EYEGLASS LENS PROCESSING APPARATUS AND EYEGLASS LENS PROCESSING PROGRAM
First Claim
1. An eyeglass lens processing apparatus comprising:
- a first rotational shaft which is configured to hold and rotate an eyeglass lens;
a finishing tool which is configured to perform finishing on a rim of the eyeglass lens to have a target shape of the eyeglass lens;
a chamfering tool which is configured to perform chamfering on an angular portion of an edge of the eyeglass lens which is finished by the finishing tool;
a second rotational shaft, to which the chamfering tool is attached;
an adjustment unit which is configured to adjust a relative positional relationship between the first rotational shaft and the second rotational shaft;
a control portion which is configured to control driving of the adjustment unit;
a chamfering angle setting portion which is configured to set a chamfering angle which is an angle formed between a rotational center axis of the first rotational shaft and a processing tool surface of the chamfering tool when performing the chamfering;
an edge information acquisition portion which is configured to acquire information regarding an edge surface shape of the eyeglass lens; and
an angle correction portion which is configured to correct the chamfering angle which is set by the chamfering angle setting portion, based on the information regarding the edge surface shape which is acquired by the edge information acquisition portion,wherein the control portion is configured to control the driving of the adjustment unit and adjust the relative positional relationship between the first rotational shaft and the second rotational shaft to perform the chamfering, based on the chamfering angle which is corrected by the angle correction portion.

12. A non-transitory storage medium having an eyeglass lens processing program stored thereon and readable by a processor of an eyeglass lens processing apparatus, the eyeglass lens processing program, when executed by the processor, causing the eyeglass lens processing apparatus to:
-
when performing chamfering on an angular portion of an edge of an eyeglass lens which is finished by a finishing tool, set a chamfering angle which is an angle formed between a rotational center axis of a first rotational shaft which is configured to hold and rotate the eyeglass lens and a processing tool surface of a chamfering tool which is configured to perform chamfering on the angular portion of the edge of the eyeglass lens; acquire information regarding an edge surface shape of the eyeglass lens with respect to the first rotational shaft; correct the chamfering angle based on the information regarding the edge surface shape which is acquired by the acquiring step; and control driving of an adjustment unit which is configured to adjust a relative positional relationship between the first rotational shaft and a second rotational shaft to which the chamfering tool is attached so as to adjust the relative positional relationship between the first rotational shaft and the second rotational shaft based on the chamfering angle which is corrected by the correcting step.
