The present invention relates to a method for determining a vibration amplitude of a tool 3, comprising the steps: generating a light beam 23 of a light barrier 2 with a transmitter 21 for generating the light beam 23 and a receiver 22 for detecting a light intensity of the light beam 23; generating a receiver signal on the basis of a light intensity, detected by the receiver 22 of the light barrier 2, of the light beam 23; positioning a tooltip 31 of the tool 3 in the light beam 23; causing the tool 3 to vibrate ; determining the vibration amplitude of the tool 3 from a modulation of the receiver signal brought about by the vibration of the tool 3. |
