Faster CMM Inspection and Probe Calibration Times



5-axis COORD 3 Universal CMM

REVO-2 5-axis scanning probe.

Perceptron, Inc. has launched a full range of 5-axis CMMs complete with Renishaw's REVO-2 scanning probe and a fully-integrated UCC CMM controller and MODUS metrology software.

"By combining the metrology stability of the COORD3 Universal CMM with the latest Renishaw REVO-2 5-axis measuring system, CMM dynamic error is minimized for high-speed probe motion since all part feature scanning motion is within the REVO-2 head," said Elliott Mills, CMM Product Sales Director, Perceptron. "The REVO-2 is the only scanning system for CMMs that simultaneously controls the motion of three CMM and two probe head axes, while collecting workpiece data using its range of 3-D tactile probes, surface roughness measurement probe and non-contact vision probe. It uses laser measurement for precise workpiece measurement at extremely high rates of data capture. Scanning rates of 500 mm/sec can now be achieved that are 20 times faster than traditional 3-axis scanning CMMs."

"The Universal CMMs utilize a high-technology alloy moving frame design that provides the benchmark for dynamics and measuring accuracy performance," said a company spokesperson. "This design overcomes the issues associated with operating traditional build CMM structures in the typical, less than perfect CMM operating environments." A CMM thermal compensation system of both machine and part allows the measuring system to automatically and dynamically compensate for changes in the CMM operating environment. This system allows the CMM to perform with stated measuring accuracy between 16 and 26 °C. Gold-plated 0.1 µm measuring scales are free-floating in support tracks, eliminating any CMM structural changes from influencing its measuring accuracy.

"Universal CMMs have a very efficient design in terms of machine simplicity which improves long-term reliability and ultimately cost of CMM ownership," said the spokesperson. "The COORD3 Universal CMMs have an isostatic design for each axis that provides optimum machine geometrical alignment in the construction of the machine, which ultimately benefits the ability to make accurate field calibrations." Universal has a monolithic base-plate, with integral inverted dovetail guide-way, and a 90 mm (3.5 in.) x 90 mm (3.5 in.) Z Ram section providing outstanding metrological performances. Direct axis drives using toothed drive belts provide the vibration-free motion with zero hysteresis.

Universal CMMs can also be equipped with an optional SZP (Safety Zone Protection System) which uses laser scanners to monitor the defined protection zone when the CMM is in high-speed automatic measuring mode. SZP reduces the CMM speed upon infringement of the safety zone by an operator and automatically returns the CMM to its full measuring speed only after the zone infringement has been cleared. The SZP system allows safe use of the CMM in a production, shop-floor and fully-automated applications.

The COORD3 Universal CMM range accommodates part sizes up to 3,000 mm x 1,500 mm x 1,200 mm. COORD3 has already supplied 5-axis CMM's several North American aerospace manufacturing companies.
