The mean roughness depth Rz is the arithmetic mean of the largest individual seam depths of several adjoining individual measuring sections.
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.
The maximum surface roughness Rt is the distance between the highest and the lowest point of the measuring section.
Rq is the root mean square of all ordinate values within the individual measurement distance l. Rq corresponds to the designation RMS (Root Mean Square).
