Abstract

A method is proposed for measuring tools on a machine tool with a measuring device, wherein by means of a movement of a spindle of the machine tool the measuring device is temporarily positioned at a measuring point on the machine tool in order to carry out one or more measurements, the measuring point differing from a spindle mount. Furthermore, a measuring apparatus is proposed which is embodied in such a way that the measuring device can be positioned at a measuring point on the machine tool for a measuring operation by means of a spindle movement of a machine tool, said measuring point differing from a spindle mount.

Claims

1. A method for measuring tools on a machine tool with a measuring device, comprising picking up the measuring device with a spindle of the machine tool, and moving the spindle of the machine tool to temporarily attach the measuring device at a measuring point on the machine tool in order to carry out one or more measurements, wherein the measuring point differs from a spindle mount.

2. The method as claimed in claim 1, wherein the measuring device is removed from the measuring point on the machine tool after the measurement or measurements has/have been concluded.

3. The method as claimed in claim 2, wherein before the removal of the measuring device from the measuring point the measuring device is connected to a standardization normal.

4. The method as claimed in claim 1, wherein the measuring device is moved from the measuring point to a parking station after a measurement is terminated.

5. The method as claimed in claim 1, wherein the measuring device is mounted together with a standardization normal for positioning at the measuring point.

6. The method as claimed in claim 5, wherein the measuring device is removed from the standardization normal after the measuring device has been positioned at the measuring point.

7. The method as claimed in claim 5, wherein after standardization the standardization normal is moved into a parking position.

8. The method as claimed in claim 1, wherein the measuring device is standardized after the positioning of the measuring device at the measuring point.

9. A measuring apparatus having a measuring device for measuring tools, wherein the measuring device is picked up by a spindle of a machine tool, and the spindle of the machine tool moves to temporarily attach the measuring device at a measuring point on the machine tool for carrying out a measuring operation, wherein said measuring point differs from a spindle mount.

10. The measuring apparatus as claimed in claim 9, wherein the measuring device comprises a contact-forming measuring device.

11. The measuring apparatus as claimed in claim 9, wherein the measuring device comprises a contactless measuring device.

12. The measuring apparatus as claimed in claim 9, wherein a standardization normal is provided which is connected to the measuring device in a releasable connection.

13. The measuring apparatus as claimed in claim 12, wherein the measuring device can be disconnected from the standardization normal, in particular after the measuring device has been positioned at the measuring point on the machine tool.

14. The measuring apparatus as claimed in claim 12, wherein the measuring device is activated by disconnection from the standardization normal.

15. The measuring apparatus as claimed in claim 9, wherein, for a positioning process on the machine tool, the measuring device is arranged at least partially in a standardization normal.

16. The measuring apparatus as claimed in claim 15, wherein the standardization normal is hollow and cylindrical.

17. The measuring apparatus as claimed in claim 9, wherein the measuring device has an adaptor device for attachment to a machine tool.

18. The measuring apparatus as claimed in claim 9, wherein the measuring device has a standing surface for placing it on a tool table of a machine tool.

19. The measuring apparatus as claimed in claim 9, wherein the apparatus is configured for accommodation in a conventional tool magazine.

20. The measuring apparatus as claimed in claim 9, wherein the apparatus has a tool mount for a tool spindle.

21. The measuring apparatus as claimed in claim 9, wherein the measuring device is activated by positioning on the machine tool.

22. The measuring apparatus as claimed in claim 9, wherein the measuring device can be placed in an active state by sensing with a standardization normal.

23. The measuring apparatus as claimed in claim 9, wherein the measuring device can be activated and/or deactivated by means of infrared signals or radio signals.
