Abstract:
An eyeglass lens processing apparatus for processing a periphery of an eyeglass lens, comprising:a detecting unit, which detects an edge position of the lens based on inputted target lens shape data and layout data; a processing unit, which has at least one grinding tool and which processes the lens periphery by relatively moving the lens with respect to the grinding tool, the at least one grinding tool being used in plural processing modes including at least two of: a plane finish processing mode in which the lens periphery is finished flatly; a bevel finish processing mode in which the lens periphery is finished with a bevel formed to the lens periphery; a plane polish processing mode in which the lens periphery is finished and polished flatly; a bevel polish processing mode in which the lens periphery is finished and polished with a bevel formed to the lens periphery; and a groove processing mode in which the lens periphery is finished with a groove formed to the lens periphery; a first setting unit, which divides the lens periphery into plural ranges; a second setting unit, which sets different processing modes for the plural ranges, respectively; a computing unit, which obtains processing data for the respective ranges, different in processing mode, based on data on edge position and data on the set different processing modes corresponding respectively to the ranges; and a control unit, which generates a control signal to the processing unit based on the obtained processing data.
