Safety
Before unpacking and installing the RFP system, the user should carefully read the safety instructions below and ensure that they are followed
at all times by all operators.
The RFP system should only be used with the REVO-2 head.
Operators must be trained in the use and application of the REVO-2 system and accompanying products, in the context of the machine it is
fitted to, before being allowed to operate that machine.
Permanent magnets are used in some components of the REVO-2 system and associated products. It is important to keep them away from
items which may be affected by magnetic fields, e.g. data storage systems, pacemakers and watches.
RFP1 probe LED emissions
The RFP1 probe incorporates high power LED lights and should not be used in the event of serious damage to any part of the probe. In such
cases immediately disconnect the power source, remove and do not attempt to reuse the parts. Contact your supplier for advice.
CAUTION: This equipment uses LED illumination that may flash at a variable rate. Avoid exposure or seek advice from your
medical practitioner if you are susceptible to photosensitivity or related health effects.

System description
The REVO fringe probe (RFP1) is a non-contact structured light sensor for the REVO®system offering highly accurate measurement of
surface topology on an infinite positioning, 5-axis CMM platform. RFP1 increases the multi-sensor capability of the REVO system, which now
offers interchangeable tactile scanning, touch-trigger, surface finish, non-contact structured light and vision probes.
The RFP system is managed by the same I++ DME compliant interface as REVO-2 and DMIS support is available through MODUS 1.11
onwards or other suitable metrology software which offers use of the RFP system.
RFP system specific software includes RFP Digitiser, an online I++ client that collects data from parts without CAD models as part of a reverse
engineering process and RFP Inspection Planner, a tool for path planning and generating DMIS part programs from CAD.

Operating principle
RFP1 projects a sinusoidal fringe pattern onto the surface of the part and the camera takes images of the pattern deformation caused by the
surface topology.
On a flat plane the pattern will be uniform:
Changes in surface topology cause deformation of the pattern:

The change in fringe intensity at each point is used to calculate the absolute 3D position of that point on the part surface. A patch of XYZ
position data points is returned for each fringe capture with up to 640,000 points in each patch.

RFP1
RFP1 is the probe component of the system and houses the fringe projector, camera and digital signal processor. It is automatically
interchangeable with other probe options using the VPCP heated change port.
FA10 calibration artefact
The FA10 is an optical calibration artefact used to calibrate RFP1. RSP2 is used on this artefact to link RFP1 with other sensors within the same
coordinate reference frame. The RFP1 fringe pattern is calibrated against a ceramic plate with a tight flatness tolerance. The calibration routine
for RFP1 is fully automated through MODUS and UCCsuite.
VPCP
VPCP can be mounted to an MRS2 rack system to house, and allow the automated changing of, RFP1. The rack port is temperature controlled
to ensure that the probe is at the correct operating temperature.
NOTE: Each time the CMM / system is switched on, RFP1 must be left in the VPCP for one hour to reach the correct operating
temperature before first use.

Manually mounting / removing RFP1 from
REVO-2
NOTE: Mounting / removal of RFP1 to / from REVO-2 should be carried out using a VPCP and automatic change cycle. If it is
necessary to manually attach / detach RFP1 use the following procedure.
1. Align the front of the head with the probe (look at the 'Renishaw' engraving on the front of probe or alignment marks as applicable).
2. Carefully slide the RFP1 up, then horizontally forwards onto the REVO-2 head, ensuring the counterweights do not foul the head as they
pass.
3. Carefully align the probe to the head, allowing the magnetic attraction to gently connect the kinematic joints.
4. To detach, securely hold the probe and gently tilt to break the kinematic joints. Removal is the reverse of step 2.

RFP1 calibration
FA10 calibration artefact
Data collected by RFP1 is in the same reference frame as data collected by the REVO-2 tactile probes. The FA10 artefact is used to calibrate
RFP1 and provides the link between RFP1 and the tactile reference frame.
The calibration routines are automatically controlled by UCCsuite and proceed as follows:
Locating the FA10 artefact using RSP2 and providing the tactile data for linking to RFP1
1. Fix the FA10 artefact onto the bed of the CMM as shown at the end of this section ('Fixing FA10 calibration artefact to CMM').
2. Run the routine in UCCsuite to locate the FA10 artefact using a calibrated RSP2 tool:
The software will prompt the user to position the RSP2 above the location peg on the pillar of the FA10 artefact
The remainder of the moves will be performed automatically
Care must be taken to ensure that there is enough space / machine volume around the FA10 artefact to reach all parts of the artefact
3. Points will be taken as follows:
On the location peg to determine height and initial location
On the pillar to determine orientation of the artefact
On the chequerboard target to determine position
Around the circumference of the phase-to-height (P2H) disk to determine position
On the P2H disc to determine plane height and axis
On the focus patch to determine height

Calibrating an RFP1
1. At the start of the qualification process, the RFP1 will move from its current position to the safe position values defined in the FA10
dialogue box.
User must take care to ensure that there is a clear line of sight from the current position to the FA10 safe position before requesting a
qualification
2. Images will be taken on the P2H disk to normalise the illumination levels and set the triangulation spot position.
3. RFP1 will take images of the pillar to determine the properties of the camera lens.
This aligns the RFP1 camera position to the REVO-2 reference frame, providing the link to RSP2 calibration
4. RFP1 will then take images of the P2H ceramic disc surface to calibrate the fringe pattern.
The triangulation spot is also calibrated during this stage
5. A verification routine is performed automatically at the end of a qualification routine.
RFP1 takes images of the pillar at different head angles to verify the lens parameters
Verification of an RFP1
1. At the start of the verification process, the RFP1 will move from its current position to the safe position values defined in the FA10 dialog
box.
User must take care to ensure that there is a clear line of sight from the current position to the FA10 safe position before requesting a
verification
2. RFP1 takes images of the pillar at different head angles to verify the lens parameters.
Using FA10 for vision calibration
FA10 can also be used to calibrate RVP, instead of using the VA11 calibration artefact.

Fixing FA10 calibration artefact to CMM
The FA10 calibration artefact is designed to be fixed securely to the bed of the CMM to allow accurate and repeatable calibration of RFP1. The
diagrams below show how to fix the FA10 to the bed of the CMM.
1. Locate an appropriate threaded hole in the bed of the machine.
2. Position the artefact plate above the threaded hole.
3. Screw the correct cap head bolt through the hole into the threaded hole on the machine. The supplied washer can be used to correctly fit
smaller diameter bolts.
4. Tighten with a hex wrench.
5. Attach the calibration pillar to the kinematic mount. Integral magnets will secure it in place. Polarisation of the magnets will ensure the
pillar is fitted in the correct orientation.

Installation
Fitting VPCP to the MRS / MRS2 rack
The VPCP heated change ports can be fixed to an MRS or MRS2 rack system. It is recommended that they are attached to the MRS / MRS2 rail
using the following procedure, where it is assumed that the MRS / MRS2 rack system is correctly installed.
1. Insert one of the fixing screws through the VPCP.
2. Position the VPCP underneath the rail and locate the respective T-nut within the rail*.
3. Hand tighten the fixing screw into the T-nut and repeat the process for the next fixing screw.
4. Position the VPCP and tighten both fixing screws using the hexagonal key supplied.
* NOTE: T-nuts must be used with the MRS system. However T-nuts and D-nuts are compatible with the MRS2 system.
