GAP « Green Advanced Panel » PROJECT
Clean Technological Alternative to Chemical Machining
|
|
In order to reduce aircraft mass and energy consumption, fuselage panels
have to be machined to reduce their thickness in different specific places of the panel.
Double-curvature panel machining has been performed by chemical machining in heated
weld bath until today.
This technology has diverse negative impacts on environments: water, energy, masking waste, sludge…
The GAP« Green Advanced Panel » objective is to implement a clean technological
alternative to chemical machining.
The MMS Process– Milling Mirror System has been developped by Dufieux Industrie in 2005
as a result of a partnership with AIRBUS. This mechanical machining has substituted for chemical machining
thanks to the mastery of several innovations. With mechanical machining, the only by-products generated are aluminimum chips that are
totally recycled as secondary raw materials.
Since 2006, in 3 shift production conditions 7/7 days, the Perform MMS 8008 machines range
have demonstrated the technical, environmental and economic performances of
the mechanical machining of the specific shape panels used in aeronautics and space industries.
