Different levels of each phenomenon in terms of acoustic emission (AE) correlated to deviation were characterised.
- class="label">•
Physical phenomena using both the time and frequency domain analysis of the AE were gained from the vertical-axis micro milling tests.
- class="label">•
Significant tool wear of micro milling was characterised after and before the onset of tool malfunction.
- class="label">•
Different levels of the characterised phenomena were classified for the prediction of surface quality.

A real-time simulation displaying changing energy patterns as deviation errors increase/decrease was implemented.
