Surface finish measurement is now an exact science for everyday use

Defines the list of parameters which can be derived from roughness profiles and the unfiltered profiles. Describes instruments capable of measuring these parameters and their use as part of a Statistical Process Control System to form an essential part of SPC procedures. Details the fixing and power source options that allow detectors to be either portable or mounted close to the production line, including an air suspension vibration isolator to eliminate the effects of vibrations which could otherwise prove troublesome in workshop use.
