Renishaw has assembled the technology and resources to offer CMM users a complete upgrade service, providing a low-risk transition to its Revo five-axis measurement technology.

Users of all brands of CMM can now transform their measurement performance with a switch to Renishaw’s metrology systems.

The company can provide a comprehensive CMM retrofit based around the UCC2 universal CMM controller and its Modus CMM metrology software.

Combined with its range of touch-trigger, scanning and five-axis sensors, as well as recent investments in UKAS-accredited staff and facilities, Renishaw has assembled all the elements to develop a strong CMM retrofit business.

Although Renishaw’s Revo five-axis measuring system has been available via Mitutoyo, Wenzel, Dukin and Metris for some time, until now, users of other machines have been unable to use this technology.

‘We have put in place a rigorous machine survey to assess the mechanical and electrical components of each CMM, and we commit to a level of system performance so the customer knows what he is going to get before we start,’ said Brian Gow, marketing manager for Renishaw’s CMM Products Division.

Renishaw recognises that CMM users will require high levels of machine uptime and so responsive service and knowledgeable support are both vital.

Renishaw offers retrofit customers a flexible range of maintenance contract options, including software maintenance; calibration, preventative maintenance and emergency support visits; out-of-hours support and top-up software training.

Each contract is bespoke, enabling the customer to select the combination of services that suits their needs, with the flexibility to carry over unused days to the next period.

A range of online resources is also available from the company’s website, including searchable help topics, frequently asked questions and answers, a discussion forum, software updates, plus the facility to log help requests.

To meet the installation and support needs of its CMM retrofit customers, Renishaw has been investing in new staff and facilities.

This includes the recent acquisition of Qualis Service , a CMM service firm with field service engineers located throughout Germany.

Sales and applications staff have also been recruited in the US and throughout Europe.

Renishaw has also established a manufacturing cell in its facility at Gloucestershire, UK, that is dedicated to the assembly and testing of retrofit kits.

This facility is being replicated in major Renishaw subsidiary facilities around the world.

Renishaw can now offer state-of-the-art technology in all aspects of a CMM retrofit, including sensors, controller and metrology software.

Its Revo five-axis measuring system offers fast measurement speeds, reduced calibration time, and flexible access to features.

Revo allows CMM users to measure feature form while also increasing measurement throughput and reducing operator intervention.

With programmable stylus and sensor changing, Revo users can automate even the most complex measurement task.

Future Revo sensors, the first of which will enable surface finish measurement on a CMM (available later in 2009), will allow existing quality assurance tasks that are manually intensive to be integrated into a CNC inspection process.

In addition to Revo, retrofit customers can also select from Renishaw’s extensive range of touch-trigger and scanning sensors, mounted to the industry-standard PH10 indexing head.

With automation features such as stylus and sensor changing, these provide capabilities suitable for many measurement applications.

With a common controller and software platform, customers who choose these sensors are offered a route to upgrade to five-axis measurement as their needs change.

Renishaw’s UCC2 universal CMM controller is at the heart of the Renishaw CMM retrofit.

Combined with a Renishaw servo power amplifier, it enables precision control of up to five axes of simultaneous motion on machines of all sizes.

It also provides a single-box interface to all Renishaw sensors and can gather surface data at up to 4,000 points per second.

Machine error mapping is provided in an open format, allowing users to perform their own recalibration, while temperature compensation is also available.

The UCC2 also complies with the I++ DME standard, giving users the freedom to use any metrology software that features an I++ client.

One such software is Renishaw’s Modus package.

With full support for its entire range of sensors, Modus provides a platform for five-axis measurement.

Key features include CAD-driven offline programming with full simulation and collision detection of five-axis moves; native DMIS support; certified mathematical algorithms; text and graphical reporting; and flexible output of results data.
