Mechanical safety
• When setting up and mounting Renishaw XM and XC-80 systems beware
of pinch and/or crush hazards that may be created e.g. due to magnetic
mounting bases.
• Beware of trip hazards that may be created when using the XM and XC-80
systems, e.g. due to trailing cables.
• Exercise caution if components are to be mounted to moving or rotating
machinery. Beware of cables becoming entangled.
• Exercise extreme caution if XM and XC-80 system components are to be
mounted to machinery that may accelerate rapidly or move at high speed,
which could lead to items colliding or being ejected.
• If it is necessary to operate the machine with the guards or any safety
feature removed or disabled, it is the responsibility of the operator to
ensure that alternative safety measures are taken in line with the machine
manufacturer’s operating instructions or relevant codes of practice.
• If you are using a part program or error correction parameters generated by
the Renishaw software, it is the responsibility of the user to validate these
at low feedrate and be prepared to operate the emergency stop button if
necessary.
• The XM system weighs approximately 24 kg in the case (31 kg with the
machine tool fixturing kit attached). Users should exercise caution and follow
local manual handling guidelines.
Laser optical safety
• In accordance with (IEC) EN60825-1, XM systems are Class 2M lasers and
safety goggles are not required (under normal circumstances the eye will
blink and look away before damage can occur).
• Do not stare directly into the laser beams or view them with optical
equipment such as telescopes, convergent mirrors or binoculars as
permanent retinal damage could occur. Do not direct the beam at other
people or into areas where people unconnected with laser work might be
present. It is safe to view a diffuse-reflected beam during system alignment.
• FDA compliance (USA) – complies with 21CFR1040.10 and 1040.11 except
for deviations pursuant to laser notice no. 50, dated 24 June, 2007.
Rotating the shutter to the closed position (the right hand position on the picture)

inadvertently.
EU REACH SVHC compliance
Please see the relevant battery manufacturer’s website for further information:
Varta: http://www.varta-microbattery.com/en/news-downloads/downloads.html
Fibre optic safety
The XM system contains fibre optics. In the unlikely event that the flexible steel
conduit is cut or severed, fibre optic splinters may be produced.
Fibre optic splinters can be very small and extremely sharp. Should any fibre
optic splinter become embedded in the skin, medical attention should be sought
immediately.
Should the fibre optic become damaged, the following procedure should be
followed (be aware that the affected area might contain splinters of unattached
fibre optic which can present a hazard):
• immediately power down the XM system,
• wear eye protection and protective gloves when handling damaged or
exposed fibre optics,
• carefully remove the XM system from the machine and package in a suitable
thick-walled cardboard box, clearly marked ‘Caution: exposed fibre optics,
handle with care’ on the outside of the box,
• return the unit to the nearest Renishaw office.
No attempt should be made to repair or dismantle the fibres from the laser unit.
Note: Fibre optic splinters do not show up on X-rays.
The use of this symbol on the batteries, packaging or accompanying documents
indicates that used batteries should not be mixed with general
household waste. Please dispose of the used batteries at a
designated collection point. This will prevent potential negative effects
on the environment and human health which could otherwise arise
from inappropriate waste handling. Please contact your local authority
or waste disposal service concerning the separate collection and
disposal of batteries. All lithium and rechargeable batteries must be
fully discharged or protected from short circuiting prior to disposal.

XM multi-axis calibrator
XM multi-axis calibrator is a laser measurement system capable of measuring six degrees of freedom:
• along a linear axis
• in any orientation
• from a single set-up
The measured errors are:
• Linear positioning of the axis
• Angular rotation in the vertical plane (pitch)
• Angular rotation in the horizontal plane (yaw)
• Straightness deviation in the vertical plane
• Straightness deviation in the horizontal plane
• Roll about the linear axis of travel
Principles of measurement
XM multi-axis calibrator
Page 13
13
XM multi-axis calibrator
The XM system uses three laser beams (1,2 and 3) to measure the linear, pitch
and yaw errors using interferometry. The light emitting diode (LED) beam (4) is
used for straightness and roll measurements.
The basic measurement concept is:
Angular
The three interferometric beams provide a linear measurement
of the separation between launch and receiver. Because the
distance between these beams is known, angular errors of pitch
and yaw can be determined by the system.
Linear
Using the pitch and yaw measurements, the linear error is
determined based on the combination of beams 1, 2 and 3 to
calculate the linear error at the position of beam 4.
The 4th (diode source) beam is used to measure straightness and roll.
Straightness
The vertical and horizontal straightness error is measured using
a position sensor within the receiver and transmitted back to the
laser via wireless communication.
Roll
Roll measurement is performed optically using a roll detector
inside the receiver. Roll measurements are absolute between
the launch and the receiver.

Calibration software kit
The XM system is supplied with the “Calibration software kit” which comprises:
• CARTO suite
• User guides and documentation for XM, XL-80, XC-80 and XR20-W
The CARTO suite features two applications:
Note: XM-600 supports additional functionality when
used on a CMM which is equipped with Renishaw’s
UCC system. This functionality is accessed using UCC
Assist, which is part of UCC Suite - a software package for the
CMM controller. XM-600 is supported from UCC Suite V5.4.
UCC Assist enables additional features which are unique to
XM-600, and contains support information on how to use XM600 to calibrate a UCC-equipped CMM.

XM multi-axis calibrator
XC-80 environmental compensator
The XM specified accuracy for interferometric measurements is only valid when
used with a calibrated XC-80 environmental compensator.
Changes in air temperature, pressure and relative humidity affect the wavelength
of the laser light and, therefore, the measurement readings taken.
The XC-80 environmental compensator and its sensors very accurately measure
the environmental conditions and compensate the wavelength of the laser beam
for variations in air temperature, air pressure and relative humidity.
Note: For full details on XC-80 operation and specification please refer to
XC-80 user guide.

Other accessories for use on CMMs
Additional accessories are available to allow flexible use of the XM system (see Appendix E). These can be used to:
Pan / Tilt Adaptor
• Elevate the launch unit. This may be
useful when the machine has otherwise
insufficient axis travel to move receiver
to required position.
• Use the XM system when there are no
convenient mounting surfaces that are
parallel or perpendicular to the direction
of machine travel.
• Rapidly change launch unit orientation
between horizontal and vertical.
CMM table plate adaptor
• Provide a base on which to support the launch unit when a convenient
magnetic surface is not available on the machine (compatible with threaded
hardware up to M12).
• Overhang the XM launch unit to enable the full travel of an axis to be
measured.
Steel mounting plate
• Provide a repeatable, magnetic
mounting point for the XM launch unit
and the 90° bracket, such as on the
length bar plate, pan/tilt adaptor or
customer-designed fixturing.
Machine optics mounting kit
• Use the XM system where a
magnetic mounting location for
the receiver is not convenient.
• Assemble lightweight mounting
solutions for the XM receiver.
• Quickly and conveniently mount
the XM receiver onto the quill of
a CMM in place of a Renishaw
head.

Setting up a test
Testing precautions
Light interference
External light can cause errors in roll measurement performance.
To minimise the effect of light interference the user should:
• Always use the beam shroud
• Switch off the machine lighting
• Minimise external lighting
Sources of lighting that can affect the performance are:
• Sunlight
• Flashing beacons
• Welding
• LED and fluorescent room lighting
Performance can be affected by abnormal changes in any of the above. It is
important to consider light effect and reflections over the full range of the axis
under test.
CARTO allows the user to perform an ambient light check. See Capture user
guide for details.
Page 23
23
XM multi-axis calibrator
Testing precautions
Thermal stabilisation
• To meet the quoted specifications the XM system must be thermally stable.
• Thermal stability is achieved 45 minutes after the laser/launch and receiver
are powered on. Therefore it is recommended to turn the laser/launch and
receiver on at the earliest opportunity.
• The receiver and the launch must be removed from the case during the
thermal stabilisation period and should be placed at least 200 mm away from
each other.
• To avoid the need for further thermal stabilisation, once discharged the
receiver battery should be changed within 30 seconds:
Mechanical set-up
• In order to take relative measurements between the tool and the workpiece,
the launch must always be attached to the structure that holds the
workpiece, i.e. the machine bed or the chuck on a lathe. See Appendix F for
XM set-up best practice.
• When the XM system is used on a
machine where the workpiece moves,
the conduit should be fixed to the
machine bed to stop it dragging,
misaligning, or causing the launch
to move during machine motion.
Magnetic cable clamps are included
in the kit for this purpose.
• There may be situations when sufficient magnetic force is not available to
securely mount the launch unit. This could occur when there is a requirement
for overhanging the launch unit, or the machine bed is not magnetic. In this
case, additional fixturing components (such as the Machine Tool Fixturing Kit
or other mounting accessories) may be required.
• In general, metrology performance is improved when the system is
used with fewer accessories. Use only the minimum amount of fixturing
components required to align the system to the axis under test.
Note: An uninterruptible power supply can be used when moving
XM from one machine to the next.

Basic rules of alignment
1. Launch and receiver are close to each other = translation adjustment
2. Launch and receiver are far from each other = rotation adjustment

XM multi-axis calibrator
Visual axis alignment
Visual axis alignment is performed using the target on the front of the receiver.
Translate the machine so that one of the beams is on the
receiver target
Open the shutter on the launch and the receiver
Visually check the launch and the receiver are parallel to
each other
Move the launch and the receiver as close to each other
as possible
Set the pitch and yaw adjusters to the middle of their travel

Receiver alignment
• To maintain the system accuracy the launch and the receiver must be
parallel to each other.
• The software will check the parallelism on the completion of the fine axis
alignment.
• If the parallelism tolerance is not met when selecting Capture, the software
will prompt the user to physically adjust the mounting of the receiver. Rotate
the receiver until the red border disappears. Do not adjust the pitch and yaw
adjustment of the launch unit.
Note: It maybe necessary to perform minor translation of the
machine after this step is complete.
Note: Once set-up is complete and before capturing data, it is
recommended to perform an ambient light check. See Capture user
guide for details.

Data capture
Roll tuning
When Start is selected the system will perform a calibration cycle on the roll
detection scheme to compensate for the set-up conditions.
Sign detection
To ensure the errors of the machine are measured with the correct sign (+/-) it
is important that the coordinate system of the XM (X,Y,Z and their directions) is
labelled according to that of the machine. Further details on sign detection can be
found here.
There are two methods of sign detection:
• Automatic
Part programs produced with CARTO will perform machine moves to detect
the sign.
• Manual
The user can manually jog the machine ±150 µm in each axis when
prompted by the software to perform sign detection.
Note: Users can skip an axis if they don’t have three perpendicular
axes. Further details can be found in the Capture user guide.
On completion of these steps the system will start capturing data.

• Ensure the laser/receiver are warmed up as per recommendations
before testing. Specifications - warm up time.
• If the receiver battery has been replaced, follow the thermal
stabilisation recommendations.
• Avoid excessive handling of the launch/receiver to avoid body heat
exchange
• If using custom mounting parts, ensure they are suitable to avoid
thermal growth

Care and handling
System
• It is recommended to store the XM in the system case when not in use.
• Do not attempt to clean the system with water or other fluids.
• Avoid exposure to oil and coolant.
• Do not direct the air lines at the XM.
• Do not expose the system to impact.
Conduit
• Ensure the conduit is not pinched, crushed or stretched. If damaged, consult
the Fibre optic safety section.
• When storing in the case, twist the launch whilst vertical to allow the conduit
to coil.
• If the laser is left in the case during measurement, do not close the lid of the
case to avoid damage to the conduit.
• Fix the conduit using the magnetic cable clamps to ensure the conduit does
not drag, misaligning the launch.
− Manually check the movement of the axis over the full range of the test,
before running a test.
• Never hold the laser or launch by the conduit.
Optics
Cleaning of the optics should be a last resort
To maintain system performance, the XM optics must be kept clean by
following good handling practice:
• Close the receiver and launch shutters when not in use.
• Do not touch the optical surfaces.
• Minimise use in contaminated atmospheres.
Cleaning recommendations
• Only use approved solvents for cleaning the optics: Methylated spirit and
optical grade IPA only (methylated spirit is preferred to IPA).
• Wipe only with non-abrasive lens tissue or lint-free cloth wrapped around a
cotton bud (do not use a cotton bud directly on the optic as this may increase
debris).
• Clean the optics using a gentle action. Never use a scrubbing action as this
might damage the coatings.
Failure to follow these recommendations may lead to damage to the coatings and
glass elements of the optics.

Using the 90 degree bracket
The 90 degree bracket can be used in two orientations (standard and reverse).
Reverse orientation allows the launch to be mounted from the side of the machine
tool bed to maximise the length of the axis that can be measured.
When using the 90 degree bracket the user must clock the side face of the
bracket to ensure it is parallel to the axis of travel (e.g. if measuring Z on a vertical
machining centre, clock one of the faces of the 90 degree bracket to the X or Y
axis of the machine).
Standard orientation Reverse orientation Clocking the side face of the bracket

Sign detection
XM system has 6 measurement channels:
• 3 channels (T1,T2 and T3) correspond to translations (linear and
straightness)
• 3 channels (R1, R2 and R3) correspond to rotations around T1,T2 and T3
Sign detection process performs the following:
• Links the T1,T2 and T3 axes of the XM to the machine linear axes
• Sets the sign (+/-) of the T1,T2 and T3 measurements
• Sets the sign (+/-) of the R1,R2 and R3 measurements

Appendix F
Straightness measurement
Consider a tool machining a component on a machine bed. As the bed moves
from right-left, errors in the machine cause the height of the tool to vary above
the bed.
To measure this effect we measure the height between the tool and the bed
at ‘intervals’ along the movement of the axis. The error is the variation from a
straight line.
Error
Placing the launch unit on the bed of a machine the laser beam becomes the
reference. Variations in height are detected by the receiver as the machine moves
left-right.
Page 65
65
XM multi-axis calibrator
Angular errors
Angular errors (rotations while moving) will cause a variation in
the height difference between the tool and machine bed. This
height variation is also seen on the XM system measurement.
The measurement is not influenced by the exact position of the launch unit ... … but it is affected by the position of the receiver.
The receiver should be positioned as close as possible to the
centre line of the spindle.
Page 66
66
XM multi-axis calibrator
For relative measurements between the tool and the bed/component, the launch
unit must always be mounted on the bed of the machine.
The receiver must always be mounted on centreline of the spindle.
Measurement comparisons
Measurements taken with the launch unit on the bed of
the machine are equivalent to running a dial indicator
along a ‘straight edge’ mounted to the surface of the bed.
XM set-up best practice
If the launch unit is mounted
in the spindle, angular errors
can cause errors in the
straightness measurement.
At the point measured
below there is zero height
variation between tool and
bed, but the XM system
would show a deviation
because of the rotation of
the bed.
