### Using Adaptive Scanning

Not every user with access to scanning hardware is an expert and understands how to configure various controlling parameters that affect accuracy and throughput, such as scan speed, point density, offset force, and so on. With Adaptive Scanning you don't have to be an expert, since it removes the guesswork out of configuring such scanning parameters. Adaptive Scanning uses a system comprised of expert knowledge to calculate those parameters based on known inputs, such as tolerance, feature type and size, stylus length, and surface finish. You only need to supply the information known to you, and the Adaptive Scanning algorithms perform the work of choosing the other settings.

Adaptive Scanning is also "Controller Aware". This means that if a certain capability exists on a controller which will improve the scanning accuracy and throughput, the software will automatically make use of these capabilities as needed.

Adaptive scanning is made available through the Measurement Strategies tab for these supported Auto Feature types: Circle, Cone, Cylinder, Line, and Plane.

To Use Adaptive Scanning

1. Access the Auto Feature dialog box.

2. Define a feature that supports Adaptive Scanning.

3. Click the >> button that shows the advanced measurement options.

4. From the Probe Toolbox select the Measurement Strategies tab.

5. Select the Adaptive Scan strategy for that feature,

6. Supply all known information about the feature and its tolerances, and PC-DMIS does the rest.

7. To override any automatically configured parameters, click the Advanced tab within the Measurement Strategies tab and mark the Override check box.

8. Click Test to test the scan.

9. When ready, click Create to add the scan into the part program.

Example Adaptive Scan - Adaptive Scanning Setup tab

Sample Adaptive Circle Scan - Adaptive Scanning Setup tab

Adaptive Scanning Setup – This tab configures feature tolerances and surface type. Standard feature parameters such as size and location are specified through the standard portion of the Auto Feature dialog box.

Example Adaptive Scan - Advanced tab

Sample Adaptive Circle Scan - Adaptive Scanning Setup tab

Advanced - This tab lets you choose to override the calculated settings as well as test the scan.

Example Adaptive Scan - Control Element tab

Control Element - This tab is specific to the Adaptive Circle Scan strategy and is used to define whether the circle scan will be done on a cylindrical or spherical shape. You can choose this from the Control Element list on the tab. If you choose Spherical from the list, the vectors of the derived scan are therefore not in the plane of the circle, but are normal to the sphere surface. One use for this scan type is the ISO 10360-4 tests.
