System description
The RSP3 range of probes gives REVO users the ability to carry cranked stylus arrangements and enhanced capability for carrying long styli.
The RSP3-1 / 2 / 3 / 4 probes can be used for both 3D-scanning (X, Y, Z) and touch-trigger applications. They enable accurate scanning
measurement with effective stylus lengths ranging from 20 mm - 394 mm. The RSP3-6 probe, on the other hand, provides REVO with
enhanced capability for carrying long cranked and straight styli. RSP3-6 can be used for 2D scanning and 3D touch-trigger applications. It
carries straight extensions up to 800 mm from REVO's A-axis centre of rotation, and cranked extensions up to 600 mm from REVO's A-axis
centre of rotation.
The RSP3 range uses 3-axis scanning with fixed REVO head angles during measurement. Each probe is designed to provide optimized
accuracy and contact force over a specified stylus range. Consequently, the RSH3 stylus holders are intended to fit only with their respective
RSP3 probe.
Design principles of the RSP3 scanning probes
RSP3 uses an optical transducer sensor and a pivoting motion system similar to that found in SP25M system.
The probe's pivoting motion system has two diaphragm springs. One of the RSP3 springs allows movement in all directions whilst the other
(pivot) spring is stiff in (probe) X and Y, but allows movement in Z. Its optical transducer sensor system has two infrared light emitting diodes
that project invisible infrared beams on mirrors mounted on the pivoting moving structure within the probe. The mirrors focus the beams
back onto two position sensitive devices (PSDs) which provide signal outputs in the three probe axes: P, Q, R (converted into X, Y, Z signals by
the calibration routine).
Unlike the SP25M, the RSP3's probe and module elements are built as one.
System components overview
RSP3-1 / 2 / 3 / 4
The RSP3-1 / 2 / 3 / 4 range of probes provide REVO with 3D-scanning (X, Y, Z) touch-trigger and crank stylus capabilities.
RSP3-6
The RSP3-6 probe provides REVO with enhanced capability for carrying long cranked and straight styli. RSP3-6 can be used for both 3D
touch-trigger and 2D scanning applications.
RSH3-1 / 2 / 3 / 4 stylus holders
The RSH3-1 / 2 / 3 / 4 stylus holders are designed to fit with their respective RSP3 probe. They enable accurate scanning measurements with
effective stylus lengths ranging from 20 mm - 394 mm.
The RSH3 range of stylus holders replace the SH25 range of stylus holders for use with REVO only. The SH25 range should still be used with
SP25M.

RSP3 cranked stylus carrying capability for typical stylus combinations
Each RSP3 probe has been optimised for maximum flexibility and sensor performance over a specific stylus range and with different crank
carrying capabilities in mind.
Please refer to Renishaw's stylus catalogue for full details of cranked and star stylus configurations that are available. It is recommended that
a 'one piece' star stylus is used wherever possible to help minimise mass. However, greater flexibility is possible by configuring a star centre
together with one or more cranked styli. Users must be sure that the overall mass of the star centre together with its multiple cranked styli

Straight 'down' styli can be added to RSH3-1 / 2 / 3 / 4 stylus holders below the crank centre to continue the projection 'down' from the
stylus holder, providing that the maximum overall stylus length and mass for that stylus holder is not exceeded.

Manually mounting / removing the stylus holders from RSP3 probes
The range of RSH3 stylus holders have a kinematic coupling to the RSP3 probes, which provides a repeatable connection that eliminates the
need for probe requalification after a change. The change can be carried out either manually, or fully automatically by using the FCR25 flexible
change rack (for RSH3-1 / 2 / 3 / 4) or RCP2 (for the RSH3-6 range). The RSH3 stylus holders are designed to only to fit with their respective
scanning module. Incorrect combinations are prevented by the orientation ball in the kinematics.
To manually mount or remove the stylus holder from the RSP3 probe you need to:
1. Align the front sides of the probe with the stylus (making sure that the alignment marks line up).
2. Carefully align the stylus holder and the probe, allowing the magnetic attraction to gently connect the kinematic joints.
3. Gently rotate the stylus holder to ensure correct location.
4. To remove, securely hold the probe, gently tilt the stylus holder to break the kinematic joints.
The REVO probe change system is designed to allow automatic REVO probe and stylus holder changing on a CMM. The primary
purpose of the system is to improve flexibility with the ability to use and store longer styli and large star stylus configurations.
For optimum metrology, REVO probes and stylus holders should be changed automatically using REVO change ports (RCP TC-2,
RCP TC-3 and RCP2) and a flexible change rack (FCR25). These ports are mounted on the modular rack system (MRS2).

Manually mounting / removing the probes from REVO
To manually mount or remove the probe from the REVO head you need to:
1. Align the front sides of the head with the probe (look at the "Renishaw" engraving on the side of probe or alignment marks as applicable).
2. Carefully align the probe to the head, allowing the magnetic attraction to gently connect the kinematic joints.
3. Gently rotate the probe to ensure correct location.
4. To remove, securely hold the probe and gently tilt to break the kinematic joints.

Manually mounting / removing styli from stylus holders
To manually mount or remove the stylus from a stylus holder:
1. The stylus holder must be removed from the module before mounting / removing a stylus.
2. Always stay within the recommended stylus capability range (see RSP3 stylus carrying capability guidelines).
3. Avoid touching the joint face on the stylus holder, as it may become dirty or contaminated.
4. Always use the correct stylus tools to tighten the threaded joints between the stylus and the stylus holder, thus avoiding excess torque
(causing the tool to bend).
5. To remove a stylus, reverse the above procedure.
NOTE: If a spare stylus removal tool is needed please order Renishaw part A-5000-7835 (the set comprises two S7 stylus tools in a
plastic box).

System calibration
It is absolutely crucial that the probe is precisely calibrated for each measurement procedure before measurement is taken. Renishaw
recommends using a universal calibration tower (Renishaw part number A-3060-4590) to ensure best metrology performance with the RSP3
range of scanning probes.
The position of the individual ball styli and their diameters should be established using the probe calibration programme recommended by
the machine manufacturer (see the manufacturer's manual). Each RSP3 probe configuration should initially be calibrated and A0, B0 before
the probe can be calibrated in the required head orientations.
WARNING: It is important, when calibrating the RSP3 probe, that the probe is able to access the full circumference of the
calibration sphere perpendicular to the direction of the stylus. Sub optimal performance is achieved when a probe is unable to scan
the full circumference of the calibration sphere. For instance, to calibrate a probe at both A0, B0 and A90, B0, the calibration sphere
should be mounted with a stalk at 45° to the bed of the CMM.

Calibration with universal calibration tower
The universal calibration tower enables calibration of RSP2 and RSP3 probes on a common artefact. The tower is compatible with the REVO
Ø45 mm datum ball for RSP2 calibration, and up to four standard Ø25 mm datum balls for RSP3 calibration. Twelve separate mounting
positions are available, three at each compass point, that allow datum balls to be attached at either +45°, 0° or ‐45°.
Periodic requalification should be performed under the following circumstances:
CMM supplier's recommendations, particularly in respect to temperature changes
At the start of the working day or a shift
After accidental collision
When new probe / stylus configurations are introduced
If the initial state is unknown or uncertain
