Abstract

A process and an apparatus for generating control data, wherein a first tooth flank geometry is determined which corresponds to a geometry of a first tooth flank of the herringbone gearing, a second tooth flank geometry is determined which corresponds to a geometry of a second tooth flank of the herringbone gearing, a transition section geometry is determined which corresponds to a geometry of a transition section between the first tooth flank and the second tooth flank, an overall tooth flank geometry is determined which comprises the first tooth flank geometry, the transition section geometry and the second tooth flank geometry, and the control data is generated based on the overall tooth flank geometry and machining paths are indicated, each extending transversely to the profile direction of the tooth flanks and along the first tooth flank geometry, the transition section geometry and the second tooth flank geometry.
