Abstract: A system and a method for detecting tool status of a machine tool equipped with a controller and cutting tools are provided. The method includes the steps of: receiving a plurality of manufacturing signals; processing data from the manufacturing signals to organized information; selecting target features characterizing less noise, high effectiveness, and low multicollinearity from the organized information; fitting a classification model using tool status information with the organized information and the target features; obtaining tool status levels by using the classification model; and outputting tool treatments corresponding to the tool status levels.
