Abstract
To determine the position of rotationally drivable tools in machine tools, the moment of separation of the tool to be measured and a measuring beam, for example a laser beam of a light barrier, is used. The tool to be measured is first positioned in such a manner that the measuring beam is interrupted, and is then moved to a measuring position in which the moment of separation of the tool and the measuring beam occurs, and the measuring beam is no longer interrupted by the tool during at least one complete revolution. The moment of separation is used to determine the position of the tool.
Claims10
Method for determining the position of a rotationally drivable tool, having the following steps:
- positioning a rotationally drivable tool (14) in the beam path of a measuring beam (18),
- rotating the tool (14),
- choosing a movement direction,
- moving the tool (14) in the chosen direction, away from the measuring beam (18), to a measuring position in which the tool (14) is separated from the measuring beam (18),
- detecting the measuring position for a position of the tool (14) in which the measuring beam (18) is not interrupted during at least one revolution of the tool (14), and
- determining the position of the tool (14) from the measuring position.
