WebSurface Finish Units From RA To RZ. Ra - Average Roughness. Ra is also known as Arithmetic Average (AA) or Center Line Average (CLA). It is the average roughness in the area between the roughness profile and its mean line. Graphically, Ra is the area between the roughness profile and its centerline divided by the evaluation length. WebThe ratio of the two parameters Rz/Ra indicates the type of machining. In case of a ground surface, for instance, this ratio is between 5.8 and 9.5, while in the case of a turned surface, values ...

As an example, on a steel part hardened to 60 HRc, lapped using silicon carbide 500 grit, a pressure of 250 g/cm squared will produce a surface … Surface roughness, often shortened to roughness, is a component of surface finish (surface texture). It is quantified by the deviations in the direction of the normal vector of a real surface from its ideal form. If these deviations are large, the surface is rough; if they are small, the surface is smooth.
