Abstract

In this paper, the roughness of the surface produced by symmetrical face milling is examined. During the research work, the effect of the use of a round milling insert on the surface topography was studied at different cutting speeds. 2D and 3D surface roughness measurements were carried out in three measurement planes parallel to the feed direction, one of them being the plane of symmetry and the other two planes being at the same distance from it, in both sides. From the analysis of results, it was found that surface roughness decreases significantly for cutting speed values over 100 m/min and then its variation is minimal. Furthermore, higher values of surface roughness are observed in the symmetric plane than the other parallel planes and almost in every case, surface roughness was found to be larger on the entry side plane than the exit side plane.
