摘要
The most significant characteristic in frequency domain during cutting chatter occurring process is the steep rise of the vibration energy in certain narrow frequency band containing the chatter frequency. In accordance with the frequency band-energy principle, a reliable criterion for chatter judgement is proposed and the in-process detection of cutting chatter is realized by the use of microcomputer. This method has the advantages of rapidity, high sensitivity, accuracy and high resistance to interference. Some concrete measures taken in practical applications are also discussed.
