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
