Rz (Average Maximum Height)

Rz, or Average Maximum Height, is a surface roughness parameter that measures the vertical variations on a material's surface over a specified length. It focuses on the average of the five highest peaks and the five deepest valleys within those segments, providing an indication of the surface's roughness and texture. Essentially, Rz helps quantify how bumpy or smooth a surface appears, which is important for assessing its functionality, wear resistance, or how well it can bond with other materials. It offers a more detailed insight into surface irregularities compared to average roughness measures.
