ABSTRACT:
A computer-controlled lens generating arrangement (1) has a calibration gauge (14) mountable on a lens chuck (28) and moveable into a calibration position for detecting a worn or eroded condition of a tool (18). When a worn or eroded condition of tool (18) is detected, data are provided to a computer (60) which recomputes positioning data for the chuck (28), and repositioning of the chuck (28), as well as the angle of the cutting tool (18), takes place.
