System and method for measuring using multiple modalities

1. A method of measuring an object using a coordinate measuring machine (“CMM”) having a CMM probe and a CMM accuracy and a CMM coordinate system, the object having a plurality of portions, the method comprising:

providing a jogbox with a 3D scanner having a scanner accuracy, the 3D scanner being distinct from the CMM probe, the jogbox and 3D scanner movable with respect to the CMM;

positioning the object on the CMM;

performing a two-part measuring process on the object using each of two modalities, the two-part measuring process comprising:

(1) using the 3D scanner, scanning the object to produce scan data of the object, and measuring a first portion of the object using the scan data to produce measurements of the first portion; and

(2) measuring a second portion of the object using the CMM probe to produce measurements of the second portion, the second portion being different from the first portion, the second portion not overlapping the first portion; and

the CMM accuracy being more accurate than the 3D scanner accuracy.

2. The method as defined by claim 1 , further comprising:

determining that the first portion is to be measured from the scan data; and

determining that the second portion is to be measured using the CMM.

3. The method as defined by claim 1 wherein the scan data comprises a point cloud representation of a portion of the object.

4. The method as defined by claim 1 , wherein the 3D scanner comprises at least one of a laser scanner and a white light scanner.

5. The method as defined by claim 1 wherein the 3D scanner has a scanner frame of reference that is different from the coordinate system of the CMM, the method further comprising reconciling the scan data with data produced by the measurement probe of the CMM to produce reconciled scan data, the reconciled scan data sharing a common frame of reference with the data produced by the measurement probe of the CMM, and wherein

measuring the first portion comprises locating the first portion of the object as represented by the scan data, and virtually measuring that located first portion.

6. The method as defined by any one of claim 1 wherein the scan accuracy is between about 50 and 200 microns and the CMM accuracy is between 1 and 10 microns.

7. The method as defined by claim 1 wherein the jogbox includes a joystick for controlling the CMM, and a touch-screen display for controlling the jogbox and/or the CMM.

8. The method as defined by claim 1 further comprising comparing the measured values of the first and second portions against a nominal file to determine error.
