Hole Compensation Method

1238888

Perform the Hole Compensation using the FARO probe compensation cone or a 5 mm (0.2 in) diameter machine drilled hole. The hole does not have to be exactly 5 mm (0.2 in), but it must be smaller than the probe’s diameter and have a smooth seat.

Hole 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.

Collect all of the points in this method by holding down the green Front button. The ScanArm will collect points as fast as possible (“scanning”) until you release the green Front button.

  1. Place the ball probe in the compensation cone. Start in a vertical position.

  1. Digitize points in the compensation cone and sweep to position #1.

  • Press and hold the green Front button and move the handle down until the shaft of the probe is parallel with the top of the cone.

  1. Release the green Front button and move to the next position.

To remove any unwanted points, press and hold the red Back button.

  1. Digitize points in the compensation cone and sweep to position #2.

  • Press and hold the green Front button and move the handle down until the shaft of the probe is parallel with the top of the cone.

  1. Release the green Front button and move to the next position.

  1. Digitize points in the compensation cone and sweep to position #3.

  • Press and hold the green Front button and move the handle down until the shaft of the probe is parallel with the top of the cone.

You must digitize at least 200 points in the three sweeps. If your point count is less than 200, simply repeat each sweep.

  1. Press the red Back button to finish.

 

7-Axis ScanArms have an additional position. Rotate the handle.

  1. Digitize points in the compensation cone and rotate the handle.

  • Press and hold the greenFront button and rotate the handle.

You must digitize at least 50 points in this position.

  1. Press the redBack button to finish.

 

The probe must be well-seated in the hole when digitizing all compensation points. Even one or two poorly digitized points significantly affects the optimization process, which then has an effect on the accuracy of the ScanArm.

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

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