摘要
对切削过程中发出的四种AE信号从时域、频域和时频域进行了分析 ,说明时频分析对提取刀具破损特征量十分有效 ,并给出了特征量提取的方法。
Four types of AE signals emitted from the cutting process are analysed in time domain,frequency domain and time frequency domain. The results show that time frequency analysis is very effective in extracting tool breakage features. The method of feature extraction is presented in this paper.
