Surface residual stresses generated by machining remain a key issue for safety components of mechanical systems. Many simulations technics have been proposed. One of the most promising is to use the hybrid approach, which combines experimental characterizations with numerical computations. The hybrid method simulates equivalent thermomechanical loadings onto the machined surface without modeling the chip removal process. After a preliminary validation of this approach during the machining of an austenitic and a martensitic stainless steel, this papers aims at validating its application on a ferritic-perlitic steel 27MnCr5. This will confirm that the model is capable of predicting residual stresses for a wide variety of alloys. (C) 2016 Published by Elsevier B.V.
