WebRa is the arithmetic average of surface heights measured across a surface. Simply average the height across the microscopic peaks and valleys. Ra and RMS are both representations of surface roughness, but each is calculated differently. Ra is calculated as the Roughness Average of a surfaces measured microscopic peaks and valleys. WebIn measurement of roughness, surface profiles are taken with a lateral sampling interval of 0.125 m, typically over an evaluation length of 4 mm. Three parameters of the instrumentation are important in the specification of roughness measurements.
