Abstract:
A method and device for edging an ophthalmic lens, includes turning the lens about a first axis of rotation and working on the edge face of the lens with a beveling grindwheel or cutter having a beveling groove or chamfer and mounted to rotate about a second axis of rotation. While machining the edge face of the lens with the beveling grindwheel or cutter, the first and second axis of rotation are moved dynamically relative to each other as a function of the angle of rotation of the lens about the first axis of rotation, in such a manner that during machining of each portion of the edge face of the lens, the tangent to the curve of the working portion of the beveling groove or chamfer is substantially parallel to the tangent to the curve of the bevel desired on the portion of the edge face.
