The A380 aircraft is the largest passenger aircraft ever built and an appropriate machine was required to accomplish the fastening of the wing plank to stringer and buttstrap joints. The lower wing panels are curved along the length and move 1.42m out of plane. All previous E4000 machines had clampup heads that would extend and retract whatever distance was required to contact the wing panel. To improve toolpoint alignment, Electroimpact added a Z-axis that moves the yoke in order to reduce the necessary travel envelope of the clamp table axes and to cause them to clamp in the same plane regardless of panel position along the Z-axis.

The Horizontal Automated Wing Drilling Equipment (HAWDE) machine is an enabling technology for automated drilling of large aircraft parts. HAWDE is a five axis drilling machine that operates over the upper and lower surfaces of eight wings, each more than 40 meters long and four stories tall. The machine accesses the entire A380 wing using a combination of elevators and a machine transporter that carries the machine from surface to surface. HAWDE drills holes in spars, butt splices, and rib feet in the wing box final assembly jigs for A380.
