Modeling, analysis, and removal of chatter marks in flexible turning
International Journal of Advanced Manufacturing Technology, 2017Chatter is a kind of self-excited, unstable vibration in almost all machining processes. Existing studies have been focusing on the pre-chatter stage, developing various techniques to detect, predict, and suppress chatter. In real applications, chatter will inevitably happen under certain cutting conditions, with generating chatter marks on the ...

Detecting chatter mark vibration in rolling mills operating under normal working conditions is difficult. A novel characteristic recognition method of chatter mark vibration, where the non-dimensional parameters are calculated with time varying signals and kurtosis under normal rolling mill operating conditions, is presented in this paper.

Scattered light sensor for chatter mark detection in nanometer scale
International Journal of Nanomanufacturing, 2012The detection and analysis of chatter marks in nanometer scale, using an angle resolved scattered light sensor, is discussed in this paper. After explaining the fundamental principles of scattered light sensors, a transfer function is obtained which yields the limit of wavelength that can be detected.

Relationship between chatter marks and rolling force fluctuation for twenty-high roll mill
Engineering Failure Analysis, 2015Abstract Chatter marks on the surface of a rolled steel strip may seriously affect the final product quality. It is still difficult to discover the generation mechanism of chatter marks and develop an effective method to identify chatter marks. In this paper a rolling force fluctuation model is proposed based on the variation of the rolling force ...

Abstract When chatter vibrations occur during cutting, a characteristic pattern called chatter mark appears on the machined surface. In our previous studies, it was estimated that this chatter mark is formed by the tool (or workpiece) vibration in the normal direction with respect to the machined surface.

INTER-NOISE and NOISE-CON Congress and Conference Proceedings, 2021
Intuition enables experienced machine operators to detect production errors and to identify their specific sources. A prominent example in machining are chatter marks caused by machining vibrations. The operator's assessment, if the process runs stable or not, is not exclusively based on technical parameters such as rotation frequency, tool diameter ...

Analysis of Chatter Marks in Accurate Grinding on Optical Curve Grinder
Key Engineering Materials, 2006Chatter marks that limit ground surface finish have been observed in accurate grinding by using optical curve grinder. To reveal the mechanism of chatter marks, the relationships between grinding parameters and chatter marks are experimentally studied. The profile of the ground surface is analyzed through microscope as well as FFT method.
