At each machined sample, the climb and conventional cutting zones were evaluated and compared. This paper includes a comprehensive study of thermal and mechanical effects associated with the residual stress introduction. For normal components determination, an optimized micro-indent method was used. Each measurement sequence from this approach was performed using a high accuracy measuring machine and classified according to thermal deviations measured. The residual displacements were determined with an absolute error down to ±300 nm. The normal components analysis allowed to infer the strong influence of the rolling process previous to high-speed milling and besides, the stress levels associated with thermal effects (higher in AA 7075-T6). Finally, the lower residual stress anisotropy degrees in both materials observed in the conventional cutting zone would indicate more homogenous local plastic stretching in this region for all planar directions.application/pdfenginfo:eu-repo/semantics/openAccesshttp://creativecommons.org/licenses/by-nd/4.0/Aluminum alloysAnisotropyHigh-speed millingMicro-indent methodResidual stressesinfo:eu-repo/semantics/articleLos autoresSe autoriza la reproducción para fines educativos, culturales y académicos con la debida mención de la fuente.
