Abstract:
1. Milling method for the production of a structural component from a material, while producing a depression with at least one sidewall, whereby a milling tool having a tool radius is rotationally driven about an axis of the milling tool to carry out a central rotation thereof, whereby a reference point of the milling tool lying on an axis of the milling tool is moved on several curved paths, whereby the paths respectively comprise different curvatures, and whereby the milling tool is moved with a radial miller feed relative to the material on the paths, characterized in that, after reaching a maximum permissible circumferential contact of the milling tool with the material, the curvature at each path point of each path is determined dependent on the tool radius of the milling tool, the depression to be milled, and a milling contour of an immediately previously followed one of the paths, in such a manner so that at each path point the circumferential contact of the milling tool with the material is optimized to the maximum permissible circumferential contact.
