Based on the phase space reconstruction theory and radial basic function network,one step and multi-step predictable method of time series is presented,which is to solve the problems of state of tool wear and breakage of NC machine tools that are used to processing components of a certain type of aircraft engine.Firstly, collect Acoustic emission signal by Acoustic emission sensors,build up a group of time series,obtaine the embedding and delay time.In the reconstructed space,,set up one step and multi-step...
