Surface Finish - Destiny Tool

Most surface finish requirements are noted in Ra as opposed to an RMS value. RMS and Ra are based on different methods of calculating the roughness. Both are done with a profilometer, but the profilometer calculates the roughness differently for Ra and RMS. Ra is the arithmetic average of surface heights measured across a surface.
