Abstract:
1. A milling method for the production of a structural component having a desired final contour to be produced by milling from at least one material that is difficult to machine by chip-cutting, while producing depressions with at least one sidewall, whereby a milling tool is moved along at least one defined tool path for the milling, characterized in that, in addition to the or each tool path, at least one collision contour respectively corresponding to a surface or an edge of the at least one sidewall of the desired final contour of the structural component to be produced is defined and the position or orientation of the milling tool along the or each tool path relative to the or each collision contour is monitored in an automated comparison of the or each tool path with the or each collision contour to determine whether an expected collision exists between the milling tool and the at least one collision contour corresponding to the surface or the edge of the desired final contour of the structural component to be produced, and if the expected collision is determined to exist then the position or orientation of the milling tool is changed and/or an error message is generated to avoid the structural component being damaged by the milling tool.
