MACHINING METHOD FOR MACHINING ONE FACE OF A SPECTACLE LENS

摘要

The invention relates to a machining method for machining a surface of a spectacle lens at a fixed rotation speed, comprising a step of determining said rotation speed from geometric characteristics of said surface, characterized in that the step of determining the rotation speed comprises the following steps: a value (Maxdiff) representative of the largest difference in geometric value of the mean sphere on said surface is determined; and the rotation speed is deduced from said value (Maxdiff) of the largest difference in geometric values of the mean sphere on said surface and from a geometric value of the cylinder (FV torus) at a predetermined far-vision control point.
