Method for milling a blank in the production of a turbine blade |
| 摘要 |
A method for milling a blank in the production of a turbine blade which in the final state has at least one blade root for fastening to a carrier and also an adjoining blade body extending in the longitudinal direction includes clamping the blank on its root side in a mount and machining the blank with a milling cutter. Machining the blank includes moving the milling cutter in an advancing direction for roughing machining while superimposing a circular movement as per a trochoidal milling method. |

1. A method for milling a blank in the production of a turbine blade which in the final state has at least one blade root for fastening to a carrier and also an adjoining blade body extending in the longitudinal direction, the method comprising:
clamping the blank on its root side in a mount; and machining the blank with a milling cutter, wherein machining the blank comprises moving the milling cutter in an advancing direction for roughing machining while superimposing a circular movement as per a trochoidal milling method, wherein a diameter of the milling cutter lies in the range of from about 40% to about 70% of a width to be machined of the blank. |
