Abstract
In a method for machining a workpiece, a cutting tool is guided relative to the workpiece, with a vibration being superposed, the amplitude of which is at least 5 μm. A supply circuit for a piezo actuator of a vibrating tool generates a voltage at the voltage output, which has a direct component and an alternating component. A supply system for a piezo actuator of a vibrating tool has the above-mentioned supply circuit which is connected to a secondary coil that is coupled to a primary coil.
Claims20
A method for machining a workpiece by means of a cutting tool, where the tool performs a working movement relative to the workpiece, to which a vibration is superposed, characterized in that
- the vibration has an amplitude of at least 5 μm, preferably at least 10, 15 or 20 μm.
A supply circuit for an actuator of a vibrating tool, comprising
- an alternating current input,
- a first circuit part at a connection of the alternating current input with a capacitor,
- a second circuit part with a half-wave rectifier being in parallel to the series-connection of alternating current input and first circuit part, and
- a voltage pick-up for the voltage along the second circuit part as a voltage output.
A supply circuit for an actuator of a vibrating tool, comprising
- an alternating current input,
- a voltage generator which is connected to the alternating current input and has a voltage output and which is designed to have a direct component and an alternating component for generating a voltage at the voltage output.
