  • Publication number: 20220326114
    Abstract: Provided is a reusability determination method for a gear that makes it possible to determine reusability of a gear during or after use to increase the reuse ratio. The reusability determination method for a gear of the present invention includes a step of measuring a content of retained ? phases in the gear, a step of calculating a change rate of the content of the retained ? phases, a step of measuring residual stress applied to the gear, a residual stress ratio calculation step of calculating a residual stress ratio to residual stress in an initial state of the gear, and a reusability determination step of determining whether or not the gear is reusable on the basis of results of the calculation in the retained ? phase change rate calculation step and the residual stress ratio calculation step.

  • Patent number: 9238288
    Abstract: In a method for processing a plate object, etching is performed for a flat plate object by a predetermined etching method and the shape of the plate object after the etching is grasped in advance. In a grinding step, the plate object is ground into a grinding-finished shape that is a non-flat shape obtained by inverting the shape of the plate object after the etching to the reverse shape. When subsequent etching by the predetermined etching method is performed for a grinding-target surface, the plate object is formed into a flat shape with a uniform thickness.
