TīmeklisOne can infer from examination of the formulas, that a single large peak or flaw within the microscopic surface texture will effect (raise) the RMS value more than the Ra value. The electropolishing process may improve a surface finish by up to 50%. The electropolishing reaction removes material while it improves surface roughness.
