Abstract
The invention refers to a method for machining a blade and a blade for a turbomachine comprising a shroud which is positioned on a tip side of the blade. The shroud has an outer surface with at least one circumferential fin arranged thereon, whereby at least one section of the outer surface beside the at least one fin is processed in at least two manufacturing steps. At least one first section of the outer surface is processed to have a first shape and at least one second section of the outer surface is processed to have a second shape.

A method for machining a blade for a turbomachine comprising a shroud which is positioned on a tip side of the blade having an outer surface with at least one circumferential fin arranged thereon, whereby at least one section of the outer surface beside the at least one fin is processed, comprising the manufacturing steps of:
- machining the outer surface along a first machining path;
- and
- machining the outer surface along a second machining path which is different to the first machining path.
A blade for a turbomachine, comprising a shroud which is positioned on a tip side of the blade having an outer surface with at least one circumferential fin arranged thereon, whereby at least one area of the outer surface beside the least one fin is machined such that at least one first section of the outer surface has a first shape and such that at least one second section of the outer surface has a second shape that is different to the shape of the first section.
