In this paper, the roughness characteristics of the face milled surface were investigated made with a parallelogram insert (κr = 90°) on C45 steel. Changes in surface roughness were analyzed for the specific surface created by the milling movement conditions (rotational main
movement and linear feed motion). The topography was created by a tool moving in the plane of
symmetry of the workpiece, which produced double cutting-edge grooves. We found that the
roughness varies in different parts of the resulting pattern, and we analyzed its nature and the
magnitude of the variance based on the average over the entire surface. Also, in parallel measurements, the Rz parameter was at its maximum in the symmetry plane, and in the
perpendicular direction roughness values are the lowest in the middle and increase with distance.
