Control method of chatter vibration based on inverse analysis of end milling chatter mark

Nihon Kikai Gakkai ronbunshu, 2017
It is well known that a regular chatter mark appears on the machined surface when chatter vibration occurs. There must be an essential information relationship between the chatter mark and the vibration stability.

State estimation based on image processing of chatter mark on end-milled surface by two-dimensional discrete Fourier transform

Nihon Kikai Gakkai ronbunshu, 2019
In this report, we propose a method to analyze the frequency and phase difference of self-excited vibration during cutting by using image analysis for the photographed image of the machined surface by end milling.

Study on the Relationship between Chatter Mark Vibration and Rolling Skid for a Twenty-High Roll Mill Based on the Measured Torsional Strain of the Main Drive Shaft

Advanced Materials Research, 2012
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 ...

Investigation of Control Methods of Chatter Vibration Based on Analysis of End-Milling Chatter Mark

Advanced Materials Research, 2016
Chatter 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

On the generation of chatter marks in peripheral milling: A spectral interpretation

International Journal of Machine Tools and Manufacture, 2018
Abstract Chatter vibration induces a characteristic pattern on the milled surface, known as chatter marks, causing a poor surface quality. While several works deal with the prediction of the machined surface in stable condition, surface under chatter vibration has not been extensively studied: it is not clear how vibrations at high chatter frequency ...

EFFECTS OF CHARACTERISTICS OF HYDRAULIC SYSTEM OF SURFACE GRINDING MACHINE UPON CHATTER MARK FORMATION IN GRINDING AND THEIR CONTROL

Proceedings of the JFPS International Symposium on Fluid Power, 1989
This paper, firstly, describes the generation of small pitch parallel line chatter marks on the workpiece surface. Experimental results show that the pressure pulsation produced by the vane pump makes the wheelhead and the work table of the machine vibrate which results in small pitch chatter mark formation.
