| Abstract: | To analyze the tool wear status during low frequency vibration assisted drilling of CFRP/TC4 laminated material,a research on the wear status of drilling tools based on cutting force signals was carried out.The cutting force signals of the low frequency vibration assisted drilling of the CFRP/TC4 laminated material were collected to be analyzed in time domain and frequency domain and the relationship between each signal feature and tool wear status was discussed.The reserch results show that the mean value,standard deviation,root mean square and kurtosis coefficient of the axial force signals,during the low frequency vibration assisted drilling of CFRP/TC4 laminated material,are closely related to the tool wear status.The frequency of the axial force signals is mainly concentrated on 0 Hz,spindle rotation frequency at 33 Hz and vibration tool holder vibration frequency at 38 Hz,and the frequency distribution will not change with tool wear. |
