predetermined tooth flank end geometry in one or more machining passes, wherein during the machining pass which produces the tooth flank end geometry, monitoring responsive to the event of a removed chip being pressed into a machined tooth flank of the toothing by means of the in particular rolling machining process is carried out and, if the monitoring responds, an additional toothing machining process that removes the material protrusion on top of the tooth flank end geometry formed by the chip that was pressed in during the event which occurred is implemented in particular automatically, which process is carried out in particular in the same clamping of the workpiece and in particular by means of the toothing tool itself.

A process for improving the excitation behavior of a ground bevel gear set by altering the surface structure of a gear set member from tooth slot to tooth slot (Teeth 1-3). The method comprises shifting the roll-positions in a way that not every facet or flat (F) is positioned the same way on each flank (2) and/or changing the distances of the roll angle along a tooth slot (delta RPj) whereby flats are spaced unequally (i.e. varying widths) along the tooth. One or more additional processes for altering the surface structure may be included.

A method for the grinding finish machining of an already toothed gearwheel workpiece in an NC-controlled machine tool, comprising the following steps: a. providing the gearwheel workpiece in the machine tool, b. providing a first grinding tool in the machine tool, c. providing a second grinding tool in the machine tool, d. grinding machining of at least one tooth flank of the gearwheel workpiece using the first grinding tool, e. grinding machining of at least one tooth flank in the transition region to the tooth head of the gearwheel workpiece using the second grinding tool in the machine tool to generate a head edge rounding on the gearwheel workpiece, f. further grinding machining of at least one tooth flank of the gearwheel workpiece using the first grinding tool and/or the second grinding tool in the machine tool.

A bevel gear set and a method of manufacturing the same are provided. The bevel gear set may include a first bevel gear and a second bevel gear. The first and second bevel gears may be spiral bevel gears or hypoid spiral bevel gears. The first and second bevel gears may each have a gear tooth surface having a plurality of teeth formed thereon, such that the teeth of the first bevel gear and the teeth of the second bevel gear are configured to engage in a meshing engagement. The teeth are machined onto the respective gear tooth surface via a face milling process. Each tooth includes a tooth top, a plurality of meshing surfaces, and at least one chamfer. The chamfer may be formed at an abutment edge disposed between the tooth top and a respective meshing surface via a brushing process directly following the machining of the teeth.

A cutting tip, a cutting tool and a gear edge cut-off device have greater ease-of-use than the conventional art. The cutting tip has a shaft portion supported linearly movably and forwardly biased in a linearly moving direction, an angular base portion provided at a front end of the shaft portion and having a pair of skirt faces and a ridge portion that extends obliquely with respect to the linearly moving direction, a groove depressed near the ridge portion of the skirt face, a blade edge on the cutting blade, positioned on a border line between the ridge portion and the groove, a rake face provided on the cutting blade and positioned further toward the groove side than the blade edge, and a flank face positioned further toward the ridge portion side than the blade edge and jutting out in the forward direction as it retracts from the blade edge.

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.
