Abstract:Tool wear state is closely related to the workpiece surface, so tool wear monitoring has an important engineering significance. This paper proposes a tool for wear monitoring means based on EEMD information entropy and PSO-SVM. Firstly, the force signal of the cutting process collected force by the sensor is decomposed by EEMD, and information entropy of the decomposed signal was used as the tool wear feature quantity. Then the PSO-SVM model was used to classify and identify the extracted tool wear feature qua… Show more
