Abstract

PURPOSE: To balance the compression residual stress with the cutting residual stress both generated on the surface of curvature cutting materials through eccentric shot peening by setting the rotation center of a shot spray head transferring along the curve of said curvature cutting material and the curvature center of said curvature cutting material apart from each other. CONSTITUTION: The curvature center O 1 of a U-pipe 1 and the rotation center O 2 of a shot spray head 3 are set at a fixed distance δ from each other in the opposite direction to a curved portion on a parallel line to the linear portion of said U-tube 1, said shot spray head 3 is rotated, and the compression residual stress and cutting residual stress both generated on the surface of said U-tube 1 are balanced with each other through eccentric shot peening to generate uniform residual stress on said surface.
