  10. Surface Finish The Ra parameter measures average roughness. It is not sensitive to occasional spikes and gouges. On the other hand, the Rmax parameter is designed to detect these anomalies. The two surfaces shown here have nearly identical Ra values but very different Rmax values.http://www.mmsonline.com/articles/039903.html
