Chatter in manufacturing system: Prediction and detection [PDF]
TehnikaChatter is a phenomenon that periodically occurs in machining systems. Its occurrence in machining processes excites the tool and other elements of the machining system, creating "chatter marks" on the workpiece surface, which affects the quality of the ...

Chatter Control by Spindle Speed Variation in High-Speed Milling [PDF]
, 2009 High-speed milling operations are often limited by regenerative vibrations. The aim of this paper is to analyze the effect of spindle speed variation on machine tool chatter in high-speed milling. The stability analysis of triangular and sinusoidal shape

Proposal of novel chatter stability indices of spindle speed variation based on its chatter growth characteristics [PDF]
, 2020 Chatter is one of the most critical problems that causes poor surface quality and restriction of machining efficiency. Spindle speed variation (SSV) is a well-known technique for suppression of regenerative chatter. However, in the authors’ understanding,

Active chatter suppression through virtual inerter-based passive absorber control [PDF]
, 2022 The role of inerter-based devices has generated considerable interest in terms of suppressing the vibrations in machines and structures. The inerter is a mechanical device that generates force proportional to the relative acceleration between its ...

Generalized design method of highly-varied-helix end mills for suppression of regenerative chatter in peripheral milling [PDF]
, 2017 Peripheral finishing of hardened steel by milling has recently been introduced to the machining field, but often causes severe chatter vibration due to high specific cutting force and low stiffness of slender end mills.
