Surfaces and Parameters
A surface can be characterized by many, many parameters. In fact, it is easier to define a new parameter than to come with a thorough analysis of the usefulness of the already existing parameters. Parameters are defined in many ISO standards (see references). They can be separated in 2-D and 3-D parameters, and further separation is possible in amplitude parameters, spacing parameters, hybrid parameters, parameters derived from integrated probability density curves, and topological parameters.
This section is confined to surface texture characterizing parameters. For the defined R (roughness) parameters, there are equivalent P (unfiltered profile) parameters and W (waviness) parameters that are defined for longer wavelength limits.
Roughness parameters naturally depend on the length scale where...
