Abstract

La invención se refiere a un método de mecanizado mediante torneado de una superficie de una lente para anteojos, a una velocidad de rotación fija, que comprende una etapa de determinar la velocidad de rotación a partir de las características geométricas de la superficie, caracterizado porque la etapa de determinar la velocidad de rotación comprende las etapas siguientes: determinar un valor (Maxdiff) representativo de la diferencia más grande de los valores geométricos de la esfera madia sobre la superficie, y deducir la velocidad de rotación del valor (Maxdiff) de la diferencia más grande de los valores geométricos de la esfera media sobre la superficie y de un valor geométrico del cilindro (Toro VL) en un punto predeterminado de control de la visión de lejos.
