Apparatus for judging whether an uncut lens should be machined or not and lens grinding machine having the same
An apparatus for judging whether or not an uncut lens should be machined is provided. The apparatus judges whether or not a lens having a desired lens frame configuration can be obtained from an uncut lens before the lens is subjected to a grinding treatment by a lens grinding machine. The apparatus also judges whether or not an already sucked and attached uncut lens should be machined by judging whether a "machining interference" caused by a sucking disk sucked and attached to the uncut lens will come in contact with a grinding wheel, and/or whether or not a lens of a desired lens frame configuration can be obtained from the uncut lens before the uncut lens with the sucking disk already sucked and attached thereto is subjected to a grinding treatment. A lens grinding machine incorporating such a judging apparatus is also provided.
