A process and an apparatus for generating control data, wherein a first tooth flank geometry 12b is determined which corresponds to a geometry of a first tooth flank of the herringbone gearing, a second tooth flank geometry 13b is determined which corresponds to a geometry of a second tooth flank of the herringbone gearing, a transition section geometry 14b is determined which corresponds to a geometry of a transition section between the first tooth flank and the second tooth flank, an overall tooth flank geometry 12b, 13b, and 14b is determined which comprises the first tooth flank geometry 12b, the transition section geometry 14b and the second tooth flank geometry 13b, and the control data is generated based on the overall tooth flank geometry 12b, 13b, and 14b and machining paths are indicated, each extending transversely to the profile direction of the tooth flanks and along the first tooth flank geometry 12b, the transition section geometry 14b and the second tooth flank geometry 13b.

Description

technical field [0001] The invention relates to a method for producing gears with herringbone teeth, on a numerically controlled machine tool comprising at least four axes, by continuously moving the milling tool of the machine tool along a machining path relative to the workpiece on the basis of control data to mill the workpiece A gear with herringbone teeth can be generated by means of a method. Specifically, the milling cutter can be an end mill, and the CNC machine tool can be a milling machine, a general-purpose machine tool or a machining center. The method comprises: on the basis of the profile of a tooth, generating control data, the control data comprising path data, the control data being usable for guiding the milling cutter of the machine tool along the machining path, and for using the The milling tool mills the workpiece on the machine tool, wherein the milling tool can be continuously guided along a machining path represented by the path data.

AI Technical Summary

Problems solved by technology

However, this method is also more costly and requires longer machining times due to the fact that the tooth flanks are machined separately, followed by machining the grooves with a smaller milling cutter, resulting in less cutting volume

In addition, since there is no rolling area available at the central end of the chevron teeth, the load on the border area of ​​the tooth flanks 12a, 12b, 13a and 13b close to the groove 11' increases
