Abstract


Due to the dynamic behavior of the milling machine, the milling operation can proceed from the stable milling domain in the unstable domain although the depth of milling, the cutting speed and feed rate are rigorously calculated. The stable milling domains can be identified through stability charts which are calculated with specific algorithms that use as input data the modal parameters of the milling machine. We calculated and drew the stability diagrams modeling the cutter vibrations as a one degree of freedom oscillator. For this we implemented the semi-discretization algorithm in software written in Pascal language.  

Keywords: milling machine, stability diagram, semi-discretization algorithm
