摘    要: 切削颤振发生过程最显著的频域特征是包含颤振频率的某个窄频段内振动能量的急剧上升。本文根据频段能量原理提出了一种可靠的判据,并利用微型计算机实现了切削颤振的在线监测。该方法具有快速、灵敏、准确和抗干扰能力强等优点。本文还探讨了实际应用中的某些具体措施。

关 键 词:切削颤振  频域特征  判据  在线监测

Abstract:The most significant characteristic in frequency domain during cutting chatter oc-curing 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.
Keywords:cutting chatter  characteristic in frequency domain  criterion  in-process monitoring
