Abstract: A method is provided for material-removing machining when moving a tool of a machine tool along a tool path, including providing a workpiece comprising a first workpiece portion and a second workpiece portion adjacent to the first workpiece portion, wherein the tool path comprises a first path section comprising path segments adapted to a geometry of the first workpiece portion, and a second path section comprising path segments adapted to a geometry of the second workpiece portion. The method comprises determining the first path section to cover the first workpiece portion except for a first edge section, determining the second path section to cover the second workpiece portion except for a second edge section, and determining a transition section of the tool path to cover the first edge section and the second edge section, such that the first and second path sections and the transition section cover the entire first and second workpiece portions.

Abstract: The present invention relates to a method for generating a tool path (20; 82) for an application tool (12) for additive manufacturing, in particular for additive manufacturing using buildup welding, of a substantially rotationally symmetric workpiece (28; 328), comprising the following steps: a) providing cross-sectional contour data describing at least a portion of a cross-sectional contour (42; 342; 442; 542) of the workpiece (28; 328); b) providing axis data describing a rotation axis (R) of the rotationally symmetric workpiece (28; 328); c) generating a continuous cross-sectional path (54; 354; 355; 454; 554), taking into account the cross-sectional contour data, the cross-sectional path (54; 354; 355; 454; 554) being inscribed in the portion of the cross-sectional contour (42; 342; 442; 542); d) generating the tool path (20; 82) with a helical or/and spiral course revolving around the rotation axis (R), wherein the tool path (20; 82) intersects the cross-sectional path (54; 354; 355; 454; 554), prefer
