Nikon Metrology Feature REVO Enhancements

By DE Editors

Nikon Metrology  CMMs now leverage the productivity gains offered by Renishaws five-axis REVO probe system. REVO is a dynamic probe system designed to maximize CMM throughput by providing improved accuracy, faster measurement and greater flexibility. With an optimum stiffness-to-weight advantage, Nikon’s ceramic CMMs take full advantage of the performance enhancements offered by REVO for automotive powertrain and aerospace engine applications, among many others.

REVO is an infinite-positioning, 2-axis probe head utilizing a beam of laser light directed from the probe body down a hollow carbon fiber stylus to a reflector at the stylus tip. Thanks to this direct measurement of the stylus tip position, REVO delivers consistent accuracy through a range of stylus lengths up to 500mm. By using synchronized head and machine movement when scanning, REVO enables measurement speeds up to 500 mm/s and 4,000 points/second without affecting accuracy. Five-axis motion allows the probe to re-position as the CMM moves to the next feature. Fewer CMM moves, head positions and stylus changes are required to measure the part. REVO typically reduces CMM cycle times by 30 to 80% compared with other tactile probes.

High resolution scanning, typically 6,000 points per revolution in a bore of 100mm, improves the repeatability of size and location tolerances in cylinder block inspection. Stylus lengths up to 500mm provide access to measure deep bores and pockets. By dynamically adapting the probe head position to match the alignment of the physical part, REVO eliminates the errors caused when the shank of the stylus touches the part during measurement.

According to the company, the ceramic technology used in the Nikon Metrology LK V and LK V SL CMM series offers a superior stiffness-to-weight ratio enabling higher scan speeds without compromising accuracy.
