Chatter vibration in milling often results in poor surface finish and rapid tool wear, consequently limiting productivity. It is known that regenerative effect, which causes chatter vibration, can be suppressed by utilizing irregular pitch cutters. In order to attain robust regeneration suppression for arbitrary chatter frequency, the authors have proposed a novel design theory of irregular pitch cutters. The fundamental mechanism of it is the simultaneous suppression of multi-mode regenerations. In the present study, the effect on chatter suppression has been verified through a series of end milling experiment. Analytical and experimental results indicated that the chatter stability is effectively increased by utilizing the irregular pitch cutter designed by the proposed theory.
