Surface Roughness Chart: Understanding Surface Finishes ...
Surface finish refers to the process of altering a metal's surface that involves removing, adding, or reshaping. It is a measure of the complete texture of a product's surface that is defined by three characteristics of surface roughness, waviness, and lay. The surface roughness is the measure of the total spaced irregularities on the surface.

Cp, Cpk, Cm, Cmk, control limits
Cm (capability machine) The Cm index describes machine capability; it is the number of times the spread of the machine fits into the tolerance width. The higher the value of Cm, the better the machine. Example: if Cm = 2.5, the spread fits 2½ times into the tolerance width, while Cm = 1 means that the spread is equal to the tolerance width.
