ABSTRACT:
A method of grinding the peripheries of articles such as ophthalmic lenses and the like with a grinding wheel to a predetermined outline or edge configuration, is characterized by the steps of detecting the height of discrete positions on the grinding wheel surface between opposite sides thereof and generating signals having values representative of the height of the positions. The values of the signals are compared, and an indication is generated of the position on the grinding surface whereat the signals represent greatest height. The indication is then used to control movement of the article against the highest position on the grinding surface for being ground. In consequence, the wheel wears evenly, it retains a substantially cylindrical shape, all portions of its grinding surface are effectively used in grinding articles, and formation of a groove in its surface is prevented, whereby the wheel does not require retruing or reshaping and its useful life is significantly increased.
