ADJUSTMENT AMOUNT ESTIMATION APPARATUS, ADJUSTMENT AMOUNT ESTIMATION METHOD AND ADJUSTMENT AMOUNT ESTIMATION PROGRAM

WIPO Patent Application WO/2020/250779

A1

This adjustment amount estimation apparatus (100) comprises: a data acquisition unit (41) which measures, via a communication unit 70, coordinates of a point on a surface included in a constituent component of a machine; and a geometric error computation unit (43) which, on the basis of the measured coordinates, computes a geometric error in the surface with respect to a reference value for geometric characteristics such as the shape, the attitude, or the position of said surface. Prior to machine assembly, the geometric error computation unit (43) executes, on the basis of the pre-assembly geometric error in the constituent component, a predictive calculation of post-machine assembly displacement of the surface from a reference position, and uses the displacement obtained by the predictive calculation to compute an adjustment amount for an adjustment member which changes the geometric characteristics of the surface.
