| Abstract |
This paper looks at the multiple characteristics and investigations of two grinding
anomalies: grinding burn and grinding chatter. A genetic programming (GP) of multiple
classifications was investigated for different machining strategies and associated anomaly
phenomena. Such a GP paradigm could evolve rules to provide the correlation between monitored
signals and grinding phenomena. The investigation also looks at both Short-Time Fourier
Transforms (STFT) and Wavelet Packet Transforms (WPT) to convert the raw acoustic emission
(AE) signal into a time based frequency signal, segmented into different frequency bands. A set of
encouraging results is presented. |
