Surface roughness is a quantitative calculation of the relative roughness of a linear profile or area, expressed as a single numeric parameter (Ra). A surface consists of three basic components: lay or form (the result of errors when the lathe producing a CNC turned part), waviness (the result of vibrations from inside or outside sources) and roughness (the result of tool geometry, condition, hardness, variation, etc.).
