To lower fuel costs and increase operational effectiveness the US Army Tank Automotive Research Development and Engineering Center (TARDEC) launched a campaign in 2014 seeking ways to make combat systems more lightweight.
And although friction stir dovetailing will partially help solve the fuel consumption challenge for the military, it is also available for licensing for other potential applications as well as collaborative research opportunities. Machine manufacturers are integrating smarter, more connected components into their unique design specifications. With the opportunity to increase productivity, safety, and throughput, there is a demand to transition to autonomous machinery across many industries.

Robert Sanchez, Field Application Engineer Manager, TE Connectivity. Save 19%. Once glued, a wood… These compounds grow thick and non-uniformly during the other friction stir techniques, causing joint brittleness and failure.
A December 2nd Machine Design and Electronic Design-hosted live webinar sponsored by TE Connectivity, Date: Wednesday, December 02, 2020 Time: 11:00 AM Eastern Standard Time Sponsor: TE ConnectivityDuration: 30 Minutes. A mechanical interlock is created between the two metals. The new process will be used to make lighter-weight military vehicles that are more agile and fuel efficient. Friction Stir Dovetailing (PNNL) The process – dubbed Friction Stir Dovetailing – was developed by researchers at Pacific Northwest National Laboratory and is described in Scripta Materialia.
To lower fuel costs and increase operational effectiveness while still maintaining the safety of military personnel, the U.S. Army Tank Automotive Research Development and Engineering Center (TARDEC) launched a campaign in 2014 seeking ways to make combat systems — such as tanks, fighting vehicles, and personnel carriers — more lightweight. “We discovered that friction stir dovetailing inhibits intermetallic compound overgrowth because temperature and pressure are much lower than other friction stir approaches.”. In addition to helping to solve the fuel consumption challenge for TARDEC, it is available for licensing for other potential applications as well as collaborative research opportunities with PNNL.
Noted for its resistance to being pulled apart (tensile strength), the dovetail joint is commonly used to join the sides of a drawer to the front. While friction stir scribe solved the challenge of joining thin sheets of aluminum with steel, that technique was found to not scale up to the thick plates of aluminum needed for robust military vehicles. © 2020 Endeavor Business Media, LLC.
: A Gallery. At the same time, the new tool heats the bottom of the dovetail to form a thin metallurgical bond, or … All rights reserved. The new method uses a form of dovetailing. Although friction stir scribe solved the challenge of joining thin sheets of aluminum with steel, it could not be scaled up to handle the thick plates of aluminum (those measured in inches) needed for military vehicles. These previous techniques combined friction stir welding (for join similar metals of differing thickness) and friction stir scribe (which joins thin sheets of significantly different materials, like aluminum and steel). Dovetail joints: These joints have angled sides.
The research team now plans to refine the technique and expand the process for other joint configurations. Compare to. Friction stir dovetailing uses a specially designed tool with a spinning head that generates enough friction to heat and form the aluminum into dovetail that fits into a mechanically cut dovetail groove in a piece of steel.
However, growth of intermetallic compounds – iron aluminide – during the Friction Stir Dovetailing technique is beneficial to the joint because they are so thin – one thousand times thinner than a human hair – which acts as an adhesive without causing embrittlement. Add to Cart + Add to My List. A dovetail joint or simply dovetail is a joinery technique most commonly used in woodworking joinery (carpentry), including furniture, cabinets, log buildings, and traditional timber framing.
Create strong, fine looking dovetail joints with this easy-to-use dovetail jig and your router. “We are constantly looking for innovative multi-material joining methods to help us select the right material for the right purpose in the right location, and friction stir dovetailing offers us precisely such a state-of-the-art method,” said Jason Middleton, TARDEC associate director for Product Lifecycle Engineering. Create quality dovetail joints quickly with this dovetail jig $ 37 99. Threaded commenting powered by interconnect/it code. He has worked closely with many end customers and distribution partners to specify and design-in TE solutions in applications ranging from Appliance, Military, Auto, ICT, Industrial and Medical. Registered Office: Mark Allen Group, St Jude's Church, Dulwich Road, London, SE24 0PB Kevin Brown, Channel Sales Manager, TE Connectivity. Visit the UK’s dedicated jobsite for engineering professionals. In addition to aluminum and steel, other material combinations such as aluminum to copper, aluminum to magnesium, and magnesium to steel can also be joined using friction stir dovetailing. The research team now plans to refine the technique and expand the process for other joint configurations. Chris Zimmerman, Business Development Manager, TE Connectivity.
The researchers are refining the technique and expanding the process for other joint configurations.
A mechanical interlock is created between the two metals.
In addition, the material can stretch to over a half centimeter before the joint break, illustrating five times more ductility than aluminum and steel joined with other friction stir techniques — an attractive feature for military combat vehicles. This indicates the joints have five times the ductility of aluminum and steel joined with other friction stir techniques. Tagged with: joinging technology, Pacific Northwest National Laboratory, Tank Automotive Research Development and Engineering Center (TARDEC). “Intermetallic compounds will form between aluminum and steel during all friction stir techniques as part of the heating process,” said Whalen.
According to the U.S. Government Accountability Office, the military spends several billion dollars each year on fuel consumption, which could be reduced by lightening the weight of ships, aircraft, ground vehicles, and cargo.
Lab testing of joints made by Friction Stir Dovetailing showed that when combining metallurgical bonding with the dovetail configuration, the joint strength is not only superior, but the material can stretch to over a half centimetre before the joint breaks. A recent discovery made by researchers at Pacific Northwest National Laboratory may offer a way to cut some pounds from military gear. Registered in England No. These compounds grow thick and non-uniformly during the other friction stir techniques, causing joint brittleness and failure.
However, because the two pieces slide together easily, they can also come apart quite easily.
