Aeronautical industrial sector applies currently aluminium alloys in a wide range of its products.
Aerospace precision requirements are highly restricted. Thus, dimensional precision is commonly studied in
the manufacturing processes of aerospace alloys, such aluminium. As a consequence of this, quality finish of
machined aluminium alloys for aeronautical use is deeply analysed, although mainly in terms of dimensional
accuracy. Geometrical precision is usually studied from roughness analysis, which only has into account
microgeometrical aspects. However, macrogeometrical precision is commonly far of the objectives in some of
those analyses. In this work, Parallelism Deviations (PD) of dry turned UNS A92024 (Al-Cu) and UNS A97050
(Al-Zn) samples have been evaluated for different machining conditions (cutting speeds and feeds). A
parametric model for the parallelism deviation as a function of those cutting parameters has been established
from the mathematical treatment of the results obtained. In parallel, a prediction surface PD (f, v) has been
constructed from the 3D interpolation of the set of (f, v, PD) points. This surface allows determining marginal
PD (f) and PD (v) curves for specific v and f values, respectively.
