[0007] Furthermore, the necessary pulse-like voltage signals cannot be transferred by inductive or non-contact energy or signal transfer because the signal is often affected due to inductivity
If the induction delivers short pulse trains with a low frequency (approximately 1 to 5 kHz), the signal is disadvantageously highly distorted due to the high inductivity, making it impossible to apply patterns or surface structuring with the desired image quality
However, if slip rings are used for signal transmission while making contact, this is disadvantageous in industrial practice, in particular due to maintenance sensitivity due to wear and contamination
[0008] Thus, the prior art approach shows the disadvantages of large (and thus inconveniently dimensioned) tool holders and wire-constrained (or achieved by slip rings) energy transfer

The invention relates to a method and a device applying surface structuring to a surface of a workpiece on a machine tool, including performing a feed motion of a milling cutter which is rotationallydriven by a work spindle of the machine tool, received in a tool head of the machine tool and has at least one protruding cutting edge along the surface of the workpiece; applying the surface structuring in accordance with a predetermined pattern to the surface of the workpiece during the feed motion of the milling cutter on the basis of a control signal to an actuator which is integrated in the tool head and is configured to drive a vibration of the milling cutter on the basis of the control signal, wherein the control signal contains high-frequency carrier signal and a useful signal which modulates the carrier signal and which is generated on the basis of data indicating the predetermined pattern.
Description
technical field [0001] The invention relates to a method for applying surface structuring to the surface of a workpiece on a machine tool. The invention also relates to a device and a machine tool on which the above-mentioned method can be carried out. Furthermore, the invention relates to a computer program product which can be used to carry out the above mentioned method. Background technique [0002] DE 10 2012 002 140 B4 discloses a method of a general type for applying surface structuring to the surface of a workpiece, in particular a face milling method. Such surface structuring or marking of the surface can be used eg for decorative purposes or for encoding a component or workpiece by applying eg an image pattern and / or a text pattern to the surface of the workpiece. [0003] Here, milling cutters or face milling cutters can be used on machine tools, the cutters having, for example, axially protruding cutting edges which are not arranged in the tool shaft and which ...
