Abstract
<p>In end milling, chatter vibration generated during processing becomes a problem in processing accuracy. Chatter vibration is classified into forced chatter and self-excited chatter depending on the cause of the vibration. Especially, stability of self-excited chatter is very important, because it becomes large amplitude vibration if it occurs. Generally, the chatter vibration phenomenon in end milling is modeled as a periodic system with time delay. In our previous study, a numerical method to calculate characteristic exponents of a periodic system with time delay equal to the fundamental period accurately using Fourier series is proposed. In this study, using the proposed method, we verify the effect of anisotropic support on stability. It is shown that anisotropic support has a significant effect on stability and that the degree of stability depends on the relationship between the angle of principal axis of stiffness and the feed direction of machining.</p>
