Abstract
A method of repairing a rotating machine part. The method includes removing a damaged portion of a front end of an airfoil part of the rotating machine part, manufacturing a repair coupon having the same shape as the removed damaged portion by using a base material in an additive manufacturing method, and coupling the repair coupon manufactured through the manufacturing of the repair coupon to the front end of the airfoil part. Accordingly, after the damaged portion of the front end of the airfoil part of the rotating machine part is removed, the repair coupon having the same shape as the removed damaged portion is manufactured in the additive manufacturing method and then is coupled to the front end of the airfoil part from which the damaged portion is removed so that the front end of the rotating machine part can be easily repaired.
