Method for scanning the contours of openings in a spectacles frame and use of a device for scanning the contours of openings in a spectacles frame for the peripheral grinding of spectacles lenses
The method involves controlling the rotating speed of a tracing pin (24) relative to a spectacle frame opening (23) depending on the radial velocity or radial acceleration and the speed or acceleration by an evaluation and control unit (33) in direction of the Z-axis of the tracing pin. The radial velocity or radial acceleration and the speed or acceleration is remained within the predetermined limits in the direction of the Z-axis of the tracing pin. An independent claim is also included for an application of a device for scanning the contour of a spectacle frame opening.
