摘要： A method of modifying an existing casting mold for a turbine moving blade having a shroud band segment with an initial coupling geometry for coupling with a further shroud band segment, the coupling geometry having an initial coupling angle of the shroud band segment relative to a circumferential direction of the turbine, includes calculating a modified coupling geometry for the shroud band segment, the modified coupling geometry including a modified coupling angle of the shroud band segment relative to the circumferential direction. The method further includes creating at least one of a removal zone and an application zone, wherein the creating of the removal zone includes removing a first amount of casting mold material from the removal zone and wherein the creating of the application zone includes applying a second amount of an additional casting mold material to the application zone, wherein the removing and the applying steps result in the casting mold having the modified coupling angle.

摘要： A method of modifying a coupling geometry in a shroud band segment of a turbine moving blade includes the following steps: calculation of a modified coupling geometry; removal of shroud band material situated outside the modified coupling geometry; and/or application of additional material not present inside the modified coupling geometry; reworking the removal and/or application zones. The method avoids disadvantages of the prior art and provides improved wear behavior in the coupling region so as to prolong the life of the turbine blades in an effective and inexpensive manner.
