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 ...

The use of the chatter mode in self-adaptive systems [PDF]
, 1970 Chatter mode is used advantageously if the ideal model dynamics is described by a switching function, the chatter mode is reached quickly and then sustained, the chatter frequency is reduced, and any zero in the plant transfer function is ...
