Machine tool self-adaptive control method considering flutter suppression

The invention discloses a machine tool self-adaptive control method considering flutter suppression. A spindle motor power signal and a spindle vibration signal in the numerical control machining process are monitored in real time, real-time self-adaptive regulation and control are conducted on the feeding speed and the spindle rotating speed based on the spindle power signal and the spindle vibration signal, and normal machining is not affected in the whole signal collecting process. According to the machine tool self-adaptive control method considering chatter suppression, the machining efficiency can be effectively improved, flutter generated in the machining process can be monitored and suppressed, the machining quality is improved to the maximum extent on the basis that the machiningefficiency is improved, the service life of a cutter and a machine tool can be prolonged, and the production cost is reduced. 本发明公开了一种虑及颤振抑制的机床自适应控制方法，通过对数控加工过程中主轴电机功率信号以及主轴振动信号的实时监测，并基于主轴功率信号和振动信号对进给速度和主轴转速进行实时自适应调控，整个信号采集过程
