How To - Calibrating Probe Head
In the event of a probe crash, the probe head may become misaligned, causing unintended probing errors. One way to quickly isolate and determine if this is the issue involves:
- Selecting the A0B0 reference tip
- Clear the tip calibration by:
- Updating the probe assembly, or
- Attempt to calibrate the probe and cancel the operation afterward
- Measure the calibration sphere
- Set origin to the sphere
- Select the opposing A90 probe angles. i.e., A90B0 and A180B0
- Measure the same sphere
- Report the position of the subsequent measurements
The values should be close to zero or within a reasonable deviation.
If this is not the case, re-determining the probe head matrix may be necessary.
Follow the steps below to begin the calibration:
- Launch CMM-Manager online
- Switch to the System ribbon tab
- Select Machine Setup from the Setup group
- If this is the first time you are launching the setup, enter "service" when prompted for a password
- Switch to the Probe tab
- Select Calibrate from the Probe Head group
- Follow the instructions as prompted to complete the calibration.
