摘要：In an apparatus for performing work operations on a surface of one or morelenses, a frame and a mounting bracket adapted to releasably support at least one lensblank are provided. At least three pairs of articulated supports are also included with afirst end of each of the supports being bendably coupled at a first end to a mountingbracket adjacent to the other articulated support in the pair. The articulated supportsare each coupled at a second end to a point on the frame with the supports in each of thepairs diverging away from each other between the mounting block and the frame. A driveis associated with each of the articulated supports and moves each support, and therebythe mounting, individually between a raised and a lowered position in response tocommands issued from a controller having data corresponding to a particular lensprescription stored therein. A machining surface is also provided and during operation, asthe mounting bracket moves in response to the action of the articulated supports, thelens is engaged with and moves over the machining surface thereby performing a work
operation on the lens.
