A Study on the Monitoring of Chatter Vibration Using Pattern Recognition in the Plunge Grinding

원통연삭시 휠속도 변화의 패턴인식을 이용한 채터감시에 관한 연구

Bacause the chatter vibration is a main factor to damage on the quality and integrity, The cure is required peticurity in cykinderical plunge grinding. The chatter vibration relatied with wheel speed, workpiece and infeed rate. Therefore, we expressed more credible normal signal and chatter signal Pattern in accrdiance with wheel speed and acquired RMS signal of the accelerrometer. In thos study, after finding the chatter pattern, we applied two parameters, standard deviation and Kurtosis, to Neural Network.
