PROCEDE D'USINAGE POUR TOURNAGE D'UNE FACE D'UN VERRE DE LUNETTES |
摘要 |
A machining method for machining a surface of a spectacle lens at a fixed rotation speed, includes a step of determining the rotation speed from geometric characteristics of the surface, characterized in that the step of determining the rotation speed includes the following steps: a value (Maxdiff) representative of the largest difference in geometric value of the mean sphere on the surface is determined; and the rotation speed is deduced from the value (Maxdiff) of the largest difference in geometric values of the mean sphere on the surface and from a geometric value of the cylinder (FV torus) at a predetermined far-vision control point. |
