Abstract

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.
