System quantity/quality assessment — the quasi-steady state monitoring of inputs and outputsmachine suddenly to stop functioning. The approach depends on seeking out and observing the symptoms of discrete faults, which may be expected to develop slowly before accelerating to failure; for example: bearings starting to break up, seal leakage, or fatigue cracks which, if undetected, could res

As a consequence, it is important to explain initially what input/output monitoring is in a general sense, and subsequently in the context of the techniques to be explained in later sections of this chapter. Thus, input/output monitoring may be defined

System monitoring and the use of modelsy be compared. When this ‘check-out’ indicates a divergence from normal operation then a diagnostic routine is invoked. The template may be described as a ‘model’ of the manufacturing system. One can classify these models into two broad types, statistical and time-based. The statistical models can b

Common vibration monitoring techniques operated until they fail, without any maintenance being conducted upon them until the failure occurs. Scheduled maintenance, on the other hand, is concerned with interrupting production on machines at regular intervals for maintenance. This is done in order to reduce the number of unplanned stoppag

Commercial applications of vibration monitoringuch efficiency, their operations and maintenance philosophies must be cost-effective, and thereby permit the company to achieve maximum profitability. The maintenance of large industrial assets has previously been considered as a fixed overhead by the majority of companies, and as a consequence, car
