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

The chatter mark vibration generated in the rolling process of the twenty-high roll mill not only significantly affects the mill performance, but also reduces surface quality of the strip steel. To identify the excitation source, the online monitor for the real time torsional strain of the main drive shaft is performed for a Sendzimir twenty-high roll ...

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.
