Acoustic emission (AE) has been studied extensively as a technique for monitoring machining processes. In this study, relationships between the RMS AE signals and the cutting parameters in precision diamond turning are investigated experimentally. To build such experimental relationships, each measured RMS AE signal is seperated into two components, the one associated with the chip formation and the other one resulting from the rubbing friction at the tool flank-workpiece interface. The responses of these components to variations in cutting parameters are then explained. The experimental data suggest that the AE is generated predominantly by the chip formation in diamond turning, whereas the rubbing friction is one of the primary sources of AE in the conventional turning.
