Abstract

Vibration modelling of machine tool structures F. Haase, S. Lockwood & D.G. Ford The Precision Engineering Centre, University of Huddersfield (UK) Abstract Productivity in modern machine tools is achieved by using high cutting velocities, spindle speeds and feed rates. A restriction for large material removal rates is the tendency of machines to chatter (structural vibration) for large depths of cut. This work is concerned with improving machine tool performance by understanding and ultimately controlling vibration in machine structures. If vibration due to chatter under load conditions can be controlled, then component surface finish can be improved and the life of components extended. The first step in this research is to measure and interpret vibration and model the structures, which are to be controlled. Appropriate sensors need to be selected and designed to measure self-excited vibrations. The vibrations of the investigated machines need to be understood
