Abstract

Vibratory problems encountered when milling a thin walled structure affect the surface quality of the finished workpiece and to a lesser extent, the life of the tool and the spindle. This is why, it is necessary to be able to limit these problems by an appropriate choice of the cutting conditions. The stability lobes theory allows to choose the suitable cutting conditions according to the dynamic behaviour of the workpiece and the tool. We introduce here the variations of dynamic behaviour due to the tool position, in order to obtain optimum cutting conditions all along the machining. This general implementation of the classical stability lobes graph leads us to represent the lobes in three dimensions. These theoretical results are compared with experimental milling of thin walled structure, in down-milling.
