System description
RVP is a non-contact vision measurement probe for use with the REVO-2 5-axis measurement system on co-ordinate measuring machines.
RVP increases the multi-sensor capability of REVO-2 by adding non-contact inspection to the existing touch-trigger, high-speed tactile
scanning and surface finish capability of the system.
The RVP system comprises a probe and a range of modules that are automatically interchangeable with all other probe options available for
REVO. This flexibility means that the optimum tool can be selected to inspect a wide range of features, all on one CMM platform.
The RVP system is managed by the same I++ DME compliant interface as REVO-2 and full user functionality is provided by Renishaw's
MODUS metrology software. New MODUS vision software capability includes RVP configuration, image processing with application specific
options and automatic image storage for review and further analysis.

Design principles of the RVP system
The RVP system uses an industry standard CMOS image sensor to capture and then detect the position of features using the contrast between
light and dark areas of the image. Data points are projected on to the location where the image contrast changes from light to dark. A detailed
calibration model of the lens system transforms the co-ordinates of the projected point on the image to real-world, three dimensional coordinates on the part.

RVP probe
RVP is the probe component of the system that houses the sensor and digital signal processor. There are currently two vision modules that
attach to the probe body that enable the inspection of a range of size and shape features.
The RVP component of the system is automatically interchangeable with other probe options using the VPCP heated change port that can be
fixed to the MRS rack system.
Vision modules
The RVP system features two interchangeable vision modules (VM10 and VM11) which are both tailored to provide inspection capability for
different applications. The vision modules attach to the probe body using the same style kinematic mount utilised by all the current REVO
probes.
VM10 has a wider field of view allowing larger features to be inspected and VM11 has a greater stand-off distance which improves
accessibility when inspecting complex parts with hard to reach features.
VA10 calibration artefact
The VA10 is a dedicated calibration artefact used to calibrate the target feature size and stand-off distance of the RVP system when using a
VM10 or VM11. The calibration routine for RVP is fully automated through MODUS and UCCsuite.
VPCP and VMCP change ports
There are two new change ports that can be mounted to an MRS rack system to allow the automated changing of all the RVP probe and
module components.
The VPCP change port is used to change and house the RVP probe body on the machines rack system. The VMCP change port changes and
houses the vision module components of the RVP system. Both rack ports are temperature controlled to ensure that the housed components
are at the correct and most efficient operating temperature.

Installation
Fitting VPCP and VMCP to the MRS / MRS2 rack
The VPCP and VMCP 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 / VMCP.
2. Position the VPCP / VMCP 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 / VMCP and tighten both fixing screws using the hexagonal key supplied.
NOTE: The image above shows the VPCP change port but the procedure is the same for the VMCP change port.
* NOTE: T-nuts must be used with the MRS system. However T-nuts and D-nuts are compatible with the MRS2 system.

Illumination options
RVP lighting techniques
The RVP system has a number of illumination options to ensure that features can be correctly lit allowing accurate and consistent
measurement. Both vision modules have integrated LED illumination to illuminate features that require inspection. The RVP system also uses
a technique which uses back lighting to ensure good contrast of material edges or features.
The lighting technique chosen depends on the type of feature and the material of the part being inspected. RVP system image settings can be
fully customised and adjusted to provide optimum contrast to inspect a range of features.
It is important that the correct exposure is achieved for both front and back lighting applications. The image on the left shows a correctly
exposed back lit hole. The back edge of the hole is sharp and there is good contrast between the material and the white back lit panel.
The image on the right shows a correctly exposed front lit feature. The front edge of the hole is sharp and there is good contrast between the
dark material in the hole and the bright, front lit hole area. When using front lighting, more RVP image settings may need to be adjusted to
get the optimum contrast and to reduce unwanted reflections.
Ambient lighting
Ambient light is an important variable when using the RVP system. For accurate and repeatable inspection, the ambient environment lighting
should be as consistent as possible. Any changes in ambient lighting can potentially affect the system's performance.

Cleaning the RVP system
CAUTION: Always adhere to the safety instructions given on the general safety recommendations and instructions in this
document. Failure to do so could lead to personal injury.
Following the simple procedures given below will prolong the operational life and maintain the high performance of the system. The user
should determine the frequency of inspection and maintenance actions according to the conditions of use.
Kinematic couplings
The kinematic coupling mechanisms incorporated throughout the system have precision ball seating and permanent magnets. It is
recommended that all these features be cleaned before first use, and thereafter at regular intervals.
A cleaning kit for the precision ball seating and permanent magnet is available from your Renishaw supplier (part number A-1085-0016). It
comprises strips of yellow tack material. Use the yellow tack to clean the areas indicated with arrows numbered [1] on the image below.
With clean hands, tear off a small piece, shape into a small ball and press into / onto each of the features in turn, rotating to a fresh piece of
material as you work around.
CAUTION: Ensure no yellow tack debris is left on the surface. The yellow tack should not be used for the electrical contacts [2] or
the optical windows [3].
Electrical contacts
The electrical contacts, indicated with arrows numbered [2] in the image below, should be carefully cleaned with an alcohol-based cleaner (e.g.
IPA) and a lint-free bud. The frequency of cleaning depends on the local environmental conditions, but should be at least every five hundred
changes.

Optical windows
The RVP probe and module optical windows should be cleaned using a proprietary lens cleaning kit to blow or brush debris away from the
window. If debris is still visible, then the optical window should be carefully wiped with a lint free bud and high-purity isopropyl alcohol (IPA).
Extreme care must be taken to avoid damaging the optical coating or scratching the glass. Latex gloves should be worn during the cleaning
procedure and no attempt to directly touch the optical windows should be made.
NOTE: Cleanliness of the optical windows is important to maintain the highest level of performance of the probe and modules. If
any contamination cannot be removed and is resulting in degraded metrology performance, please contact your local Renishaw
office.

Depth of field
The depth of field specifies the range over which a feature can deviate from the nominal stand-off distance and still be measured with
acceptable levels of metrology performance. If features are measured outside the recommended depth of field range, metrology performance
and accuracy will decrease.
