Method for producing a gear wheel having a herringbone gearing and method and device for generating control data for forming a herringbone gearing on a workpiece

摘要

Process for producing a toothed wheel (10) having a herringbone by toothed spindle machining by milling of a workpiece on a machine tool numerical control, which comprendeal least four axes, in particular in a milling machine, a machine a universal tool or spindle machining center, by successively output machining paths over the workpiece with unaherramienta milling, in particular an end mill, the machine tool based on control data, comprising; - generating control data for directing the milling tool relative to the workpiece, quecomprende: - establishing a first geometry (12a, 12b) tooth flank, which corresponds to a geometry unprimer tooth flank of a first toothed part of the herringbone gearing, - establishing a second geometry (13a, 13b) tooth flank, which corresponds to a geometry ofa second tooth flank of a partial second toothing of the herringbone gearing, - establish a geometry (14a, 14b) transition section, corresponding to a geometry unasección transition between the first tooth flank and the second tooth flank - determining a geometry (12a, 13a, 14a; 12b, 13b, 14b) of overall tooth flank which comprises laprimera geometry (12a, 12b) tooth flank geometry (14a, 14b) and transition section lasegunda geometry (13a, 13b) tooth flank, and - generating control data based on the geometry a (12a, 13a, 14a; 12b, 13b, 14b) flank dienteglobal indicating data control data pathway to direct the milling tool of the machine tool along machining paths, running the machining paths in each entransversal case the profile direction of the tooth flanks, in particular different profile heights, I lolargo of the first geometry (12a, 12b) tooth flank geometry (14a, 14b) of detransición section and the second geometry (13b) tooth flank; and - machining by milling of the workpiece on the machine tool with the tool in fresarbasándose generated control data, controlling the milling tool successively lolargo of machining paths indicated by the data track.
