Claim Text:
1. A method for cutting teeth into a workpiece wheel by hob peeling, comprising the steps of: rotating a workpiece spindle that holds the workpiece wheel into which the teeth are to be cut, wherein along the root circle of the workpiece wheel, a spacewidth extends between each tooth to be cut, rotating a tool spindle that carries a peeling wheel in a fixed speed ratio to the workpiece spindle; crossing an axis of rotation of the workpiece wheel at an angle to an axis of rotation of the tool spindle; and advancing the peeling wheel, which comprises cutting teeth with a regular tooth pitch by which tooth spacing of the teeth of the workpiece wheel is determined, in a direction of the axis of rotation of the workpiece wheel by relative movement between the tool spindle and the workpiece spindle, wherein each cutting tooth of the peeling wheel is separated from an adjacent cutting tooth of the peeling wheel by a distance equal to at least twice the tooth spacing of the teeth of the workpiece wheel, the cutting teeth having cutting edges that extend along a contour line of the cutting teeth in a plane of a broad side of the teeth, wherein the spacewidths of the workpiece wheel include plural groups of plural adjacent spacewidths, a cutting tooth being present only in one spacewidth out of each group of plural adjacent spacewidths during a full given revolution of the peeling wheel.
