Beschreibung
Regenerative chatter, which is a well-known unstable phenomenon in macro-scale machining, can also occur in micro milling and leads to insufficient quality of products, premature tool wear, and tool damage. To predict the chatter stability, the dynamics of the machine tool system should be identified either by experiments or by (semi-)analytical models. Due to the process-machine-interactions, it is usually insufficient to treat the micro end mills as an oscillator or as a cantilever beam for chatter prediction. In this dissertation the systematic modeling of a micro milling machine tool system is presented considering the micro end mills, the spindle–tool holder–tool assembly, and other fundamental components.
