Journal ArticleDOI
EEMD-based online milling chatter detection by fractal dimension and power spectral entropy
TL;DR: In this paper, the acceleration signals acquired by sensor were decomposed into a series of intrinsic mode functions (IMFs) by the adaptive analysis method named ensemble empirical mode decomposition (EEMD), and the IMFs which contain the feature information of milling process were selected as the analyzed signals.
Journal ArticleDOI
Early milling chatter identification by improved empirical mode decomposition and multi-indicator synthetic evaluation
TL;DR: The results of milling experiment show that the proposed chatter identification method can recognize early milling chatter effectively and a support vector machine chatter identification model is obtained based on the multi-indicators.
Journal ArticleDOI
Third-order updated full-discretization method for milling stability prediction
TL;DR: Based on third-order Newton interpolation polynomial and direct integration scheme (DIS), a method to generate stability lobe diagram in milling process is proposed and proved to be an accurate and efficient method by the comparison results.
Journal ArticleDOI
Milling stability analysis with considering process damping and mode shapes of in-process thin-walled workpiece
TL;DR: In this paper, the authors considered the process damping determined by the indentation volume between flank face of milling tool and machined surface, and used multi-mode model to describe this behavior.
Journal ArticleDOI
