ABSTRACT:
In an apparatus for performing work operations on a surface of one or more lenses, a frame and a mounting bracket adapted to releasably support at least one lens blank are provided. At least three pairs of articulated supports are also included with a first end of each of the supports being bendably coupled at a first end to a mounting bracket adjacent to the other articulated support in the pair. The articulated supports are each coupled at a second end to a point on the frame with the supports in each of the pairs diverging away from each other between the mounting block and the frame. A drive is associated with each of the articulated supports and moves each support, and thereby the mounting, individually between a raised and a lowered position in response to commands issued from a controller having data corresponding to a particular lens prescription stored therein. A machining surface is also provided and during operation, as the mounting bracket moves in response to the action of the articulated supports, the lens is engaged with and moves over the machining surface thereby performing a work operation on the lens.
