Investigation of Control Methods of Chatter Vibration Based on Analysis of End-Milling Chatter Mark
Advanced Materials Research, 2015Chatter vibration generated by coupling a work-piece, machine tools, and cutting tool is a serious problem for engineers. A regular pattern forms the machined surface when chatter vibration occurs. There must be a direct relationship between the relative displacement and machined surface.

A Method of Chatter Marks Identification Based on Autocorrelation-Threshold
Key Engineering Materials, 2013Mill chattering is frequently observed in the strip rolling process which causes dark and bright fringes on the strip surface. Due to the complex vibration sources and the characteristic signals usually masked by the heavy noise signals, how to identify and control the mill chattering are always difficult problems.

Alleviation of regenerative chatter using MRF dampers during milling
RENEWABLE ENERGY SOURCES AND TECHNOLOGIES, 2019Regenerative chatter, a resonant phenomenon where the machine or work piece vibrates during machining process generates waviness which gives rise to poor surface finish in work piece.

Investigation of chatter marks on ground surfaces by means of optical methods
Optics and Lasers in Engineering, 2011Abstract In order to characterise chatter marks, in this work, various ground samples are investigated by means of two different optical surface analysis techniques: by using a confocal white light microscope and an angle-resolved light scattering sensor, respectively.

Chatter Marks and Vibration Analysis in a S6-High Cold Rolling Mill
2013S6-high rolling mill is an advanced mode to work the steel: it allows the use of very small work rolls laterally guided by individually adjustable side support rolls, which are supported by two rows of roller bearings mounted in cassettes. In this paper the vibrations generated in a S6-high cold rolling mill are analyzed with the aim to investigate the

Model-Based Identification of Chatter Marks during Cylindrical Grinding [PDF]
, 2013 The following paper presents an online model-based monitoring algorithm that identifies and quantifies the level of waviness caused by grinding chatter exploiting accelerations measured on the machine. A Weighted Least Squares method has been applied in the frequency domain that leads to a clear interpretation of the forcing effect caused by the ...

CIRP Annals, 1981
Summary This paper is concerned with how to display effectively 2D surface roughness, which was measured by using light sectioning method and by taking self-excited chatter marks as objective. The marks due to chatter which was mainly caused for work and tool respectively are taken.

Spatial Frequency Analysis of Chatter Marks
2018Chatter vibration induces a characteristic pattern on the milled surface, known as chatter marks, causing a poor surface quality. This paper investigates the chatter marks generation mechanisms focusing on their distribution, i.e., the surface spectral proprieties.

Chatter marks generation mechanisms in peripheral milling
2017Machined surface quality, key aspect of milling process performance, is affected by chatter vibration that produces distinctive marks on the surface. While several works have been proposed on the prediction of the machined surface in stable condition, surface under chatter vibration has not been extensively studied.
