GB WARNINGS

SAFETY NOTE

Each ACR2 port contains spring-loaded components which cause pinch
hazards if covers are removed.

Do not dismantle ACR2 ports or remove them from their mounting plates.

Return defective units to an authorised Renishaw Customer Service Centre.

Pinch hazards exist between moving parts and between moving and static
parts. Do not hold any part of the Autochange system during movements or
during automatic probe changes.

Beware of unexpected movement. The user should remain outside of the full
working envelope of probe head / extension / probe combinations.

In all applications involving the use of machine tools or CMMs, eye protection
is recommended.

There are no user serviceable parts inside Renishaw ACR2 units. Return
defective units to an authorised Renishaw Customer Service Centre.

For instructions regarding the safe cleaning of Renishaw products, refer to
the MAINTENANCE section of the relevant product documentation.

Refer to the machine supplier's operating instructions.

It is the machine supplier’s responsibility to ensure that the user is made
aware of any hazards involved in operation, including those mentioned in
Renishaw product documentation, and to ensure that adequate guards and
safety interlocks are provided.

Under certain circumstances the probe signal may falsely indicate a probe
seated condition. Do not rely on probe signals to stop machine movement.

The expected method of providing an emergency stop for Renishaw products
is to remove power.

1 INTRODUCTION

The ACR2 autochange system is an arm-changing system for the PHS1
servo positioning head system. It allows probe extensions or probe adapter
arms to be exchanged to suit the probing task required.

Arms are locked or unlocked from the head by motion of the machine itself.
The head engages a rack port and the machine drives the port up to unlock
an arm or down to lock it in position.

No power connections or signal connectors are necessary to the rack,
making installation very simple.

The ACR2 is supplied as pairs of rack ports which are mounted onto a
suitable fixture supplied by the OEM. The system is modular and any number
of port pairs can be used anywhere on the CMM.

1.1 System features

INTRODUCTION

 Modular construction Ports can be positioned in pairs anywhere on

the machine

 Simple concept The change cycle is operated by CMM motion

No power connections are needed and all
sensing and overtravel protection is contained
within the PHS1 servo positioning head itself;
no motors, switches or sensors within the rack

 Expandable concept Any number of racks can be fitted anywhere on

the machine, eg a 4 port rack at one end and a
2 port rack at the other

 Versatile probing ACR2 ports can accommodate touch trigger,

analogue contact or laser scanning probes, with
or without extension bars

 Safe operation Sensors on the PHS1 servo positioning head

detect collisions and check whether arms are
correctly and safely locked in position after a
change cycle. The PHS1 also incorporates an
overtravel mechanism to protect against
collisions

 Sealed arm locations Covers with effective seals protect electrical

contacts and kinematic locations when not in
use

INTRODUCTION

1.2 System description

The ACR2 rack consists of pairs of ports that store arms. The arms are
either head adapters (HA) or head extensions (HE).

The ports allow arms stored in them to be automatically locked and unlocked
onto a PHS1 servo positioning head.

To change probe arms automatically, the CMM must be programmed to
complete a series of movements using positions calculated during the port
datum routine. These movements cause a mechanism inside the port to
rotate a screwdriver which engages a slot on the arm. The slot activates a
cam which, when rotated, locks the arm in place.

Manual fitment of probe arms can be achieved using the S10 autojoint key
supplied.

Arms are located in the rack port on two steel pins which pass through holes
in the arm. A spring-loaded lid secures the arm in position and seals the
spring-loaded electrical contacts and kinematic locations against
contamination.

Signals to indicate when an arm is present on the head and whether the arm
is locked correctly and safely are provided by the servo positioning head.
This ensures that arms are always positively locked on the head.

Crash protection is provided by the head overtravel unit. Any machine move
errors or mis-programmed moves which cause an unexpected collision will
cause the head overtravel to operate, sending a signal to stop the machine.

NOTE

The maximum operating speed of the ACR2 autochange rack should not
exceed 100mm/sec.

2.1 Port pair mounting

The ACR2 autochange system is a modular system with pairs of ports
supplied by Renishaw to be mounted on a suitable fixture. In this way, any
number of racks of two, four, six or more ports can be created and positioned
anywhere on the CMM.

Renishaw do not supply the mounting pillar.

Each port pair can be mounted using four off M8 bolts supplied with the kit
or, if a proprietary extrusion is used, M8 T-slot nuts. Mounting hole positions
for M8 bolt mounting are shown in Figure 2.

2.2 Port pair alignment

1. Mount a pair of ports to the mounting fixture using four off M8 bolts
through the mounting holes shown in Figure 2.

2. Align the port mounting plate, with the use of shims if necessary, such
that the front face is aligned to the machine axes within ±0.1° (0.5mm
runout) and the runout on the top face is within 0.5mm.

Two off M8 screws (supplied in the port pair kit) can be used in the
adjustment holes (see Figure 2) to assist in aligning the port pair.

2.3 Port pair alignment checking procedure

In order to check the alignment of a port pair, the following procedure should
be used:

 Place the tool onto the alignment pins, as shown in Figure 4, ensuring

the alignment pins are seated in the levelling tool vee grooves.

 If the port is correctly aligned, the bubble should be central within the

graticule.

INSTALLATION

This section gives a suggested method for datuming an ACR2 autochange
rack port and the recommended CMM movements for change cycles using
that datum position.

4.1 Port datum procedure

This method allows datuming of each ACR2 port by taking probing points on
one of the location pins.

1. Qualify the PHS and probe combination as shown below

Note that the probe tip must be qualified before the port can be
datumed. Refer to the PHS Calibration Guide H-1000-4048 for
recommended probe calibration procedure.

A typical probe assembly suitable for port datuming would be

 HA8 probe arm

 TP2 probe

 PS17R 20mm stylus

Nominal offset values for this probe assembly are

 RD 72mm

 RE 104mm

The values RD and RE should be established to within ±0.1mm by the
probe qualification procedure.

Note also the angular orientation of the D and E axes required for port
datuming (D 0°, E 0°). The probe tip should be aligned to the axis
origins to within 0.1°.
