Deep Learning for Chatter Detection in Machining
, 2022 Abstract Deep learning unlike classical machine learning methods, automatically extracts features at a higher level and merges feature extraction and classification into a single structure, so it does not require a large number of tests and errors. This work presents a deep learning approach for detecting the phenomenon of chatter in machining.
