This paper deals with an additional option of online-monitoring for abrasive waterjet cutting processes. In the presented studies the carbon fibre reinforced polymer M21/T800S was machined under variation of different machining parameters, which are the machining pressure, the amount of abrasive and the feed speed. In a series of experiments linear cuts were monitored by measuring structure-borne sounds caused by the machining process. For the evaluation of the acoustic emission signals a burst analysis was applied using the acoustic emission sensor iMPact XS of the company iNDtact. In the investigations the count of bursts and the energy of the bursts are correlated with the machining process or rather the cutting quality. The results show that the machining parameters affect the acoustic emission signals significantly in a characteristic way. In conclusion the emitted bursts allow an evaluation of the cutting quality during the machining process.
