Page 2: General Information
Renishaw distributor. Warranty Renishaw plc warrants its equipment for a limited period (as set out in our Standard Terms and Conditions of Sale) provided that it is installed exactly as defined in associated Renishaw documentation. Prior consent must be obtained from Renishaw if non-Renishaw equipment (e.g. interfaces and/or cabling) is to be used or substituted. Failure to comply with this will invalidate the Renishaw warranty. -
Page 3: Care Of Equipment
Renishaw probes and associated systems are precision tools used for obtaining precise measurements and must therefore be treated with care. Changes to Renishaw products Renishaw reserves the right to improve, change or modify its hardware or software without incurring any obligations to make changes to Renishaw equipment previously sold.

Page 9: System Description
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. -
Page 10: Design Principles Of The Rvp System
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 co- ordinates on the part. -

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.

Page 15: Installation
RVP user's guide www.renishaw.com 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. -
Page 16: Fixing Va10 Calibration Artefact To Cmm
Fixing VA10 calibration artefact to CMM The VA10 calibration artefact is designed to be fixed securely to the bed of the CMM to allow accurate and repeatable calibration of the RVP system components. The diagrams below show how to fix the VA10 to the bed of the CMM. -
Page 17: Illumination Options
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. -
Page 18: Cleaning The Rvp System
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. -
Page 19: Optical Windows
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). -
Page 20: Technical Terminology
RVP user's guide www.renishaw.com Technical terminology Stand-off This is the distance between the end of the vision module and the plane at which a feature will be at the sharpest focal distance to provide optimum image capture. Issued 03 2019... -
Page 21: Field Of View
This is the maximum size area that will be projected onto the CMOS sensor when the correct stand-off distance is used. Any feature requiring inspection with RVP must be located within the field of view to allow inspection. Issued 03 2019... -
Page 22: Depth Of Field
RVP user's guide www.renishaw.com 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. - Page 23 Renishaw plc +44 (0)1453 524524 New Mills, Wotton-under-Edge, +44 (0)1453 524901 Gloucestershire, GL12 8JR United Kingdom www.renishaw.com/cmmsupport For worldwide contact details, please visit our main website at www.renishaw.com/contact Issued 03 2019...
