On-Line Energy-Based Milling Chatter Detection [PDF]
Journal of Manufacturing Science and Engineering, 2018 Milling exhibits forced vibrations at tooth passing frequency and its harmonics, as well as chatter vibrations close to one of the natural modes. In addition, there are sidebands, which are spread at the multiples of tooth passing frequency above and below the chatter frequency, and make the robust chatter detection difficult.

Multisensory Chatter Detection in Band Sawing [PDF]
Procedia CIRP, 2013 AbstractWith the development and application of expensive, difficult to cut metals and metal alloys, the minimization of waste material for final operations has, together with the quality of the band sawing process, become more and more important. As the onset of chatter can have a very detrimental effect on the quality of the cut, on the quality of ...

Exploring the Potential of Transfer Learning for Chatter Detection
Procedia Computer Science, 2022 Chatter detection and avoidance are indispensable for many industries that rely on the machining process. The physics-based analytical models and recently successful machine learning methods can provide solutions using data from a unique setting. When the primary conditions of machining alter, new data needs to be collected, and analysis/training ...

Automatic chatter detection in grinding [PDF]
International Journal of Machine Tools and Manufacture, 2003 Two methods for automatic chatter detection in outer diameter plunge feed grinding are proposed. The methods employ entropy and coarse-grained information rate (CIR) as indicators of chatter. Entropy is calculated from a power spectrum, while CIR is calculated directly from fluctuations of a recorded signal.
