Abstract

Grinding monitoring enables the online supervision of crucial aspects of the process, such as tool state, surface quality, and dimensional accuracy; and possesses a great advantage over traditional post-process quality control techniques by reducing costs and inspection times. Such an advantage relies on a good interpretation of monitored signals in relation to grinding behaviours. This paper presents an experimental study on acoustic emission (AE) features in abrasive grinding scratch experiments. The acoustic emission signals are analysed in both the time and frequency domains. The results show that the signal feature extraction in the frequency domain gives excellent indication in correlation to the surface creation with different abrasive geometrical characteristics. The AE features in the frequency range between 0 and 200 kHz show good correlation with the characteristics of interaction between abrasive and workpiece in scratching tests and could be an ideal data source for the online monitoring of surface creation in grinding processes.
