Abstract

This paper mainly discusses the tool condition monitoring based on dynamic sensitivity, and explores a method for characterizing tool condition characterization. Firstly, the sensitive directions and components of different orders low modes were analyzed in the static state. Modal parameters and the dominant mode are also identified. Secondly, dynamic sensitivity analysis of the tool-workpiece system is analyzed by using operational modes. For the dominant mode, the modal sensitivity is high in both static and dynamic state. Although many factors such as boundary condition change a lot in cutting conditions, the modal sensitive parts do not change. It indicates that the modal sensitivity is the basic attribute. Therefore, it is reliable to analyze the dynamic sensitivity of the tool-workpiece system by the amplitude change of the operational modes during the cutting process.
