Abstract
A method of repair includes removing a deformed portion of a component to define a native component portion and adding a replacement portion to the native component portion. The replacement portion is adaptively machined based on one or more parameters of the native component portion and based on one or more original design parameters of the component.
Claims5
A method of repair, comprising:
- removing a deformed portion of a component to define a native component portion;
- measuring actual points on the native component portion in a first measuring step;
- adding a replacement portion to the native component portion;
- measuring actual points on the native component portion in a second measuring step and subsequent to inclusion of the replacement portion to determine deviations in measurement of points obtained in the first measuring step;
- identifying a rigid patch and a warp patch on the native component portion based on deviations between actual measurements on the native component portion and a computer model;
- adding points in the warp patch to obtain smooth transitions;
- registering the computer model of the component to a fraction of the actual points on the native component portion;
- altering the computer model based on the actual points and the original design intent to generate a transformation model;
- modifying a nominal tool path according to the transformation model to generate a deformed tool path;
- and
- adaptively machining the replacement portion utilizing the deformed tool path and according to original design parameters of the component.
