摘要：The invention relates to a method for producing turbine rotor blades or thebase bodies (30) thereof, the frequency property of which can be adapted particularlyeasily to the required boundary conditions. To this end, recesses (50) are introduced intothe blade root (32) and/or by reducing a dimension below the corresponding target valueif the base body has (30) insufficient vibrational properties. In this way, a method isdisclosed in which the vibrational property of the turbine rotor blades can be set in aparticularly easy and variable manner. As a result, the reject rate in the production ofturbine rotor blades can be reduced.
