| Abstract: | In this paper,the author introduces a kind of diagnostic method for tool breakage.By testing the on-line signals of sensor in time domain,the threshold value of tool breakage can be calculated by means of dealing with testing data with mathematical statistics.Therefore,the automatic alarm of tool breakage can be realized so as to prevent accidents. |
