  • Patent number: 9415454
    Abstract: In a method for the machining of a workpiece (2) which is driven in rotary movement about a workpiece axis (Z) and whose shape includes a periodic structure, specifically a workpiece with gear teeth, a cutting tool which has gear-like teeth with a cutting edge formed at a frontal end of the teeth and which is driven in rotary movement about a cutting tool axis that is radially spaced apart from the workpiece axis, is brought into a rolling engagement with the workpiece under a crossing angle between the two rotary axes, wherein the cutting edge removes material from the workpiece through a cutting movement that has a component in the direction parallel to the workpiece axis, and wherein for the machining of the workpiece over a desired axial range the cutting tool is in addition made to perform a feed movement having a component parallel to the workpiece axis.
