Sphere Compensation Method - 7-Axis

1238888

Perform the Sphere Compensation using a precision sphere or tooling ball. The sphere should be at least 10 mm (0.375 in) diameter or larger. You will digitize 44 individual points in two specific locations around the sphere by pressing the green Front button for each.

7-Axis Sphere Compensation

Select the Guidance check box to use position guidance. Guidance monitors the position and rotation of the handle during the recording of the compensation points.
Click Start Compensation.

If you are using the ScanArm Extension Adapter and have created an angled probe, click the check box to record a rotation position point during the probe compensation. See Using the ScanArm Extension Adapter.

The ball probe must remain in contact with the sphere while digitizing points. Even one or two poorly digitized points significantly affects the optimization process, which then has an effect on the accuracy of the ScanArm.

Move the handle so that the probe is pointing in position #1.
Digitize 11 points around the top hemisphere of the sphere with the probe pointing in position #1. Hold the handle in the same direction and orientation for every point. Watch the live guides at the bottom of the screen to ensure the direction and orientation remain the same for all points.
Rotate the handle 90 degrees.
Digitize 11 points around the top hemisphere of the sphere with the probe pointing in position #1. Hold the handle in the same direction and orientation for every point.
Move the handle so that the probe is pointing in position #2.
Digitize 11 points around the front hemisphere of the sphere with the probe pointing in position #2. Hold the handle in the same direction and orientation for every point.
Rotate the handle 90 degrees.
Digitize 11 points around the front hemisphere of the sphere with the probe pointing in position #2. Hold the handle in the same direction and orientation for every point.

The digitized compensation points then calculate and the Compensation Status updates.

Click Save and Exit to store the probe compensation in the list. See Probe Compensation List.

If the probe passes, the current date and time is added to the probe information.
