Abstract

Accuracy and surface finish in micro-endmilling are greatly affected by micro-endmill vibration, which is influenced by both tool edge radius and chipload relative to the minimum chip thickness. In this paper, the acoustic emission signal has been evaluated as a measure of tool tip vibration. It has been found that changes in the AErms signal, which accompany changes in axial depth of cut and feedrate, correspond to increases in tool vibration. Further, it was found that the presence of process instability, due to large axial depth of cut or ploughing-dominated cutting, results in a large increase in the AErms signal.
