  • Lens edging machine and method
    Patent number: 4885875
    Abstract: A method of grinding the periphery of an opthalmic lens blank (B) comprising rotating the blank periphery against a grinding wheel (38, 40, 42) and simultaneously rotating a template (110) disposed coaxially relative to the blank and having the desired peripheral configuration of the finished lens. The template is positioned for cooperation with a follower (114) such that the template causes rotation of the follower when the template and follower are caused to engage one another in response to removal of material (MR) from the blank. Each period of time during which the follower is set into rotation by the template is determined and compared to a predetermined period corresponding to one revolution of the blank.
