Casting specialist opts for HandyScan 700

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.”

GapGun used on F-25 JSF

A presentation on seam validation measurement at this year’s Co-ordinate Metrology Society Conference (CMSC) in Nevada, USA showcased how Lockheed Martin incorporates GapGun – Third Dimension’s best-selling hand-held laser measurement system – into the company’s quality inspection processes deployed on its F-35 Joint Strike Fighter (JSF).

Lockheed Martin explained how seam validation – the process of measuring the gap and mismatch between body panels – has become a networked process whereby seam types can be measured at a faster rate, repeatedly delivering significant improvements in time saving and reducing the risk of human error.

Quick and easy to use, GapGun takes measurements throughout Lockheed’s production line, so problems can be headed off before they arise, thereby accelerating and streamlining the production process.

Using LINK SDK – Lockheed’s customised seam validation management system (SVMS) – check plans can be sent straight to GapGun via the network rather than being manually downloaded. The results are then passed straight back to the SVMS.

Dennis De Roos, chief sales and marketing officer at Third Dimension, says: “We are delighted that Lockheed Martin has chosen GapGun to improve quality control for the F-35 aircraft. GapGun is simple to use and saves manufacturers time and money, while increasing efficiency.”

GapGun is used by manufacturers in the aerospace, automotive and energy industries. The device is sold in 25 countries and has made its developer, UK-based Third Dimension, a two-time winner of the Queen’s Awards for Enterprise.

Winds of change at Ate Aerotech

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.

Walter reports strong UK Helicheck sales

Walter Ewag UK reports another successful year of order intake during 2018, with particular mention for sales of the company’sHelicheck tool measuring machines.According to sales director Neil Whittingham, “while last year’s order book was especially focused on tool grinding and erosion, this year we’ve also seen a shift towards investment in tool measurement from across the Helicheck range, including the top-of-the-range Helicheck 3D”.

With X-, Y- and Z-axis capacities of 270 x 455 x 325 mm, plus an A axis of 360°, the Helicheck 3D utilises a novel method of laser digitising so that items canbe scanned quickly and easily. This capability creates3D model data that can be saved, processed, analysed and measured.

The machine’s 3D Tool Analyser software – specifically developed for the application – can lay horizontal, vertical and freely selectable cutting planes at any position on the 3D model. These planes are automatically analysed and the resulting parameters made available for use.The capability to measure all important tool features is said to be quick and simple with Helicheck 3D, and since measurements are carried out on virtual models, the process can be performed offline.

A software 3D ‘matcher’ enables users to create a colour-coded comparison of two 3D models within the machine’s graphical user interface. After the ‘match’ of both models, the operator instantly receives an evaluation of product quality and any deviations from desired values.

Whittingham adds: “Of course, not all machines ordered in a certain year are delivered during that year, which means we have a healthy outlook as we enter 2019.”

Ford develops automated hot forming

Once it was a technique that helped protect knights in armour from the crashing blows of their rivals. Now, Ford is applying a cutting-edge version of the same technology to help make its cars safer than ever. The first fully automated hot-forming process shapes and cuts parts of the all-new Ford Focus – which are integral to protecting drivers and passengers – using large furnaces, robots and 3000°C lasers.

The hot-forming line – fully integrated within the company’s Saarlouis vehicle assembly plant in Germany – was built as part of a recent €600m investment in the facility. Hot-formed steel pieces are subjected to temperatures of up to 930°C, unloaded by robots into a hydraulic press that has a closing force up to 1150 tonnes, and then shaped and cooled in just three seconds. The boron steel is so strong by this point that a laser beam hotter than lava is used to precision-cut each piece into its final shape.
