Stable milling of thin-walled parts with variable dynamics

Résumé

The milling of thin-walled parts can become a seriously complex problem. In this work, the problem of the variable dynamics of a test part has been solved through the calculation of 3D stability lobes which add a third dimension with the tool position along the part, to the traditional depth of cut-spindle speed pair. First, the dynamics of a test part in several machining steps have been calculated through FEM analysis and validated through experimental tests. Then, the stable conditions have been calculated with a one-dimensional and a three-dimensional stability model for the thin walls and the thin floor respectively. Finally, several milling tests have been performed in order to validate the predictions made by the model.
