Largest laser DED AM cell at GKN Aerospace

GKN Aerospace now has the world’s largest known laser directed energy deposition (DED) additive manufacturing (AM) cell as part of its new Global Technology Centre in Texas. Cell 3 is the next step in pushing the boundaries of large-scale additive manufacturing of titanium aircraft structures through the process of laser metal deposition (LMD) with wire.

Shawn Black, GKN Aerospace’s president of defence, says: “Cell 3 will create opportunities to deliver a whole new level of additively manufactured titanium components to the sizes needed for safety-critical air and space structures. The technology is a game-changer and has shown its proficiencies in producing components faster and with significantly reduced lead times.”

Emag building Mexico plant

The symbolic ground-breaking ceremony recently took place for the new plant of machine tool builder Emag Group at the San Isidro Business Park in Querétaro, Mexico, marking the start of an ambitious investment programme in the region. Taking shape on a total area of 2880 sq m, the production area will span 1800 sq m and offer 30 machine assembly stations. In addition to the production hall, the new building includes support space on three levels with a total area of 1200 sq m. For instance, the second floor will house offices for administration, quotation preparation, sales and engineering.

The importance of self-centring work holding

Machinists obviously demand accuracy and repeatability, but according to Mate,these demands also extend to the vice that holds the workpiece. For this reason, Mate workholding functions as a system. A highly accurate and repeatable base needs a highly accurate and repeatable self-centring vice for the system to provide best-in-class operation. Here, Mate reports that its DynoGrip vices shorten set-up time and reduce process variability.

DynoGrip self-centring vices clamp parts to within 15 µm of perfect centre, repeatable to within 10 µm. These results are due in part to Mate manufacturing the lead screw in-house, using tool steel that is properly hardened and coated with titanium carbo-nitride. The screw has a fine 1.5 mm pitch and a trapezoidal thread yielding a strong, steady push.

Perhaps the most important feature is that Mate machines both the right and left sides of the lead screw from the same top dead centre. This process is how the company controls where the lead screw starts and stops. Mate does the same for the internal thread of the pusher to know the top dead centre. Since the company controls every element of the manufacturing process, it eliminates variability and makes it easy to get to the vice to centre accurately and in a repeatable manner.

DynoGrip self-centring vices also have an anti-lift design to counteract natural physicsthat will cause a part to rise up. The pushers and jaws work together to exert a downward force on the workpiece equal to the clamping force. Furthermore, the quick-change jaws feature a serrated tooth geometry which generates a downward force on the workpiece and a deliver superior ‘bite’ into the workpiece.

New Airbus hub for next-generation wings

Airbus is investing further in its UK innovation capabilities with the opening of a new Wing Technology Development Centre (WTDC) at its Filton site that will build and test demonstrators for a range of programmes and research projects. Alongside engine optimisation, making wings longer, leaner and lighter is one of the biggest opportunities to improve fuel efficiency, reduce CO2 and ultimately work towards the aviation industry’s ambition to achieve net-zero carbon emissions by 2050.

Airbus head of Filton site and Wing of Tomorrow Programme Sue Partridge says: “The new WTDC will help us to ground our research in practicality. A key element of how we deliver technology for next-generation wings is through Wing of Tomorrow [WoT], our largest research and technology programme led by the UK team.” The WoT programme allows Airbus to explore new manufacturing and assembly technologies so future generations can continue to benefit from flying.

Mazak hosts Primary STEM Challenge Final

Yamazaki Mazak hosted over 80 primary school students from across Worcestershire as they showcased their skills and ideas in the 2023 Primary STEM Challenge Final. While the judges deliberated, all the students who took part in the final had a guided tour of Mazak’s European Technology Centre, which also included the opportunity to help program some of Mazak’s latest machine tools. Teams from Nunnery Wood Primary School and Eldersfield Lawn CofE Primary School were eventually crowned winners.

Max Jones, people development manager at Yamazaki Mazak UK, says: “Fostering the next generation of engineering talent is central to the Mazak philosophy. While we have multiple entry points for school and university leavers, as well as experienced engineers and career-changers alike, activities such as the Primary STEM Challenge are a brilliant way of enlightening young minds to the rewarding opportunities a career in engineering can deliver.”
