Article history: The machining processes could induce residual stresses that enhance or impair greatly the performance
Accepted 6 October 2008 of the ponent. Machining residual stresses correlate very closely with the cutting param-
eters and the tool geometries. In this paper, the effect of the tool flank wear on residual stresses profiles
Keywords: in milling of aluminum alloy 7050-T7451 was investigated. In the experiments, the residual stresses on
Residual stresses the surface of the workpiece and in-depth were measured by using X-ray diffraction technique -
Flank wear bination with electro-polishing technique. In order to correlate the residual stresses with the thermal
Cutting force
and mechanical phenomena developed during milling, the ponents of the cutting forces
