The wing ribs are structural components within the wing. Along with the longerons, they form the frame for the wing skin. Each aerofoil rib has different dimensions and is constructed differently. Aluminium and CFRP are the most frequently used materials for these fairly unstable and sensitive components.
Our customers rely on HPC and HSM aluminium machining using insert mills, solid carbide mills and, occasionally, PCD mills. CFRP materials are machined using PCD-coated mills or PCD tools. During machining, due to the instability of the material, maximum process reliability is necessary for contour and pocket milling.
