Percentage stopping/deciding method, rotor production method, and percentage stopping/deciding device

摘要

In the percentage stopping/deciding method of the plate shaped material, the rectilinear concave section 2 places or more is formed in the plate shaped material, the plate shaped material 3 or more thing and the plate shaped material which percentage stopping/deciding are done with the direction where the rectilinear concave section crosses, positioning keeps with positioning expedient, the 1st positioning process which positions the 1st rectilinear concave section and, keeps one side of the 1st rectilinear concave section with the fixing clamp, another side makes 1st clamp process and the positioning expedient evacuate which holding are done with the rotating clamp, while keeping specified clamp power, turns makes the rotating clamp alienateIt cancels the clamp of 1 percentage stopping/deciding process and the fixing clamp and the rotating clamp, the 2nd positioning process which positions the 2nd rectilinear concave section with positioning expedient, and, it keeps one side of the 2nd rectilinear concave section with the fixing clamp, another side it makes 2nd clamp process and the positioning expedient evacuate which holding are done with the rotating clamp, the 2nd percentage stopping/deciding process which while keeping specified clamp power, it turns alienates the rotating clamp and, it possesses.
