CNC machining is an exact and accurate manufacturing method that can produce items with tolerances as low as 0.025 mm. But machining processes may leave cut marks on the end product's surface. The surface roughness of a part after machining is rarely random. Instead, steps are taken to ensure that a particular roughness is obtained.

In machining, the interaction of the cutting edges and the micro structure of the material being cut both contribute to the final surface finish. The surface roughness chart demonstrates the visual differences with the same Ra. The roughness of a surface has most commonly been measured by an instrument in which a stylus travels across the surface.
