WebBoth the roughness average Ra and the maximum height of profile Rz were calculated from the profile data. The calculation of Rz can be ambiguous. Rz is presently defined in ISO Standard 4287 (1997) [5] as “the sum of the largest profile peak height Zp and the largest profile valley depth Zv within a sampling length.” WebThe depth of each groove, number of grooves per centimetre (or grooves per inch), and the surface roughness, are defined by published standards. For example, the ASME B16.5 standard specifies serrations of 1/64 inch (0.4 mm) deep with 32 serrations per inch (12.5 serrations per centimetre) for spiral serrated and concentric serrated flange surfaces.

WebRz stands for the mean roughness depth and calculates the average of the maximum peak-to-valley height measurements from five sampling lengths of the surface profile. Unlike Ra, Rz measures the worst-case peak-to-valley height for each sampling length, which provides a more complete picture of the surface roughness.
