ACR3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) 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) 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
The MRS 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
(part no. H-1000-5088).

CompatibleRenishawproducts
Renishaw have a number of probe heads and probes that have either the male or female part of the
autojoint fitted to them and are therefore compatible for use with the ACR3. For additional information,
please refer to the relevant product documentation.
Heads
PH10M – A motorised indexing probe head with 720 repeatable positions suitable for all two wire and
multiwired probes.
PH10MQ – This is an in-quill mounted version of the PH10M head.
PH6M – A fixed autojointed probe head suitable for all two wire and multiwired probes.
Probes
SP25 – High accuracy scanning probe enabling the user to scan for form measurement and reverse
engineering, rapid TTP for geometric measurements is also possible.
SP600M – Analogue contact scanning probe which is ideal for profile scanning and it features 300 mm
stylus capability. Permits the CMM to gather large amounts of data very rapidly.
TP7M – High accuracy strain gauge based touch-trigger probe.
TP6A – This is a probe suited to general purpose probing applications offering longer and heavier styli
carrying capability.
OTP6M – An optical trigger probe that uses a visible laser spot to provide a non-contact inspection
solution for CMMs.
Using the Renishaw range of probe adaptor bars (PAA), the complete range of Renishaw M8 probes can
be used in conjunction with the autochange system; a brief description of some of these probes is given
below:
TP20 – A 13 mm diameter kinematic touch-trigger probe consisting of a two piece design that provides
the facility to repeatedly change probe modules without the need for re-qualification.
TP200 – A 13 mm diameter strain gauge based touch-trigger probe consisting of a two piece design that
provides the facility to repeatedly change stylus modules without the need for re-qualification.
TP2 - A 13 mm diameter kinematic touch-trigger probe with adjustable stylus force.
TP6 – A 25 mm diameter kinematic touch-trigger probe of a robust design.
NOTE 1: ACR3 can only be used in the horizonal orientation.

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.
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
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.
NOTE: The Renishaw PH10 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.
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 (see
figure 7):
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.
NOTE: During this procedure the probe should not be qualified.

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
(see figure 8):
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.
NOTE: During this procedure the probe should not be qualified.

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:
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.

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:
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 -
4. Quick release of the AM1 from shank -
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
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
1. Release the lock screw.
2. Retract ONE yaw adjustment screw.
