An adaptive grinding chatter detection method considering the chatter frequency shift characteristic

Mechanical Systems and Signal Processing, 2020
Abstract At present the majority of the research works on machining chatter detection are based on energy level monitoring of certain chatter frequencies which are premised to be invariant. However, chatter frequencies are very complicated with multi-frequency/frequency band, time-variant characteristics and are also affected by many factors in the ...

Development of an intelligent multisensor chatter detection system in milling

Mechanical Systems and Signal Processing, 2009
The development of a chatter detection system based on multiple sensors and suitable for application in industrial conditions was investigated in this paper. The signals obtained from a monitoring system composed of accelerometers mounted on the machine head and an axial force sensor were processed by using advanced signal analysis techniques such as ...

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.

An intelligent sensor for detection of milling chatter

Journal of Intelligent Manufacturing, 1994
In this paper, a new real-time sensor system has been developed to detect chatter in milling operations. In the developed sensor system, a pattern recognition technique based on an unsupervised neural network using the adaptive resonance theory (ART) is adopted for detection of milling chatter.
