The research work presented aims to validate the operation of the hydrostatic ball burnishing as a strategy to improve the surface quality of an aeronautical component of Inconel 718, previously shaped by Asymetric Incremetal Sheet Forming (AISF). The combination of both processes, burnishing on AISF, has a very high level of innovation and is a pioneer in its application on an industrial component made of this high performance nickel-chromium alloy. The surface quality of the incrementally shaped component has been studied to subsequently apply a burnishing by means of the hydrostatic ball. The results obtained confirm the feasibility of the proposed strategy, with a reduction in roughness up to 30%, depending on the area treated.Keywords: Asymetric Incremental Sheet Forning (AISF), Hydrostatic Ball Burnishing, Inconel 718, Surface finishing and Roughness.
