Abstract

The regeneration effect is a major mechanism for self-excited chatter vibration in cutting. It is known that the regeneration effect could be suppressed by using variable helix end mills. In this study, we discuss the effect of variable helix end mills on regeneration from the viewpoint of feedback stability. The regeneration effect with the consideration of variable helix is calculated and analyzed in cutting test.
