Based in Crewkerne, Somerset, VES Precision was established in 1991 to provide a range of precision engineering and subcontract machining services to local companies such as Westland Helicopters (now Leonardo Helicopters) and Normalair Garrett (now Honeywell Aerospace), both of which are located in nearby Yeovil.

Recent substantial investments in advanced, high-yield machine tools have enabled VES Precision to significantly increase its output. As this rise in production had started to place a strain on the company’s inspection provision, VES quality assurance manager Steve Trigg recently investigated CNC CMMs.

After evaluating the merits of CMMs from several leading manufacturers, an Axiom Too HS machine was purchased from Aberlink.

“As our new Aberlink CMM is very easy to use, soon after its installation our operators were up and running,” says Trigg.“In addition to the Axiom Too HS’s improved accuracy specification being able to accommodate high-precision parts, the machine’s automated CNC nature and speed of operation has resulted in considerably quicker throughput in our inspection department.

“Not only has the Axiom Too HS satisfied our current inspection requirements, our new CMM’s speed will enable it to handle any foreseeable increases in production,” he adds.“Also, its accuracy specification will enable the inspection of the most demanding of our components now in the future.”

Available in several capacity variants, the Axiom Too HS boasts an aluminium bridge with a very low thermal mass, making it suitable for use ineither controlled environments or within less than perfect shop-floor conditions. For increased accuracy, air bearings of optimised stiffness are employed on all axes, while a granite Y beam allows the preloading of bridge bearings in both directions.

Uxbridge-based Martin Baker is a specialist in aviation ejector seats, making products that have saved more than 7500 lives to date, with 19 pilots saved in 2018 alone.With quality literally a matter of life or death, for the past 25 years the company has been measuring and controlling its seats and critical life-saving components with the help of metrology expert Mitutoyo.

With ejection seats in all areas of aviation from helicopters and light prop aircraft to fighter jets, Martin Baker currently produces more than 40 seats each month plus a complete variety of components for the regulatory maintenance and repair cycle of existing seats in service. Producing everything from spares for seats dating back to 1949 through to more than 700 parts for each Joint Strike Fighter (JSF) seat, Martin Baker has 25,000 live components and beyond 50,000 parts on its inventory list. With components manufactured by 25 CNC machine tools, at the centre of the 800 employee manufacturing site is a four-machine 72 pallet DMG cell that runs 24 hours a day and 364 days a year.

Ensuring that components conform to the exacting standards of Martin Baker, the company has an inspection department with 55 staff that relies heavily on inspection equipment from Mitutoyo. Discussing the relationship with Mitutoyo, inspection manager Darren Smith says: “Martin Baker has had a long association with Mitutoyo, using hand tools like micrometers, calipers and height gauges, as well as CMMs for more than 30 years. As our company has evolved, so has the technology. We now have five Mitutoyo CMMs, three SurfTest machines, a Contracer, two training kits and the Mitutoyo MeasurLink system for SPC.We also have over 300 Mitutoyo handtools and gauges on-site.”

Researchers at the Henry Moseley X-ray Imaging Facility at the University of Manchester are using Nikon Metrology’s programmable Inspect-X software to develop bespoke computed tomography (CT) solutions that integrate third-party analysis software and control external hardware. The 4D (three dimensions plus time) CT laboratory experiments have the potential to open up new avenues in industrial environments.

Parmesh Gajjar is a research associate at the imaging facility who has been discovering the possibilities of the programmable IPC (inter-process communication) interface to Nikon’s X-ray control software and how it can be harnessed to perform temporal (time-related) CT for scientific, non-destructive observation and quantification of processes that change structure over time in 3D. He says: “Nikon Metrology’s programmable CT systems are a gold mine for researchers and manufacturers alike, as it gives users the flexibility to do whatever they choose.”

Andrew Ramsey, a consultant at Nikon Metrology with experience of developing special CT applications in industry adds: “In the aerospace industry for example, when studying accelerated fatigue crack propagation in fan blades, time-lapse CT can be used to replicate years of work in a fraction of the time.”

The fully programmable IPC software interface allows users to write their own code and implement individual functions in Inspect-X. These functions range from simple tasks such as turning the X-rays on and off, to high-level actions like initiating a CT scan with previously stored acquisition parameters, automatically reconstructing a CT volume using stored settings, and running an automatic analysis using stored macros while providing progress feedback throughout – all without further human intervention. The IPC program can create simplified user interfaces for previously cumbersome tasks and acquire data for the non-destructive examination of a 3D sample.

To meet the demands of approximately 300 new product introductions, including niche volume and motorsport supply annually, Grainger & Worrall recently purchased a Creaform HandyScan 700 from Measurement Solutions. Although already equipped with traditional gantry CMMs, CT systems and white light scanners, the increasing complexity and persistence to push the limits of possibility has driven a need for both greater capacity and capability. The requirement to spend time preparing the surfaces of castings with powder spray, which has always been difficult with projected light scanners, steered the company towards purchasing the Creaform HandyScan 700.

Project engineer David Lang, who was integral to the decision-making process, says: “The HandyScan ticks many boxes. Not requiring powder spray is an obvious benefit in terms of time savings, both before and after scanning. We were spending several thousand pounds annually on spray, which is an inefficient and unnecessary cost. In addition, associated costs were being incurred by having to clean the castings after scanning.”

The HandyScan 700 utilises 14 red laser lines, which in combination offer a large field of view and the capability to capture data quickly.

“As we assessed the product further, additional benefits came to the fore,” says Lang. “The ability to scan with a handheld portable solution was significant, while the fact that the HandyScan and all accessories fit into a small carry case means it is quick and simple to take to the shop floor and start inspecting.”

The latest metrology innovations are proving popular at Sussex-based Ate Aerotech, which specialises in aerodynamic test equipment, typically for wind tunnels used in the motorsport and aviation industries.

Before a wind tunnel test is undertaken, it is vital to calibrate the positional accuracy of the system’s various movable elements, which enables the company’s control algorithms to achieve the required intricate and precise profiles. Faced with the need to perform 3D metrology procedures in such a large-scale environment, Ate Aerotech recently searched for a precise, non-contact co-ordinate measuring system that could provide high levels of calibration accuracy, along with ease and speed of use. Having considered several options, Ate purchased a VantageS laser tracker from Faro, which was to be incorporated into one of its systems for a Chinese client.

The laser tracker soon proved its ability to provide the required challenging levels of accuracy over long distances. Ate Aerotech staff perform wind tunnel calibration tasks by plotting the position of each of the system’s moving parts at their start positions. Then, when each element is traversed throughout a predetermined grid pattern, a series of further readings is taken. The precision of the captured data allows micro adjustments to be made so that the maximum accuracy potential of each Ate Aerotech system can be realised.

Many other uses have been found for the laser tracker, so much so that the company has since invested in a further unit for its own use.
