In this article, the impact of a cooling lubrication fluid, its delivery phase and location, as well as machining parameters, on residual stresses have been investigated. The workpiece material under observation is Inconel 718. For measuring residual stress profiles, X-ray diffraction technique has been used. Additionally, besides the experimental work, modeling with the finite element method model was implemented and correlated with experimental results. The results show that residual stresses are influenced by the cooling lubrication scenario, even though the machining parameters are kept constant. However, flood and cryogenic machining show more compressive residual stresses than a dry machining case. On the other hand, the results have shown also that machining parameters influence residual stresses, where stresses increase with their increase (vc and f).
