Title:
METHOD FOR MACHINING FEATURE PART IN LASER SHOCK PEENED REGION
Document Type and Number:
Japanese Patent JP2008260064
Kind Code:
A
Abstract:
To enlarge the wear resistance of a hole and the other machined feature parts and also to further extend especially when those feature parts are equivalent to the limiting portion of the life of components.
This method includes: a step where laser shock peening is performed on the planned surface 54 of the laser shock peening of an article 8; a step where at least one prestressed region 56 having deep compressive residual stress imparted by the laser shock peening and extending from the laser shock peened surface 55 to the interior of the article 8 formed by the laser chock peening is formed; and a step where the feature parts 9 are machined in the article in the prestressed region 56 after performing the laser shock peening.
