    • A device and a method are disclosed for attenuating a chatter oscillation in a processing machine, for example a cutting machine, such as a lathe. The machine includes at least one feed system with a primary section and a secondary section driven by a linear motor which can be powered via a converter. The device has a magnetic field control to control an in-phase component (d-component) of the magnetic field which produces the attractive force between of the primary section and the secondary section. An actual signal that is proportional to the chatter oscillation is generated and compared with a predetermined setpoint for a chatter oscillation. The comparison produces a control variable which is applied as a current setpoint to a field control that controls the current of the linear motor. This sufficiently attenuates chatter oscillations so that a reduction of the cutting depth is no longer required.
