AM1 adjustable module

The AM1 adjustment module is designed to provide quick and accurate angular alignment of the PH6M and PH10M with the axes of the CMM and Renishaw ACR3.

In addition, the quick release mechanism allows the probe heads to be removed for storage and replaced without further alignment. In-built overtravel protection minimises the risk of probe head damage.

Adjusting the AM1

Below are instructions on how to adjust the AM1 in order to align the probe head to the CMM axes. The procedure should be carried out in the order specified:

AM1 adjustment

1.  Roll adjustment - rotate the roll adjusting capstans equally and in opposite directions (i.e. rotate one capstan clockwise and the other anti-clockwise) to adjust roll.

2.  Pitch adjustment - rotate the pitch adjusting capstan to increase or decrease the pitch.

3.  Yaw adjustment -

  1. Release the lock screw.
  2. Rotate the yaw adjusting screws equally in opposite directions to provide the required yaw.
  3. Tighten the screws against each other without applying excessive torque.
  4. Tighten the lock screw

4.  Quick release of the AM1 from shank -

  1. Release the lock screw.
  2. Retract ONE yaw adjustment screw.

NOTE: If repeatability of position is required on re-attachment, DO NOT alter the other screw. This repeatability of position is normally sufficient for alignment with the autochange rack, but probes must be re-qualified for measurement.

5. Re-attachment of AM1 to shank -

  1. Locate the AM1 against the shank and rotate until engaged.
  2. Tighten the yaw adjustment screw.
  3. Tighten the locking screw.
