In this scientific work investigation of surface with irregular roughness was made with the aim to check the compliance of the surface roughness model with theory and make evaluation of roughness anisotropy, using surface roughness 3D and 2D parameters. Surface roughness measurement experiments were carried out using the measuring equipment Taylor Hobson Talysurf Intra 50. Analysis of the surface roughness model has shown that roughness ordinate distribution function complies with the normal Gaussian distribution law, which was provided by verification of a root mean square height, kurtosis and skewness of ordinate distribution function. During the roughness anisotropy assessment the problem related to the roughness spacing parameters RSm1 and RSm2 was identified. The analysis showed that the values of the spacing parameter RSm2 (in direction parallel to treatment traces) are not reliable, what can be explained by divergence of surface mean plane and mean line of individual profiles, therefore determination of the surface roughness anisotropy coefficient c will not be correct. In this work it was offered to use the surface texture parameter Str instead of the anisotropy coefficient c, what was proven experimentally – for different types of surfaces.
