On-Line Energy-Based Milling Chatter Detection

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.

The role of tool geometry in process damped milling [PDF]

, 2010
The complex interaction between machining structural systems and the cutting process results in machining instability, so called chatter. In some milling scenarios, process damping is a useful phenomenon that can be exploited to mitigate chatter and ...

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 ...

Integration of dynamic behaviour variations in the stability lobes method: 3D lobes construction and application to thin-walled structure milling [PDF]

, 2006
Vibratory problems occurring during peripheral milling of thin-walled structures affect the quality of the fin- ished part and, to a lesser extent, the tool life and the spindle life.

Multisensory Chatter Detection in Band Sawing

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 ...
