Abstract
A device for regulating a residual stress is comprised of: input means; a residual stress database; a process condition database; first searching means for searching a residual stress (σ0) from the residual stress database; a calculator for calculating a first bending moment (Mrs) in a ridge line originated from the residual stress, and a second bending moment (Mz) in the ridge line originated from bending to obtain a total bending moment (Mrs−Mz) and calculating a camber curvature (ρz) of the workpiece originated from the total bending moment (Mrs−Mz); comparing a difference (|ρz−ρz0|) between the camber curvature (ρz) and a target value (ρz0) with a tolerable value (ρ); second searching means for searching a process condition satisfying a tolerable condition (|ρz−ρz0|≦ρ) from the process condition database when (|ρz−ρz0|>ρ); and regulating means for regulating a residual stress.
