“…Sources of AE are numerous and include deformation, fracture, or crack initiation and propagation, which made and still make the observation of AE a useful tool for machine and structure fault detection intended to enhance operation and to avoid unpredictable failures [3][4][5][6]. Subsequently, the evaluation of AE has been increasingly applied in tribological processes such as investigations of friction and wear processes as well as cavitation phenomena [1,7,8].…”

The acquisition and evaluation of acoustic emissions (AE) in tribology have proven to be a meaningful tool for condition monitoring and offer possibilities to deepen the understanding of tribological processes. The authors used this technology with the aim of expanding existing test methodologies towards increased visualization capability of tribological processes and investigated the correlation between tribological processes and acoustic emissions on a Ring-on-Disc and a close-to-component journal bearing test setting. The results of this study include the description of friction as well as wear processes and prove the usability of several AE evaluation parameters whereby a close correlation between AE and tribological processes can be shown. Consequently, it was possible to expand the visualization and evaluation capabilities of the test settings offering additional insights by making use of AE.

“…Acoustic Emission (AE) Analysis turned out to be of advantage for our needs and have been used for similar purposes, like condition monitoring of hydrodynamic journal bearings [2,3,9]. Due to this fact, we accomplished ground experiments with SAE-Sensors attached to the lathe tool.…”

Manufacturing of mechanical components with a large lot size is usually an automated process. The knowledge of the in situ condition of the tool can help to tailor its exchange cycles in order to reduce costs by using it to its full capacity, without compromising workpiece quality. We aim to monitor the condition of a lathe's tool cutting tip by use of acoustic emission (AE) technology in order to increase its service life. Unlike previous research approaches that verified the potential of AE to monitor tool wear, we concentrate on identifying and overcoming application challenges of automated tool wear control that impede a broad and economic use of tool condition monitoring (TCM) in industry.
