    Surface roughness is usually specified with a "check mark" symbol on a drawing as shown in the figure below. Surface roughness is typically indicated in RMS or microinches (µin) and is located on the left side of the symbol above the check mark. In the example below the roughness value is 32 RMS maximum and 16 RMS minimum.

  • Drawing Indication

    The above symbol indicates that the removal of material by turning is required to achieve an Ra value of 2.2µm and an Rz value of 6.8µm when measured using a 0.8mm cut off and lower cut of value of 0.0025mm with Gaussian filtering. The maximum amount of material removal allowed to achieve the required finish would be 3mm.

  • Surface finish - Wikipedia

    Surface 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. It comprises the small, local deviations of a surface from the perfectly flat ideal (a true plane).. Surface texture is one of the important factors that control friction and transfer layer formation during sliding.
