With regard to technical cleanliness, manufacturing enterprises in the automobile industry are in charge to produce, to assemble and to distribute their units, components and systems under higher standards regarding technical cleanliness. With the developed testing method it is possible to integrate miniaturised Near Infrared (NIR) sensor systems in existing manufacturing processes for in-situ detection of residues of cooling lubricants on metal surfaces. This method allows to determine application-specifically, the necessary initial parameters for a simulation model, which can determine the optical geometric configuration, the minimal detectable thickness of the film, and the quantifiable field before implementation.
