Patent ID: 7322082

Claim:
An eyeglass lens processing apparatus for processing a periphery of an eyeglass lens, the apparatus comprising: a lens chuck shaft that holds and rotates the lens; an end mill that processes the periphery of the lens; an end mill tilting unit that varies a tilt of the end mill with respect to the lens chuck shaft; an end mill moving unit that relatively moves the end mill with respect to the lens held by the lens chuck shaft; a target lens shape input unit that inputs an target lens shape; a lens measuring unit that detects a position of a processing edge of the lens based on the input target lens shape; and a control unit that controls the end mill tilting unit and the end mill moving unit to perform a roughing process on the lens using the end mill while locating the end mill to be parallel to the chuck shaft based on the input target lens shape and to perform a beveling process on the roughing-processed lens using the end mill while tilting the end mill with respect to the chuck shaft based on the detected position of the processing edge and an input or stored beveling shape.
