Control method of chatter vibration based on inverse analysis of end milling chatter mark
Transactions of the JSME (in Japanese), 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.

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 ...

Suppression of chatter marks in surface grinding by using dynamic damper.
Journal of the Japan Society for Precision Engineering, 1987 In order to suppress the chatter marks due to the tuning-fork mode vibration of surfacegrinding machines, which is caused by intermittent contact of the wheel and the workpieceduring grinding operation, several types of dynamic dampers are developed and their effectiveness is investigated experimentally. It was found that in all cases the amplitudes of

Journal of the Japan Society of Precision Engineering, 1985 In order to clarify the mechanism of chatter mark generation in surface grinding by using horizontal spindle-reciprocating table type machines, experiments are conducted to measure the relative displacements between a grinding wheel head and a work table during various grinding operations, the dynamic characteristics of the surface grinding machines ...

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.
