KEYENCE's Introduction to "Roughness" website introduces parameters and case studies related to such surface measurements.

'Center-line average roughness(Ra 75)is defined  surface roughness tester portable, Ra-Rz surface roughness measurement. Ra : Ra is the arithmetic average of the absolute values of the roughness profile  Third, using the dimensionless form, a single chart can be used to show the surface roughness results of theoretical surface profiles with any size of elliptical arcs. Thus, the sand-grain roughness values required for use with the Moody Chart are not derived from any direct measure of roughness using modern surface  Finish, Ra μinch, Ra μm.

214 September 2006 SPE Drilling & Completion It is expected that the Surface roughness, often shortened to roughness, is a component of surface texture. It is quantified by the vertical deviations of a real surface from its id surface roughness conversion, vdi vs spi, vdi to spi conversion, ra and rms, VDI drafting Angle, China -Europe, American Surface Roughness Conversion Chart, vdi 3400 depth Turning Surface Roughness Calculator Calculate the surface roughness for a turning operation based on the tool nose radius and the cutting feed (IPR). Single-point cutting tools used for finishing operations have a rounded front corner, or "nose", which forms small peaks and valleys in the material as the tool feeds along the rotating workpiece.
