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 ad 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.
Claims23
A method for performing a blending operation on a damaged engine component, the method comprising:
- operating the blending operation on a damaged region of the damaged engine component based on an initial blending profile;
- detecting repaired conditions of the damaged region while the blending operation is performed, wherein the detecting captures strain data of the damaged region using a sensing device, and wherein the detecting is performed either periodically during the blending process or substantially real-time during the blending process;
- processing the strain data to calculate a detected strain level;
- adjusting the blending profile if the detected strain data fails to meet predetermined criteria, wherein the predetermined criteria includes an acceptable strain level;
- and
- operating the blending process on the damaged region based on an adjusted blending profile, wherein the blending operation is completed when the detected strain level of the damaged region meets the acceptable strain level.

A method for repairing a turbine component, the method comprising:
- inspecting the turbine component which has at least one defect;
- generating an initial blending profile on the at least one defect;
- performing a blending operation on the at least defect based on the initial blending profile to repair the turbine component;
- detecting strain data of the at least one defect during the blending operation;
- adjusting the initial blending profile based on detected repaired data to generate an adjusted blending profile;

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.
