Abstract: The manufacturing chain is usually made of several processes, to create the final surface with regard to design specifications. Manufacturing processes are composed by a complex database, which contains the operating parameters and their settings combinations that impact on the surface parameters. This database may be composed by measured values and it is important to determine the non-measured values through modelling methods to master the final result. This paper aims at establishing a protocol to determine the laser polishing operating parameters for milled and additive lasermanufactured primary surfaces. Several experiments enable to propose models coming from polynomial regression calculus. The proposed models are 88–99% correlated with experiments and the laser polishing parameter enables to bring the initial surface roughness down to 99%. Finally, experiments and models are integrated into a global database to select the laser polishing process parameters regarding both initial milled and additive laser-manufactured surfaces.
