Rz = average roughness
The average roughness Rz is the arithmetic mean of the largest single roughness depths of several adjacent individual measuring sections.
Ra = arithmetic centers roughness
Ra is the generally recognized and internationally applied roughness parameter. It is the arithmetic mean of the absolute values of the profile deviations within the reference line.
The measured value Ra is always smaller than the Rz value determined on the same roughness profile.
