A method for honing processing a toothed wheel in which the toothed wheel and a honing tool mesh with each other and the rotation axes of the toothed wheel and honing tool intersect at an axial intersection angle. The toothed wheel and honing tool carry out a relative movement which oscillates in an axial direction of the rotation axis of the toothed wheel and are positioned in a direction towards each other at the same time in a radial direction with respect to the rotation axis of the toothed wheel starting from an end position in order to remove material from the toothed wheel. During the oscillating relative movement which is directed in an axial direction of the rotation axis of the toothed wheel, the rotation position of the toothed wheel with respect to the rotation axis thereof is changed in accordance with the positioning in a radial direction.

A device, a method and a computer program product for machining a workpiece, in particular for cutting teeth into a workpiece, includes a base, a workpiece spindle mounted rotatably about a first axis (A) for receiving the workpiece, a first machining head having a first tool spindle mounted rotatably relative to a first tool axis for receiving a first machining tool, and a second machining head having a second tool spindle mounted rotatably relative to a second tool axis for receiving a second machining tool. At least the first machining head is provided with the first machining tool for power skiving the workpiece and at least the second machining head is variably positionable and/or variably orientable relative to the first machining head and independently of the first machining head.

To provide a gear machining device and a gear machining method which achieve machining of tooth flanks having different torsion angles with high degree of accuracy. In a gear machining device, a side surface of a tooth of a gear includes a first tooth flank and a second tooth flank having a different torsion angle from the first tooth flank, a cutting blade of a machining tool has a blade traces having a torsion angle determined based on a torsion angle of the second tooth flank and an intersection angle between a rotation axis of a workpiece and a rotation axis of the machining tool so as to allow the second tooth flank to be machined on the pre-machined first tooth flank.
