Abstract

An articulated arm CMM system comprises an articulated arm comprising a plurality of articulated arm members, a measuring probe at a distal end, and a base at a proximal end, the base comprising a docking portion. The articulated arm CMM system also includes a plurality of feature packs configured to electronically connect to the articulated arm via the docking portions and provide additional electronic functionality.

Claims

1. A coordinate measuring device configured to measure and output one or more geometric positions on an object by at least one of contacting a point on the object or positioning the coordinate measuring device so as to view a point on the object, the coordinate measuring device comprising:

a single docking portion configured to form a connection with a modular feature pack that can provide at least two additional and distinct features or functionalities to the coordinate measuring device,

wherein the coordinate measuring device is configured to measure and output the one or more geometric positions with or without a modular feature pack attached.

2. The coordinate measuring device of claim 1, wherein the coordinate measuring device is configured to receive commands through the single docking portion.

3. The coordinate measuring device of claim 1, wherein the docking portion comprises an electronic connector configured to form an electronic connection with the feature pack.

4. The coordinate measuring device of claim 3, wherein the electronic connection comprises a data transfer connection.

5. The coordinate measuring device of claim 3, wherein the electronic connection comprises a power transmission connection.

6. The coordinate measuring device of claim 1, wherein the docking portion comprises a mechanical connection.

7. The coordinate measuring device of claim 1, wherein the docking portion comprises a thermal connection.

8. The coordinate measuring device of claim 7, wherein the docking portion connects to electronics in the coordinate measuring device by thermally conductive members, allowing substantial heat transfer between the coordinate measuring device and the feature pack.

9. The coordinate measuring device of claim 1, wherein the additional and distinct features or functionalities is processing of data signals.

10. The coordinate measuring device of claim 1, wherein the additional and distinct features or functionalities are temperature controls.

11. The coordinate measuring device of claim 1, wherein the additional and distinct features or functionalities is improved data processing.

12. The coordinate measuring device of claim 1, wherein the coordinate measuring device is an articulated arm coordinate measurement machine.

13. A coordinate measuring device system comprising:

a coordinate measuring device configured to measure and output one or more geometric positions on an object by at least one of contacting a point on the object or positioning the coordinate measuring device so as to view a point on the object, the coordinate measuring device comprising a docking portion; and

two or more feature packs configured to electronically connect to the coordinate measuring device via the same docking portion and wherein a first feature pack provides a first additional electronic feature or functionality to the coordinate measuring device and a second feature pack provides a second additional electronic feature or functionality distinct from the first additional electronic functionality to the coordinate measuring device.

14. The coordinate measuring device system of claim 13, wherein at least one feature pack comprises a tilt sensor.

15. The coordinate measuring device system of claim 13, wherein at least one feature pack comprises a data storage device.

16. The coordinate measuring device system of claim 15, wherein the at least one feature pack comprises instructions for coordinate measuring device operation.
