The invention aims to provide an abnormal diagnosis method and equipment for a milling machine during keyway milling. The method can recognize the ranges of an upper threshold value and a lower threshold value of the milling machine in a "normal" state through collecting ground data during the operation of the milling machine. According to the method, the milling process of a keyway is reasonablydivided into a plurality of stages layer by layer, and diagnosis is carried out on each stage. In the subsequent diagnosis process, when the to-be-detected feature data deviating from the "normal" state is received, an abnormity warning can be triggered. According to the method, the product quality can be effectively improved, out-of-plan shutdown of equipment is avoided, the maintenance cost is reduced, and the economic benefit is improved. 本发明的目的是提供一种铣床在铣削键槽时的异常诊断方法及设备，本发明通过在铣床运行期间收集地数据，可以识别出铣床"正常"状态下的上限阈值和下限阈值的范围。本发明将键槽的铣削过程，按层合理地切分为多个阶段，对每个阶段进行诊断。后续诊断过程中，当收到偏离"正常"状态时待检测特征数据时，可以触发异常警告。本发明可以有效地提高产品质量，避免设备的的计划外停机，降低维
