摘要

针对航空发动机叶片铣削加工过程中刀具加工状态不易实时监控、更换刀具依赖加工经验等问题，利用基于功率信息的刀具状态监测方法，开发了刀具状态监测系统。通过三相功率传感器实时采集加工过程中机床主轴的功率信号，并对信号数据进行数据筛选、数据分析、离线学习，计算出功率阈值区间，以功率阈值区间为监测标准，实现了对刀具加工过程的监测以及对刀具寿命的预测。以航空发动机压气机叶片的铣削加工过程为研究对象，进行了刀具状态监测试验。结果表明

基于功率信息的刀具状态监测方法可以实现对航空发动机叶片铣刀加工状态的实时监测及对刀具剩余寿命的预测。

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.
