WebSurface roughness can be regarded as the quality of a surface of not being smooth and it is hence linked to human (haptic) perception of the surface texture. From a mathematical perspective it is related to the spatial variability structure of surfaces, and inherently it is a multiscale property. Webfor roughness inspection given in Annex A, EN ISO 4288 [5], [6]. Only the upper limit of roughness is usually established – not a lower lim-it. An exception is cylinder bores where oil is retained in the surface profile and a minimum roughness is required. Rz value Rq value An alternative measure of surface roughness is the Rz value. ISO
