Kurzbeschreibung (Abstract)
Numerous investigations work on torsional chatter vibrations in drilling. Particularly in terms of productivity, torsional chatter is detrimental because of a reduction of tool life and an undesirably high level of noise emissions due to the increased process dynamics. To achieve a deeper understanding of the process dynamics, a new nu-merical simulation model was developed to predict torsional chatter for extra-long twist drills. It is used to de-termine the influence of numerous factors such as cutting parameters, drill torsional stiffness, rotary moment of inertia and torsional-axial coupling. In this paper, the gen-eral structure of the model and the tool model is presented.
