Abstract
Nowadays, the industry looks for sustainable processes to ensure a more
environmentally friendly production. For that reason, more and more aeronautical
companies are replacing chemical milling in the manufacture of skin panels and thin
plates components. This is a challenging operation that requires meeting tight
dimensional tolerances and differs from a rigid body machining due to the low stiffness
of the part. In order to fill the gap of literature research on this field, this work proposes
an experimental study of the effect of the depth of cut, the feed rate and the cutting
speed on the quality characteristics of the machined parts and on the cutting forces
produced during the process. Whereas surface roughness values meet the
specifications for all the machining conditions, an appropriate cutting parameters
selection is likely to lead to a reduction of the final thickness deviation by up to 40% and
the average cutting forces by up to a 20%, which consequently eases the ...
