摘要

数控铣床的振动控制系统采用振动信号、主轴电机功率和主轴转速信号。得到了振动信号的时频域特征规律。利用振动信号的均方根、功率谱密度和主轴电机功率对数控机床的切削参数进行调节。控制信号可以控制主轴和联轴器的转速。该系统提高了数控机床的振动控制能力。

Research in Multiple Factors Vibration Controlling of CNC Milling Machine

Vibration signal, power of spindle motor and spindle speed signal are used in the vibration controlling system of CNC milling machine. The rule of time and frequency domain features of vibration signal is got. Using Root Mean Square, power spectral density of vibration signal and the power of spindle motor, the cutting parameters of CNC machine tool is regulated. The controlling signal can control the rotational speed of the spindle and the federate. With this system, the vibration controlling ability of CNC machine tool is improved.
