Abstract: Acoustic monitoring is a popular tool for determining the working condition of a machine, thus allowing maintenance to be scheduled to minimise any process down time. Acoustic emission is generated by the frictional interaction of contacting asperities between two sliding surfaces in contact, which usually changes as machine components become worn. This paper presents the development of a probing system used to study the number of asperity contacts during sliding friction and give insight into the behaviour of two acoustic parameters, namely acoustic energy and count rate under different loading conditions.
