Eyeglass lens processing apparatus
First Claim
1. 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;
a memory that stores a beveling shape including a beveling tilt angle on a front surface side of the lens and a beveling tilt angle on a rear surface side of the lens; 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 based on the input target lens shape and to perform a beveling process on the roughing-processed lens using the end mill based on the detected position of the processing edge and the stored beveling shape.

Abstract
An eyeglass lens processing apparatus for processing a periphery of an eyeglass lens, the apparatus includes: 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; a memory that stores a beveling shape including a beveling tilt angle on a front surface side of the lens and a beveling tilt angle on a rear surface side of the lens; 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 based on the input target lens shape and to perform a beveling process on the roughing-processed lens using the end mill based on the detected position of the processing edge and the stored beveling shape.
