Method of manufacturing multiple identical gears using a gear cutting machine

摘要

The invention relates to method of manufacturing a multiple of identical gears by means of cutting machining, in particular hob cutting or hob grinding, on a gear-cutting machine, wherein workpieces are machined by means of a rotating tool which is brought into engagement with the workpiece via the control of NC axes of the gear cutting machine. In accordance with the invention, deviations from workpiece to workpiece are compensated by a respective different control of at least one of the NC axes of the gear cutting machine.

1. A method of manufacturing a multiple of identical gears by cutting machining, in particular gear cutting or gear hob grinding, on a gear cutting machine,
wherein workpieces are machined by a rotating tool which is brought into engagement with the workpiece via the control of NC axes of the gear cutting machine, wherein the tool is shifted for each workpiece during the machining of a plurality of workpieces by a determined distance along its axis of rotation to bring a different point of the tool into engagement with the each workpiece of the plurality of workpieces, wherein deviations from workpiece to workpiece due to the tool geometry and/or its influence on the cut gear geometry at the different point of the tool are compensated by a respective different control of at least one of the NC axes of the gear cutting machine; wherein deviations of the tool geometry in the shift direction and/or their influence on the cut gear geometry are determined, in particular with respect to the tooth thickness; and wherein the tool geometry and/or its influence on the cut gear geometry is determined at least at two sampling points which correspond to different shift positions of the tool, and advantageously the tool geometry and/or its influence on the cut gear geometry over the shift range of the tool is interpolated with reference to the at least two sampling points to control the NC axes of the gear cutting machine.
