Abstract:
1. The use of a distributor or diffuser in the form of a thin-walled, completely or partially air-permeable, heat-reactive layer for drilling or milling machining of a workpiece with a tool, comprising: producing a vacuum surface tension for fixing a position of the workpiece using a vacuum over the layer acting as a distributor or a diffuser on a surface of the workpiece to be machined; machining the workpiece, wherein a cutting speed and/or rate of feed is adjusted, such that a defined local heating takes place in a contact area between the tool and workpiece, whereby a temperature peak at the contact area is greater or the same as a melting temperature of the surface of the distributor or diffuser; and releasing the vacuum surface tension and detaching the workpiece after completed machining of the workpiece.
