A method for manufacturing a workpiece, in particular a turbine blade, using a milling tool configured as a conically convex milling cutter, wherein the conically convex milling cutter comprises - a shank and - a conically convex milling cutter portion connected at the end to the shank directly or through a transition, wherein the conically convex milling cutter has a first and a second cutting area (24, 26), wherein the first cutting area is provided on the shank or/and at the transition, and wherein the second cutting area is provided on the conically convex milling cutter portion, wherein the method comprises the following steps: A) roughing a blank portion using the conically convex milling cutter, wherein the latter is inclined relative to a current feed direction at a reference point of the conically convex milling cutter within a first machining angle range (α1, β1) such that machining is performed with the first cutting area of the conically convex milling cutter, wherein the second cutting area remains passive during machining, and B) finishing at least a part of the rough blank portion using the conically convex milling cutter, wherein the latter is inclined relative to the current feed direction at the reference point of the conically convex milling cutter within a second machining angle range (α2, β2) in such a way that machining is performed with the second cutting area of the conically convex milling cutter, wherein the second cutting area engages with the blank. wherein the conically convex milling cutter comprises - a shank and - a conically convex milling cutter portion connected at the end to the shank directly or through a transition, - a shank and - a conically convex milling cutter portion connected at the end to the shank directly or through a transition, wherein the conically convex milling cutter has a first and a second cutting area (24, 26), wherein the first cutting area is provided on the shank or/and at the transition, and wherein the second cutting area is provided on the conically convex milling cutter portion, wherein the method comprises the following steps: A) roughing a blank portion using the conically convex milling cutter, wherein the latter is inclined relative to a current feed direction at a reference point of the conically convex milling cutter within a first machining angle range (α1, β1) such that machining is performed with the first cutting area of the conically convex milling cutter, wherein the second cutting area remains passive during machining, and B) finishing at least a part of the rough blank portion using the conically convex milling cutter, wherein the latter is inclined relative to the current feed direction at the reference point of the conically convex milling cutter within a second machining angle range (α2, β2) in such a way that machining is performed with the second cutting area of the conically convex milling cutter, wherein the second cutting area engages with the blank.
