Surface finish of additively manufactured Ti6Al4V workpieces after ball end milling

Abstract This work investigates the machinability characteristics of additively manufactured Ti6Al4V titanium alloy workpieces in finishing machining using ball end mills on 45° inclined surfaces. The surface finish results were compared with ones from milling trials wrought samples same cutting conditions. Optical profilometry and scanning electron microscope imaging used to compare different texture quality two alloys, as well chip morphology, aim finding a correlation between obtained at varying parameters peculiar microstructure induced by additive manufacturing process. showed that allowed for better respect one. was attributed interactions mill edge α phase colonies such alloy, which may favor material removal locally lowering resistance cutting.
