Abstract
A method for producing a toothing on an in particular round workpiece, wherein the teeth are produced by a shaping method using a tool which moves along a path which is controlled by a lifting cam and in the case of which an exchange movement that runs substantially in the radial direction of the workpiece follows a downward movement which runs in the axial direction of the workpiece and serves to produce the tooth flanks, wherein the exchange movement is superimposed with a downward movement such that a curved path is produced during the exchange, is characterized in that the relative rake angle γrel of the tool (200) does not fall below a minimum rake angle γmin which corresponds to the rake angle γ of the tool (200), the rake angle γ being reduced by the angle δ between the longitudinal axis of the workpiece and the direction vector of the tool movement.
