Abstract
In the present study, the critical axial depth of cut at the onset of chatter in the end milling operation determined by Akaike's Information Criterion (AIC) was evaluated. AIC was applied to the time history of tool vibration displacement in order to determine the critical axial depth of cut. The axial depth of cut that makes the value of AIC minimum was defined as the critical axial depth of cut. Comparing with the critical axial depth of cut obtained using the presented AIC method and that by detecting the emergence of the amplitude of the chatter frequency, there are fairly good agreements in both results.
