Chatter stability in robotic milling

Robotics and Computer-Integrated Manufacturing, 2019
Industrial robots are desired to be used in milling light but large aerospace parts due to easier set-up and portability than large machine tools. However, robots are significantly less stiff than the machine tools, hence they cannot be used in all ...

A novel online chatter detection method in milling process based on multiscale entropy and gradient tree boosting

, 2020
In the milling process, chatter, which results in poor surface quality, dimensional errors, reduced cutter and machine life, is one of the main limitations on performance. In this paper, a novel method of online chatter detection for milling processes is

Approximate solutions for chattering control and chattering arc

Acta Astronautica, 2000
Abstract The approximate solution for chattering arc of the first kind chattering control has been studied. Both symmetrical and asymmetrical cases are considered. A practical example analyzed in this paper is the maximum drag reentry flight of a winged space vehicle in the vertical plane. The control variable is the normalized lift coefficient (NLC),

Comparison of classifiers for chatter detection

2013 21st Signal Processing and Communications Applications Conference (SIU), 2013
Unstable machine cutting causes chatter and reduces quality of the production. Therefore it must be detected. Several techniques have been presented for this reason. The aim of this study is to determine the data, features and classifiers which fit on chatter detection.

A Reinforced k-Nearest Neighbors Method With Application to Chatter Identification in High-Speed Milling

IEEE transactions on industrial electronics (1982. Print), 2020
Chatter is a kind of self-excited vibration which will destroy the manufacturing process badly. The detection or identification of chatter is attracting considerable interest for several years.

Two new kurtosis-based similarity evaluation indicators for grinding chatter diagnosis under non-stationary working conditions

, 2021
Chatter is one of the most critical errors in the grinding process, the occurrence of which will directly degrade the ultimate geometrical surface quality of the workpiece.
