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.

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 ...

Identification of Machining Chatter Marks on Surfaces of Automotive Valve Seats
Journal of Manufacturing Science and Engineering, 2011In this paper, we propose a method for inspecting machining chatter marks on automotive valve seats using image processing technique. Chatter or self-excited tool-workpiece relative vibration is unacceptable in the machining processes of valve seats, because it causes poor surface finish and can create internal leaks in the engine.

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.

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.

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 ...

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 ...
