This work is focused on the study of the influence of cutting speed on the induced machining residual stresses of two alloys with widespread use in different components for aero-engines and other industrial applications: austenitic stainless steel (316 L) and titanium alloy (Ti6Al4V). A numerical model based on an Arbitrary Lagrangian Eulerian formulation, validated with experimental results, has been developed. Although the increase of cutting speed raises residual stress, a stabilization of these stresses is observed at high cutting speeds.
