ABSTRACT
Just as medical patients would be less than satisŸed if their doctors needed to open their bodies for routine health checks, the opening of a machine to evaluate if it is performing satisfactorily can o§en be much more harmful than good. Accordingly, it makes sense to use diagnostic techniques to assess the condition of a tribosystem in just the same way as a medical doctor uses symptoms to assess the condition of humans. ˜e purpose of this chapter is to present technologies for machinery diagnosis and suggest how they may be readily applied.
