­MAG Cincinnati­'s E Mill is a solution for the machining of long, small-cross-section parts used in aerospace, const­ruction, shipbuilding, and wind power. It is suited for titanium, aluminum, and composite work on stringers, spars, beams, and similar parts. The system performs contour machining, routing, drilling, and tapping to produce finished, complex, 3-D-geometry parts up to 12 m (39.4 ft) long in a single setup, reducing processing costs compared to vertical-platform machines. The system combines a 500-mm three-axis horizontal machining center with headstock and tailstock adapted from horizontal lathes to provide fourth and fifth axes of motion. The part manipulation system allows A-axis programmable rotation and 360° infinite positioning, while supplying V-axis linear travel for pull-through part feed. The machine includes a choice of 16,000 or 24,000 rpm HSK63A spindle. A drum-style automatic tool changer accommodates 12 tools up to 8 kg (17.6 lb) in weight, 200 mm (7.9 in) in length, and 125 mm (4.9 in) in diameter.

Researchers from Purdue University are studying the fundamental mechanisms behind a method that uses electrical fields to enhance ceramics-sintering processing, which could aid R&D of rechargeable lithium-ion batteries and fuel cells. The research also could shed light on a phenomenon called electromigration, which can affect the performance of electronic devices.
The fusing of emerging technologies from the aerospace materials sector and biological sciences are now, for the first time, heading toward the prospect of growing parts, systems, and, ultimately, perhaps whole aircraft.
France's Dassault Aviation and India's Reliance Group announced in late September 2016 the creation of a joint venture (JV) in India called Dassault Reliance Aerospace. With this announcement came news that the Dassault Reliance Aerospace JV will be a key player in the execution of offset obligations as a part of the 36 Rafale fighter jet purchase agreement that was signed between France and India on September 23, 2016 and is valued at around €7.87 billion, or about Rs. 59,000 crore.
One of the biggest issues in bringing forward new designs is the length of time that it takes to agree to a new specification, research and evaluate the alternative features and configurations, and then embark on a development program that will take the design to flight testing and ultimately operational service.
