Abstract：In view of the problems in the milling process of aero-engine blade, such as tool status is not easy to be observed and tool change depends on experience, a tool condition monitoring system is developed by using the tool status monitoring method based on power information. In the process of machining, the power signal of machine tool spindle is collected by three-phase power sensor in real time, and the signal data is filtered, analyzed and learned off-line, and the power threshold interval is calculated. The power threshold interval is used as the monitoring standard to realize the monitoring of tool machining process and the prediction of tool life. The milling process of aero-engine compressor blade is taken as the research object, and the tool condition monitoring test is carried out. The results show that through the tool condition monitoring method based on power information, the real-time monitoring of the machining condition for aeroengine blade milling tool and the prediction of the remaining life of the tool can be realized.
