Abstract
Depending on the machining process chatter might occur at an eigenfrequency of the machine's structure. Electrodynamic proof-mass actuators can be attached to the structure in order to mitigate chatter. This paper gives an overview of different existing control strategies for active damping and compares them with one another. First, the control strategies were implemented and tested in a coupled simulation model. Then, the simulation results were validated by modal tests. For a sample process the analytically predicted depths of cut were finally verified in cutting tests.
