This paper describes the surface roughness parameters evaluation of Inconel 718 (43 HRC) after turning under laser assisted conditions. The experiment was conducted for cemented carbides inserts under various cutting and laser heating parameters. Tesets based on central composite research program allows to describe an interaction between input (cutting speed vc, laser power P, feed f) and output (roughness parameters according to PN-ISO 4288: Ra, Rz, Rt, Rsk, RSm, Rdq) parameters. The results showed that laser power density decrease values of amplitude type of roughness parameters. Such occurrence is not observed for horizonal and hybrid parameters of surface. The function is not described by monotonic projection. Therefore optimization by usability function was performed to observe complex interaction between input and output values. The findings of this work define which one of values from cutting speed, laser power and feed values have crucial impact on surface roughness constitution.
