Abstract

A chatter mark is formed on machined surfaces when regenerative chatter vibration occurs during end milling. We proposed a method for inverse analysis of chatter vibration information (frequency and phase shift of the regenerative effect) based on two-dimensional discrete Fourier transform of the chatter mark. Here, the proposed method was used to analyze chatter vibration at a higher frequency than in previous research, which occurred at various spindle cutting speeds. The results obtained by the proposed method were compared with those based on tool vibration measured by acceleration sensors. The results confirmed that the proposed method can accurately analyze the vibration information for high-frequency chatter vibration and can clearly capture the variation in vibration information according to the stability lobe diagram.
