Abstract

See full text

This fin tip position measurement method comprises: a jig installation step for installing a jig having a flat measurement surface expanded in a circumferential direction and an axial direction to a tip of at least one among a plurality of seal fins that protrude in a radial direction with respect to an axial line, extend in the circumferential direction, and are arranged in a direction in which the axial line extends; a first measurement step for measuring a distance from the axial line to the measurement surface by scanning the measurement surface with a laser beam; and a first calculation step for calculating a distance from the axial line to the tip of the seal fin by adding a radial dimension of the jig to the distance to the measurement surface.
