Beschreibung
Zusammenfassung:	Methods of determining movement data representing the movement of a machining tool of an optical lens lathing device for machining one or more optical surfaces or parts thereof of a set of optical surfaces are described. The methods comprise a greatest radial slope amplitude determining step during which the greatest radial slope amplitude of the optical surfaces of the set of optical surfaces is determined. The methods also comprise a machining tool selecting step during which a machining tool having a window angle greater than or equal to the greatest radial slope amplitude of the optical surfaces of the set of surfaces to be manufactured is selected. The methods further comprise a movement data determining step during which movement data representing the movement of the selected machining tool are determined and synchronized with the angular position of the optical surface driven in rotation.
