LK Metrology has expanded its Freedom arm range of 3D articulating-arm metrology systems, or portable measuring arms, with the launch of five ultra-accuracy models in both six-axis and seven-axis variants. The 10 new arms bring the total number of different varieties available from LK to 34.

Called Freedom Ultimate and Freedom Ultimate Scan, the new arms are available with measurement volumes from 2.5 to 4.5 m. Each model complements the comparable size of existing Freedom Classic and higher accuracy Freedom Select products with six axes designed for touch probing, as well as the seven-axis Scan equivalents for multi-sensor metrology, including laser scanning.

The ultra-accuracy arms, which come with a calibration sphere and verification bar carrying ISO 17025 certification, offer increased precision in applications from quality control and on-machine verification, through to reverse engineering, virtual assembly design and 3D modelling. Up to 8% more measuring accuracy is available than the next most precise product range, Select, while compared with the entry-level Classic arms the improvement is up to 43%.

By introducing the extra degree of freedom in all Scan models, Nikon Metrology is providing infinite movement to enable scanning with the company’s ModelMaker H120 laser scanner. All arms are available with a variety of probe kits, styli, mounting rings (including some with a magnetic or vacuum base), tripods, rolling stands and carts with laptop arm.

Carbon-fibre tubular construction ensures stability under challenging operational conditions, while a proprietary counter balance makes manual movements light, promoting ease-of-use even when trying to access awkward areas. Optional Wi-Fi connectivity and battery power allow completely portable wireless measurement.

Following rigorous tests spanning thousands of hours, a new laser radar system for shop-floor quality control has been introduced by the metrology arm of Japanese camera giant Nikon. The APDIS laser radar, an automated, non-contact metrology solution, inspects features at double the speed of the previous version and, according to Nikon, delivers high-accuracy measurements equivalent to those provided by a horizontal-arm CMM.

Nikon Metrology’s laser radar products employ a focused laser beam and heterodyne interferometry to measure range accurately. This configuration produces a sensitive radar that is capable of performing measurements on almost any surface, irrespective of reflection.

Suitable for the repetitive, labour-intensive, complex measuring of objects from a long stand-off distance, and able to access even hard-to-reach areas without the need for photogrammetry targets, retroreflectors, handheld probes or surface preparation, APDIS may be used in numerous manufacturing sectors, including aerospace, automotive, renewable energy, research and indeed any large-scale environment.

A new, high-definition camera coupled with new Nikon confocal optics allow for enhanced viewing of what is being inspected. Better usability results from reducing the unit’s weight by 40% and its size by a quarter, while internal changes and comprehensive testing have further raised the level of reliability.

The APDIS range comprises four models, two of which are the MV430E and MV450E, having a 30 or 50 m radius measuring range respectively. These versions promote the use of APDIS scanners as a non-contact accelerometers by pointing the laser beam at any surface to measure vibrations at up to 2000Hz, which can be useful when assessing installations or equipment.

There are also MV430 and MV450 standard versions without the improvements for applications where top speed and vibration analysis are not required.
