Abstract: In a method for severing a solid body, a defined contour is stored in a control unit configured to detect contour breaches and to avoid contour breaches. A high-energy beam is moved along a contour on a surface of the solid body, with the surface of the solid body facing the high-energy beam, to produce with the high-energy beam a cutting gap. The contour on the surface is compared with the defined contour stored in the control unit, and avoidance of the contour breach is automatically deactivated when the contour on the surface of the solid body matches the defined contour and a contour breach is detected. Otherwise, the contour is omitted. Advantageously, the high-energy beam travels along the contour with an averaged line movement.

Abstract: In a method for 3D radius correction in CNC milling, a mill path of an original milling tool producing a surface contour on a workpiece is calculated for an original milling tool based on dimensions of the mill cutter tip, with the positions of the mill cutter tip specified by an NC program. A surface normal of an end face milling surface and a surface normal of a circumferential milling surface are then specified, for each position of the mill cutter tip taking into account dimensional differences between an actually available milling tool and the original milling tool. By specifying along the mill path a spatial orientation of the milling tool axis, a correction vector is specified from the milling tool orientation, dimensional differences and the surface normals, and the workpiece is machined by traversing the mill path with the actual milling tool under consideration of the correction vector.
