The patent filed by EssilorLuxottica SA describes a system for edging ophthalmic lenses that involves utilizing a first database table containing data related to eyewear frames, a second database table with correction data for the first data, and a processing unit to calculate an edging setpoint based on the first data corrected by the second data. This edging setpoint is then used by an edging machine to shape the ophthalmic lens along a final outline. The system also includes various corrective parameters in the second data to be applied to corresponding first data, ensuring accurate edging of lenses.
Additionally, the system includes a centering and blocking machine to position the lens according to the edging setpoint, or an edging machine with tools to machine the lens edge along the final outline. The first and second database tables are distinct, with the first table containing invariant data associated with different types of eyewear frames. The second data in the system includes corrective parameters that can be location-dependent or determined by an optician. Furthermore, the method for edging lenses involves selecting an eyewear frame, calculating a setpoint based on the first data corrected by the second data, and edging the lens accordingly. The method also includes steps for mounting the lens into the frame and recording feedback data in the second database table based on the accuracy of the mounting process.
