Surf's Up: Roughness in Ra?
More web resources useful to understand roller surfaces:
What surface modification processes produce what range of roughnesses?
One answer, courtesy of Precision Devices, Inc web page (a maker of surface roughness measurement equipment).
1. Surface Profile Parameters
Defines Ra and other roughness parameters and show how they are calculated.
2. Drawing Indication of Surface Texture
A table showing the range of roughnesses typically produced by differ processes and how to indicate surfaced on engineering drawings.
