Abstract
In a method for the machining of a workpiece () 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. According to the method, the feed movement component parallel to the workpiece axis and the cutting movement component parallel to the workpiece axis are oriented in opposite directions relative to each other.
