Roughness affects various part characteristics, including the amount of wear, the ability to form a seal when the part makes contact with something, and the ability to coat the part. KEYENCE's Introduction to "Roughness" website introduces parameters and case studies related to such surface measurements.

Similarly in atomic force microscopes, depending on the different modes, there is a parameter that serves as the setpoint. For example, in static mode (contact mode) the feedback parameter is cantilever deflection, while in the most common form of tapping mode, the cantilever oscillation amplitude is the feedback parameter. The instrument is ...

Atomic force microscopy (AFM) is a powerful technique that enables the imaging of almost any type of surface, including polymers, ceramics, composites, glass and biological samples. AFM is used to measure and localize many different forces, including adhesion strength, magnetic forces and mechanical properties.

In manipulation, the forces between tip and sample can also be used to change the properties of the sample in a controlled way, for example, atomic manipulation, scanning probe lithography and local stimulation of cells.
