Digital Factory Fast Becoming Reality
One of the world's most advanced computer simulation programs has
been developed by Fairchild Dornier to ensure what it believes will
be the smoothest, most efficient and cost-effective assembly line
in commercial aviation for its 728JET regional airliner.
"This is so advanced that even Airbus has asked us about it
as it prepares to produce the A380," said Rudolf Schmid, head
of digital manufacturing at Fairchild Dornier.
Schmid and his team have taken two years to understand better than
anyone every process that will be involved in assembling the 728JET,
from trucking the center section from Spain to how many engineers
can work simultaneously on assembly jobs in the confines of the
cockpit.
"We know exactly what it takes to do every job, and exactly
how much it costs," Schmid told Show News.
The result is that the factory has already been planned on computer,
not only for layout but for the flow of every part, every tool and
the precise order in which every job must be done. The simulation
was based on an intensive study of assembling the 328JET that resulted
in efficiencies of 20%, and the computer model has in turn been
verified on the 328JET line.
Leaning heavily on automotive manufacturing processes, the simulation
also includes ergonomic factors. The program incorporates "live"
workers on the screen, and ensures they can physically do the job
without banging heads on airframe projections or rapping knuckles
on nearby bolts. So accurate are these representations that Fairchild
Dornier believes it can use them later for training, or for an engineer
at an airline to simulate a repair and watch exactly how it should
be done.
With a brand new, clean-sheet design for the airplane, Fairchild
Dornier had the chance to plan the most modern factory and tooling
for it, rather than adapt existing facilities. The first development
aircraft-which were simulated in mockup form in the computer-are
being built on production tooling designed by the digital manufacturing
team and which is now being installed at the Oberpfaffenhofen plant.
"We are not cutting any corners at all," said Fairchild
Dornier president and CEO Louis Harrington. "This is going
to be one of the most advanced assembly lines in the world."
