Self-excited Vibrations Avoidance Methodology in Non-linear Numerical Simulation Environment

A self-excited vibrations (chatter) are one of the most important limitation in machining performance and quality of finished parts as it is affecting its dimensional and geometrical accuracy. Selection of stable spindle speed can suppress self-excited vibrations occurrence, by disrupting regenerative effect. These and other technics can be tested during process planning via virtual machining - numerical simulation of non-linear chatter in the time domain. Developed algorithms software allows testing cutting parameters in virtual environment in order to receive chatter-free parameters.
