The most important pointer in the production of machines and equipment is the surface roughness of the compatible details. The surface roughness type and numerical value substantially impress on the surface contact process, fixes the oil retention and adhesive ability. To define these reasons, we need to research the surface roughness. The resulting information will substantially facilitate to solve a problems of machine building. In modern machine building for defining the surface is not enough to use two dimensional profilograph and arithmetic mean value Ra. For far and wide surface characterization, we need to use three dimensional surface measurement equipment. Using equipment of these type, will give perfect conception about the surface and its characterizing parameters. In this case, Machine Building Technology institute of Riga Technical university obtained the three dimensional surface roughness measurement machine Taylor Hobson Form Talysurf 50 and some surface roughness sample sets. Using this machine we will do researching of the surface roughness samples. The result of researching will be to elaborate the atlas of the surfaces. In the atlas will be summarize researching results of miscellaneous processing surfaces
