The invention belongs to the technical field of tool real-time wear detection, and discloses a tool wear state real-time evaluation method and system, a storage medium and a terminal. Every five seconds, an acoustic emission sensor mounted at a cutter handle collects an acoustic emission signal of a cutter in the machining process, and after wavelet denoising, the root mean square value in each sampling period is calculated; and as the processing process is carried out, an application matrix contour model carries out data mining on the time series composed of the root mean square values, the abnormal part contained in the time sequence is found, and the purpose of evaluating the wear state of the cutter in real time is achieved. The tool wear state real-time evaluation method and system, the storage medium and the terminal can be applied to the identification of the continuous acoustic emission signal and can achieve the purpose of evaluating the running state of the cutter online. 本发明属于刀具实时磨损检测技术领域，公开了一种刀具磨损
