The invention discloses a machining monitoring method and a machining monitoring system for a machine tool. The machining monitoring method and the machining monitoring system are used for machining a workpiece. The processing monitoring method comprises the following steps. Firstly, a vibration signal of a main shaft of the machine tool is detected. Then, a vibration characteristic value of the vibration signal is obtained. Then, whether the vibration characteristic value exceeds a threshold condition or not is judged, and the threshold condition is determined by the training model according to the preset surface quality of the workpiece; if the vibration characteristic value exceeds the threshold condition, the machining parameters of the machine tool are adjusted. 本发明公开一种用于工具机的加工监控方法及加工监控系统，以加工一工件。加工监控方法包括以下步骤。首先，侦测工具机的主轴的振动信号。接着，取得振动信号的振动特征值。之后，判断振动特征值是否超过门槛条件，门槛条件是经过训练模型根据工件的预定表面品质所决定。若振动特征值超过门槛条件，调整工具机的加工参数。
