An online chatter detection and recognition method for camshaft non-circular contour high-speed grinding based on improved LMD and GAPSO-ABC-SVM

[Display omitted] •The local mean decomposition (LMD) algorithm is improved by the mirror extension method, moving average algorithm, and adaptive soft screening stopping criterion.•Considering the influence of the curvature change of the non-circular contour grinding surface on the chatter features...
