If you look at machined parts, you will notice that their surfaces embody a complex shape made of a series of peaks and troughs of varying heights, depths, and spacings. Surface roughness is defined as the shorter frequency of real surfaces relative to the troughs.

1 surface roughness_Surface Finish Charts - LJ StarMeasured values expressed as (RMS) root mean square will read approximately eleven percent higher than values expressed in Ra. (Microinches x 1.11 = RMS). For surface roughness measurements, BBS-Systems utilizes a surface measurement instrument. Surface finish can then be described by using the roughness average (Ra) parameter.
1 surface roughness_Surface roughness | RevolvySurface finish, also known as surface texture or surface topography, is the nature of a surface as defined by the three characteristics of lay, surface roughness, and waviness.[1] It comprises the small, local deviations of a surface from the perfectly flat ideal (a true plane).
1 surface roughness_[PDF]B46.1 Intro Webinar - ASMEto specify both surface roughness and waviness. On all surface texture specifications as of January 1997, c and s must be stated . When c and s are not specified, guidelines are given in section 3.3.20.1 and 3.3.20.2 of ASME B46.1 – 2009 for the metrologist to establish c and s.

The roughness filter cutoff length should be chosen by the designer in light of the Intended function of the surface.
1 surface roughness_[PDF]DEVELOPMENT OF SURFACE ROUGHNESS …As surface roughness increases, subject ratings of the surface decreases. To calculate roughness, a profile of the surface with a resolution of 1 mm should be used. The profile should be filtered with a “wheelpath” algorithm with a 2.5 in diameter wheel.
