PROBLEM TO BE SOLVED: To properly exhibit a correction effect, when correcting bending of a work-piece by pressing with a pressing member.SOLUTION: A bending correction method of a work-piece W comprises: a measurement step of measuring a deflection amount from a central line X1 of the work-piece W; and a correction step of correcting bending of the work-piece W due to deflection from the central line X1 by pressing a portion where the deflection amount becomes maximum in a direction for reducing the deflection amount from the central line X1, and in the bending correction method of the work-piece W, the measurement step and the correction step are repeated until the deflection amount from the central line X1 becomes less than a threshold value. In the correction step to be performed on and after a second time, a portion where the number of times of pressing up to the last time correction step is the least, and where the deflection amount from the central line X1 is the maximum, is pressed. |
