AB  - By achieving the accuracy and roughness requirements imposed on the connecting surfaces of machine components -the topography created during machining - it is guaranteed to meet the operational requirements. We cannot ignore the fact that if connected milled plane surfaces move in different directions relative to each other during operation, there may be different contact conditions caused by the unevenness of the topography. The direction-dependent roughness irregularities and functional characteristics of the topography are not sufficiently explored, thus in this work we examine the roughness and its deviations by assuming displacements in different directions compared to the feed motion during operation. The inhomogeneity of the topography is analyzed with a symmetrical milling setup on a face-milled surface, with profiles measured in plane sections parallel to and in 8 other different directions from the feed. The degree and distribution of deviations of the recorded roughness profiles, the selected amplitude and functional roughness values are examined at several points of the measurement planes.
