EYEGLASS LENS PROCESSING APPARATUS FOR PROCESSING PERIPHERY OF EYEGLASS LENS AND EYELGASS LENS PROCESSING METHOD
First Claim
1. An eyeglass lens processing apparatus for processing a periphery of a lens, comprising:
- a lens edge position detecting unit which obtains edge positions at a front face and a rear face of the lens based on target lens shape data;
an edge corner processing tool which processes an edge corner of the lens rear face;
a correction data input unit which inputs correction data of the edge corner for avoiding interference between an edge of the lens rear face after finish processing and a nose pad arm of an eyeglass frame, the correction data including data on a position of interference between the edge and the nose pad arm, data for setting a processing amount at the interference position, and a processing range of the edge;
a processing data computing unit which determines a processing path of the edge corner of the lens rear face, based on data on the edge position and the correction data, to obtain processing data; and
a processing controller which processes the edge corner of the lens rear face by the edge corner processing tool in accordance with the processing data.
