Process for machining a gear workpiece, and corresponding pair of gears

A method comprising:

• fine machining with a multiaxis gear cutting machine a gear wheel workpiece comprising multiple tooth flanks and multiple tooth gaps, each tooth gap defined by a respective left flank and a respective right flank of said tooth flanks, wherein said fine machining includes performing a non-periodically distributed modification of flank topography of at least a subset of said tooth flanks using a gear cutting tool, wherein the at least a subset of said tooth flanks comprises a plurality of left flanks or a plurality of right flanks, the method further including
• assigning an individual different target topography to each tooth flank of the at least a subset of said tooth flanks, wherein, after performing the non-periodically distributed modification of the flank topography, each tooth flank of the at least a subset of said tooth flanks defines a different topography than all other tooth flanks of the at least a subset of said tooth flanks,
• measuring actual topography of each of at least a plurality of tooth flanks of the at least a subset of said tooth flanks after said fine machining,
• comparing, using a computer, for said each of said at least a plurality of tooth flanks, the actual topography thereof to the respective individual different target topography thereof and, in turn, determining any deviations between the actual topography and the respective individual target topography, and
• when one or more deviations exist, one or more of:
• performing a correction machining process on at least a portion of the respective tooth flank, or
• when said gear wheel workpiece is of a series of gear wheel workpieces fine machined in the gear cutting machine, performing said correction machining process on respective tooth flanks of at least one other gear wheel workpiece in the series.
