ADAPTIVE MACHINING TURBOMACHINE BLADE SHROUD HARD FACE

摘要

A system for adaptively machining a shroud (134) of a blade (140) used in a turbomachine is provided. The system may include a computer system including a module(s) configured to: extract geometric location data from a 3D model of the shroud (134) after use in the turbomachine, the 3D model created by digitizing using a digitizing device (130). The geometric location data includes geometric location data of a hard face plane (D1,D2) of the shroud (134) exposed to wear during turbomachine operation and of a non-worn surface (136, 138) adjacent to the hard face plane (D1,D2) substantially unexposed to wear during turbomachine operation. Comparing the geometric location data of the non-worn surface (136, 138) from the three-dimensional model (132) to a manufacturing model (150) of the blade (140) determines a change in position of the non-worn surface (136, 138) from use of the blade (140) in the turbomachine. The change in position is used to modify a machining instruction used by a machining device (111) to repair the hard face plane (D1,D2).
