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

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. 调整量推定装置(100)具有：数据取得部(41)，其经由通信部(70)对机械的结构部件所包含的面上的点的坐标进行测定；以及几何学误差运算部(43)，其基于测定出的坐标，运算面的形状、姿态
