Abstract
An adaptive blending system and method are disclosed. A blending operation is performed on defects of a turbine engine component based on an initial blending profile. The adaptive blending system and method dynamically observes and detects strain data of the defects during the blending operation. The detected strain data of the defects are sent to a processor for analysis in a substantially real-time basis to obtain strain levels of the defects. The processor generates a strain level of a defect based on the detected strain data, and generates an adjusted blending profile for use in the blending operation.
Claims20
A system for removing residual stress of a damaged turbine component, the system comprising:
- a blending tool for blending a damaged region of the damaged turbine component, the blending tool including a blending head for blending and smoothing a surface of the damaged region, wherein the blending tool performs a blending operation on the damaged region based on a blending profile;
- a sensing device for observing and sensing repaired conditions of the damaged region during the blending operation, the sensing device detecting strain data of the damaged region and sending the strain data to an analyzing device;
- and
- the analyzing device for analyzing and processing the detected strain data to compare with predetermined criteria stored in a database, wherein
- the analyzing device calculates a strain level based on the detected repaired data and compare the calculated strain level with a threshold strain level among the predetermined criteria,
- if the calculated strain level fails to meet the threshold strain level, the analyzing device generates adjustment data based on the predetermined criteria to adjust the blending profile.
