Analysis of Chatter Vibration and Tool Deflection in Milling with a Novel Active Machine Tool Guide

Abstract:

Chatter vibrations and tool deflection are common challenges in metal cutting processes. In roughing operations, it is often the occurrence of chatter vibrations which limits the productivity. While finishing, when tolerances are small, the tool deflection can lead to violating tolerances and thus producing scrap parts. Beside the tool and tool holder, it is also the guidance system, especially in the z-axis, which influences the aforementioned phenomena. In this paper the influence of an electromagnetic guided z-axis is presented. It is focused on the influence of the high damping and the high static stiffness of the guide. Further benefits of this technology are outlined.
