Introduction

The autochange system documentation is covered by two guides:

This user's guide which gives a simple explanation of the equipment, details of alignment procedures and fault-finding information

An installation and programmer's guide (Renishaw part number H-1000-6012) which describes system functions, installation and

datuming together with software and programming information

It is intended that the user's guide is the reference document for the working CMM installation, and that the installation and programmer's

guide is the reference document for the CMM manufacturer.

The autochange system

General description

Renishaw's ACR1 is a fully integrated 8 port probe exchange system. Mounted within the CMM's working envelope, the autochange system

facilitates fast, automatic probe exchange without the need for re-qualification of the probe assembly.

Fast probe exchange cycles are achieved by the probe head docking the original probe and selecting a new one. The high repeatability of the

autojoint removes the need to re-qualify between moves.

The autochange system consists of an autochange rack, an autochange controller and an autochange head which, together with a mounting

kit and cables, form a complete kit.

ACR1 autochange rack

The ACR1 autochange rack is the functional part of the system which is located within the CMM working volume. It is powered and controlled

by the ACC2-3 controller via a rack cable which can be up to 30 metres (98 feet) long.

The ACR1 stores up to eight 25 mm diameter autojointed probe and extension bar combinations which can be exchanged automatically by

the CMM. The ACR1 can be mounted in either the horizontal or vertical orientation depending on the application.

The two cut-aways on the ACR1 are to allow larger diameter probes to be used, such as SP600M. In this case special short ports are required

making the ports either side of the probe redundant (or with limited use).

A full set of short ports (i.e. eight) are supplied with the ACR1 allowing the rack to be fully customised.

Datum probe

The rack includes a fixed touch-trigger datum probe at its left end which incorporates a datum stylus and an alignment stylus. This datum

probe is used to align the probe head to the ACR1.

Datuming the probe head autojoint on the datum stylus relates the position of the head to the rack, and the location of the probe

configurations held within the rack. The alignment stylus is included to assist with the head alignment.

Sensing system

The rack performs probe change routines using light beams to detect the probe head and includes motor-driven screwdriver blades to lock

and unlock the probes. The light beams are located in front of and behind the probe docking port lids, and a light beam sensing system

determines which function to perform by monitoring which light beam is broken first.

If the front beam is broken first, this indicates to the system that the head is entering the port with either a probe or extension bar attached -

the screwdriver blades will be set to the locked position to enable the head to dock correctly.

If the rear beam (within the main unit) is broken first, this indicates that an empty probe head or extension bar is entering the rack - the

screwdriver blades will be set to the unlocked position. After both beams have been broken, the system waits for the appropriate command

or time to lock or unlock the probe.

There is a limited ovetravel and crash protection facility built into the rack. If it is deflected by more than 1 mm (0.039 in) it sends a STOP

signal to the CMM control to stop the machine.

* See 'Fault finding' section for error mode analysis.

ACC2-3 controller

General description

The ACC2-3 autochange controller is the intelligent part of the system. It handles the communications to and from the CMM controller,

controls the ACR1 autochange rack, and multiplexes and interfaces the head and rack probe signals.

Front panel

The following figure shows the arrangement of the ACC2-3 front panel. Descriptions of the functions of the switch and LEDs follow.

1 POWER ON LED (green)

Powered from an internal power rail, this LED indicates that the unit is switched on.

2 PROBE SEATED LED (yellow)

Indicates the status of the selected probe. When the probe interface circuit is active, this LED will be ON. In this condition the LED will be OFF

when the stylus is deflected.

NOTE: This LED is only operational when the internal probe interface is selected.

3 RACK READY LED (yellow)

Indicates the status of the rack. The LED is OFF when the rack is active. A flashing LED indicates that the system is in datum mode 1 (see

'Operating modes' section, mode 6).

4 RACK ACTIVE LED (yellow) *

Indicates that the rack is performing a lock or unlock procedure. A flashing LED indicates that the system is in datum mode 2 (see 'Operating

modes' section).

5 LOCK ERROR LED (red) *

Indicates that a fault has occurred during a lock or unlock procedure.

6 OVERTRAVEL ERROR LED (red) *

Indicates that the rack has been overtravelled or an excessive entry speed condition has been detected.

7 STOP LED (red)

Indicates that the ACC2-3 has asserted the PICS STOP signal following a critical failure.

* Various combinations of these LEDs are used to indicate other fault conditions (see 'Operating modes' section, 'Mode 4 - Error mode).

8 RESET

The RESET switch initiates a complete software restart. It is used for resetting the system after a collision, or for putting the system into or out

of datum mode 1 (mode 6). To take effect, the button must be pressed for at least 100 ms.

Autojoint system

The Renishaw autojoint is a highly repeatable joint which is fitted to certain probe heads, eliminating the need to re-qualify the probe after a

probe change.

The autochange system requires a probe head fitted with an autojoint. Renishaw have a number of probe heads and probes that have either

the male or female part of the autojoint fitted to them. Listed below is a brief description of each. For additional information, please refer to

the relevant product documentation.

Heads

PH10M PLUS - A motorised indexing probe head with 720 repeatable positions suitable for all two wire and multiwired probes.

PH10MQ PLUS - This is an in-quill mounted version of the PH10M PLUS head.

PH6M - A fixed autojointed probe head suitable for all two wire and multiwired probes.

Probes

SP25M - 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. Enables 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: If a probe extension bar is manually locked (using an S10 autojoint key), it is advisable to lock it fully to the cam end stop

then back the screwdriver slot off by approximately 5. If this is not done, it is unlikely that the probe will dock into the autochange

rack.

Aligning the head

AM1 adjustment module

The AM1 adjustment module is designed to provide quick and accurate angular alignment of the PH6M or PH10M PLUS motorised probe

heads with the axes of the CMM and the Renishaw autochange rack.

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.

Adjust the AM1 in the order given:

1 Roll adjustment

Rotate the roll adjusting capstans equally and in opposite directions (i.e. rotate one capstan clockwise and the other anti-clockwise).

2 Pitch adjustment

Rotate the pitch adjusting capstan to increase or decrease the pitch.

3 Yaw adjustment

Release the lock screw. Rotate the yaw adjusting screws equally in opposite directions to provide the required yaw. Tighten the screws

against each other without applying excessive torque. Tighten the lock screw.

4 Quick release of AM1 from shank

CAUTION: Quick release is only possible if the lock screw is omitted.

Release the lock screw.

Retract ONE yaw adjusting 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.

Rotate the AM1 until free and remove.

5 Re-attachment of AM1 to shank

Locate the AM1 against the shank and rotate until engaged. Tighten the yaw adjustment screw.
