Cutter state monitoring method, device, computer equipment and system

The invention provides a cutter state monitoring method and device, computer equipment and a system, and relates to the technical field of computers. The method comprises the following steps: acquiring a plurality of vibration signals of a cutter in a preset time period, and performing various analysis processing on the plurality of vibration signals to obtain multi-dimensional wear characteristics of the cutter; and a preset trained tool state monitoring model is adopted to process the multi-dimensional wear characteristics, the wear state of the tool is determined, and the tool state monitoring model is obtained by training the multi-dimensional sample wear characteristics and the sample wear state corresponding to the sample vibration signals in a preset mode. The tool breaking risk of the tool can be found in time, the operation safety is guaranteed, and the production efficiency is improved. 本申请提供一种刀具状态监测方法、装置、计算机设备及系统，涉及计算机技术领域。该方法包括：获取刀具在预设时间段内的多个振动信号，对多个振动信号进行多种分析处理，得到刀具的多维磨损特征；采用预设训练的刀具状态监测模型，对多维磨损特征
