Stability analysis in face milling operations, Part 1: Theory of stabilitylobe prediction

This paper involves development of an algorithm to predict stability lobes in face milling operation. The modeling is based on frequency domain analys is and is an extension of Budak and Altintas to a three dimensional case. i t considers the effects of insert and cutter geometry, cutting conditions, process nonlinearity, entry and exit angles and the fully dimensional struc tural dynamics of both the machine tool and,workpiece, including axial dyna mics which are often neglected by many researchers. In addition, the predic tive capability of stability lobes by the presented models is compared with those results obtained by time domain simulations.
