3D measurement on surface roughness could be used to assess the surface quality but the procedure is time-consuming and the better the equipment and its performances, the smaller the investigated surfaces. There were investigated the spread ranges for several 3D roughness parameters in order to use the information for establishing a less-time consuming, but acceptable set of measurements. The results pointed out there are some parameters with larger spread range (Sa, Sq, St)and others with narrower spread range (Ssk, Sku).
