ABSTRACT:
A data-driven method and system are provided for predicting limit cycle oscillations such as chatter to obtain a classifier signal which, in turn, may be utilized by a control method and system. The method and system utilize algorithms based on random field theory which are applied to "vibration" data to predict when chatter phenomenon may emerge during an ongoing machining process. Using real data from a turning operation on a lathe, the onset of chatter can be predicted so that sufficient time is available to deploy an automatic control strategy such as reduction or random variation of spindle speed to quench the "chatter". The method and system preferably use instantaneous scale of fluctuation.
