Definition
The term chatter prediction describes a range of simulation methods, which are used to predict chatter vibrations (instabilities). These methods are based on the dynamic compliance of the machine tool structure as well as on the dynamics of the machining process. The whole machine behavior can be expressed in terms of mathematical descriptions (coupled structure-process models), from which stability lobe diagrams can be derived.
Theory and Application
Chatter
In the context of chatter prediction, chatter describes a self-excited vibration occurring during a metal-cutting machining process. Its vibration frequency is close to the eigenfrequency of the most compliant eigenmode of the excited machine structure. According to Totis (2009), chatter can be classified as primary or secondary. Primary chatter (e.g., friction on contact surfaces, stress distribution on the normal rake face, thermoplastic behavior of the chip material, and mode...
