摘要

The method for the manufacture of a contoured and finely structured surface of a tool for the producing of a plastic film entails producing the contour and fine structure by means of a numerically controlled machine tool in a machine cutting. The data used for control of the machine comprises contour data, which three-dimensionally describes the contour of the plastic film, and fine structure data which three-dimensionally describes the image of the surface of an original pattern (4). The contour data and fine structure data is added together for control of the machine tool. An independent claim is included for a device for carrying out the method according to the invention comprising a numerically controlled milling machine.
