Abstract
The presented work is part of a project aimed at improving machine tool
performance due to forced and self-excited vibration. Adaptive algorithms used
in digital signal processing (DSP) are implemented in order to model machine
tool structures and control the vibration. Self-excited machine tool vibration
occurs when the cutting load exceeds the dynamic stiffness of the machine. The
phenomenon is called chatter and has a direct impact on the surface finish, tool
life and productivity. To avoid this, an experienced machine tool operator would
try to change the cutting parameters or the clamping of the tool and work-piece.
The aim for this research is to model machine tool structures adaptively in the
digital domain, in order to control self-exited, but also forced vibration of
mach
