Abstract
. 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.

5 CONCLUSIONS This article presents a study of the roughness of a face milled flat surface with a carbide insert to a C45 steel specimen
The arithmetic mean of the roughness values of the measured points was taken as the base value as the characteristic roughness value
Summary
Face milling is a commonly used machining method worldwide, and because high quality flat surfaces can be produced with high productivity, machined parts are used for a wide range of applications. To expand this and incorporate components, many researchers are conducting research on surface roughness and machining surface topography to better meet operational requirements. The influence of cutting speed vc, feed rate fz, depth of cut ap, and nose radius rε were investigated They found that increasing the feed increased the roughness, since greater forces affect the tool and the grooves are deeper as the distance between the milling tracks increases. The RSM method was used to determine the mean roughness Ra and was validated with experimental results
