System description
Renishaw's ACR3 is a four port rack that facilitates fast, automatic probe exchange without the need for probe re-qualification. The ACR3 is a
four port mechanical design that traverses the MRS rail. Driven by the motion of the CMM, it locks and unlocks the autojoint between the
probe and the probe head. In addition, the ACR3 provides covered storage and protection for up to eight probes and extension bars (two
four port systems can be linked to provide an eight port system).
Mounted within the CMM's working envelope, the ACR3 is combined with the modular rack system (MRS / MRS2) to form an automatic
change rack for probes and extension bars that incorporate the Renishaw autojoint. Each rack port is of modular design to permit easy
replacement should wear occur during the operational life of the ACR3.
Fast probe exchange cycles are achieved by the probe head docking the original probe and selecting a new one. The autochange system
consists of a four port autochange rack (ACR3) and the modular rack system (MRS / MRS2) as shown below.

Autojoint
The autojoint (shown below) is a highly repeatable kinematic joint, one half of which is attached to the probe head, the other half to a probe,
extension bar or adapter.
Locking and unlocking of the autojoint is achieved either manually, using an autojoint key, or automatically, using the autochange rack
system. In all cases, the repeatability of the autojoint eliminates the need for probe requalification after each probe exchange.
MRS / MRS2
The MRS / MRS2 is the common mounting platform for the ACR3, SCP600 (stylus change port for SP600) and FCR25 (flexible change rack for
SP25M). It is available in a number of different overall lengths and heights. For a detailed explanation of this system, please refer to the MRS
installation and user's guide (Renishaw part number H-1000-5088) or the MRS2 installation guide (Renishaw part number H-1000-5255).

Head alignment for ACR3
It is necessary for the probe head to be aligned with both the movements of the CMM and the ACR3. This is because the autojoint is a high
force mechanical joint that could cause operational errors if used with an incorrectly aligned ACR3.
NOTE: The Renishaw PH10 PLUS motorised head system has been designed so that the roll and pitch of the autojoint is held
within the tolerances required for the ACR3 system, when connected to a standard Renishaw shank.
In the majority of installations only the yaw of the motorised head requires alignment. However, it is possible that the location of the probe
head shank to the CMM quill, or the mounting face of the PH10MQ PLUS to the CMM quill, is not held to the required tolerances. In some
cases, this could result in excessive ACR3 port wear or failure of the ACR3 to change probes.
This problem can be rectified by using either the AM1 or AM2 adjustment module.

Alignment of the head - roll
The roll axis of the head is from the left-hand side to the right-hand side of the probe head. The maximum recommended alignment
error is 0.2°.
The recommended procedure for setting the roll of a motorised or indexing probe head is as follows:
NOTE: During this procedure the probe should not be qualified.
1. Index the probe head to an A‐axis position of 90° and a B‐axis position of ‐90°.
2. Using the probe attached to the probe head, measure the qualification sphere on the CMM table (sphere 1). Use the centre of this
measured sphere as a datum.
3. Index the probe head to an A‐axis position of 90° and a B‐axis position of 90°.
4. Using the probe attached to the probe head, measure the qualification sphere on the CMM table (sphere 2).
5. Calculate the roll angle for the probe head using the following formula:
arc TAN {Z axis position of sphere 2 / Y axis position of sphere 2} = Roll angle ﴾recommended <0.2°﴿
6. If the roll angle exceeds 0.2° then adjustment is required, please refer to ‘Adjusting the AM1' or ‘Adjusting the AM2' as appropriate and
repeat steps 1 to 5.

Alignment of the head - pitch
The pitch axis of the head is from the front of the probe head (where the LED is located) to the rear of the probe head. The maximum
recommended alignment error is 0.2°.
The recommended procedure for setting the pitch of a motorised or indexing probe head is as follows:
NOTE: During this procedure the probe should not be qualified.
1. Index the probe head to an A‐axis position of 90° and a B‐axis position of 0°.
2. Using the probe attached to the probe head, measure the qualification sphere on the CMM table (sphere 1). Use the centre of this
measured sphere as a datum.
3. Index the probe head to an A‐axis position of 90° and a B‐axis position of 180°.
4. Using the probe attached to the probe head, measure the qualification sphere on the CMM table (sphere 2).
5. Calculate the pitch angle for the probe head using the following formula:
arc TAN { Z axis position of sphere 2 / X axis position of sphere 2 } = Pitch angle ﴾recommended <0.2°﴿
6. If the roll angle exceeds 0.2° then adjustment is required, please refer to ‘Adjusting the AM1' or ‘Adjusting the AM2'as appropriate and
repeat steps 1 to 5.

Alignment of the head - yaw
The yaw axis of the head is the rotational axis of the probe head with respect to the quill of the CMM. The maximum recommended
alignment error is 0.2°.
The recommended procedure for setting the yaw of a motorised or indexing head is as follows:
NOTE: During the procedure the probe should not be qualified.
1. Index the probe head to an A‐axis position of 0° and a B‐axis position required for an autojoint probe to enter the ACR3.
2. Using the probe attached to the probe head, measure the qualification sphere on the CMM table (sphere 1). Use the centre of the measured
sphere as a datum.
3. Index the probe head to an A‐axis position of 90°, maintaining the same B‐axis position as in step 1.
4. Using the probe attached to the probe head, measure the qualification sphere on the CMM table (sphere 2).
5. Calculate the yaw angle of the probe head using the following formula:
arc TAN { X axis position of sphere 2 / Y axis position of sphere 2 } = Yaw angle ﴾recommended <0.2°﴿
6. If the yaw angle exceeds 0.2° then adjustment is required, please refer to ‘Adjusting the AM1' or ‘Adjusting the AM2' as appropriate and
repeat steps 1 to 5.

Adjustment modules
AM1 adjustable module
The AM1 adjustment module is designed to provide quick and accurate angular alignment of the PH6M and PH10M PLUS 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:
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.
Pitch adjustment
Rotate the pitch adjusting capstan to increase or decrease the pitch.
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.

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.
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.
AM2 adjustment module
The AM2 adjustment module is designed to provide quick and accurate angular alignment of the PH10MQ PLUS motorised probe head with
the axes of the CMM and Renishaw ACR3.
The AM2 consists of the adjuster plate, which is attached to the quill of the CMM, and a set of adjusters fitted to the flange of the head.
The probe head is fixed to the adjuster plate by a pair of captive screws.
The AM2 incorporates a quick release mechanism that allows the same probe head to be removed for storage and refitted without further
alignment.
NOTE: If repeatability of position is required on re-attachment, only the securing screws should be released. Do not alter the other
screws. This repeatability of position is normally sufficient for alignment with the autochange rack, but probes must be requalified
for measurement.

Adjusting the AM2
A special tool is supplied, consisting of a concentric hexagon key and socket spanner. This should be located on the adjusters and locknuts
recessed into the face of the head mounting flange.
NOTE: Springs are fitted under the adjuster locknuts to provide some preload during set up.
The procedure to use this tool is:
1. Slacken the locknut slightly using the outer part of the tool.
2. Set the adjuster using the inner part of the tool.
3. While holding the adjuster stationary with the inner part of the tool, tighten the locknut using the outer part of the tool:
Roll adjustment: Using the AM2 tool and the procedure given above, adjust the roll adjustment screw on the AM2.
Pitch adjustment: Using the AM2 tool and the procedure given above, adjust the pitch adjustment screw on the AM2.
Yaw adjustment: Using the AM2 tool and the procedure given above, adjust the yaw adjustment screw on the AM2.
4. Tighten the two securing screws.
NOTE: Tightening the securing screws could cause the roll, pitch or yaw alignment to change. It is therefore recommended that the
alignments are checked after this procedure.
