Method and device for evaluating health condition of dicing cutter in real time and dicing cutter

The invention relates to a method and device for evaluating the health condition of a dicing cutter in real time and the dicing cutter. The method comprises the steps that first, the real-time rate of change of the cutter pressure value of the dicing cutter is calculated in real time; second, a first length of time with the rate of change during a preset health condition calculation period of zero is calculated; third, the health condition of the slicing cutter is determined according to the ratio of the first length of time to the theoretical length of time, wherein the theoretical length of time is the design length of time of the dicing cutter with the real-time rate of change of the pressure value of the dicing cutter during one pressure value fluctuation period of zero. The method and device can carry out real-time meaningful monitoring and evaluation on the health condition of the dicing cutter, and the dicing quality of the dicing cutter can be ensured. Therefore, the health condition of the dicing cutter can be predicted and monitored in real time, stable operation of the dicing cuter is ensured, the production cost is reduced, and economic benefits are increased.
