Each value uses the same individual height measurements of the surfaces peaks and valleys, but uses the measurements in a different formula.ġ. RMS is calculated as the Root Mean Square of a surfaces measured microscopic peaks and valleys. Ra is calculated as the Roughness Average of a surfaces measured microscopic peaks and valleys. Ra and RMS are both representations of surface roughness, but each is calculated differently. Simply average the height across the microscopic peaks and valleys. Ra is the arithmetic average of surface heights measured across a surface. Number controlled turning, boring, planing, drilling, grinding. Machining marks direction blur, but still visible.
