Quicker, faster, better calibration and machine calibration in the workplace from NPL

15.04.2008
The National Physical Laboratory (NPL) is launching a revolutionary new measurement system that will bring laboratory level standards to the shop floor. The technology enables significantly improved calibration times and thereby, minimises machine downtime for industries across the manufacturing sector.

NPL and its partner ETALON are unveiling Laser TRACER at MACH 2008 in Birmingham. This is a high-speed, ultra precise, mobile system for the calibration and verification of coordinate-measuring machines (CMM), CNC machine tools, and other leading-edge measurement applications.

Laser TRACER relies on a highly stable laser source and an NPL patented internal design that is mechanically and thermally decoupled from the tracking mechanism, providing the ultimate in stability and accuracy of measurement.

Like conventional laser techniques, laser tracer locks out the machine during tool or CMM probe. It uses the laser to track a reflector mounted on the machine during tool or CMM probe. The system automatically drives the tool during the measurement cycle for the machine test and then guides the user in simple steps through the testing process. The internal algorithm ensures self-calibration of the system during the test and enables all machine error contribution with unprecedented precision.

Measurement routines can be performed without the need for highly skilled technicians and are significantly quicker than existing traditional methods. Uncertainties of measurements are generated in real time with a comprehensive test report or UKAS calibration certificate produced at the point of measurement.

Automatic correction of stored error-maps is also available for many machine types with new machines being supported every month and the measurement procedure is designed to meet the requirements of the emerging standard ISO10360-2.

David Lowther, Laser TRACER Product Manager, said:

“With the Laser TRACER NPL is bringing cutting edge measurement standards only ever seen before in National Standards Laboratories direct to the customer in their place of work. Machines can now be calibrated in less than three hours, rather than the current time of up to 2 days, and with greatly improved accuracy that will ultimately save time and increase productivity for businesses. NPL can also provide complementary consultancy and support, on site, to diagnose and solve production critical measurement problems for companies. “

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
