Abstract
Quick-change methods and apparatus enable the cutting tool of a lens cutting machine to be exchanged with minimal down time of the machine. A replacement cutting tool is gauged in an off-machine gauging mechanism while the machine is able to continue an on-going lens cutting operation. A stop surface of the replacement tool is adjusted in the gauging mechanism in order to reset the cutting edge, whereby subsequent insertion of the replacement tool in the machine assures that the cutting edge will be located in a predetermined reference plane of the machine.
