Evaluation method of the surface distortion of the metal plate, the surface distortion of the metal plate evaluation value calculation device and program

摘要

PROBLEM TO BE SOLVED: To directly and quantitatively evaluate surface distortions of a metal sheet to be evaluated.;SOLUTION: Measurement values of the surface dimensions of the metal sheet 1 acquired by a measuring device 200 are input. An interpolation unit 102 interpolates the measurement values by the measuring device 200 into an orthogonal grid shape. A Gaussian curve calculation unit 103 computes a Gaussian curve through the use of values on orthogonal grid points, that is, measurement values when the measurement values by the measuring device 200 are on the orthogonal grid points and interpolation computation values when the measurement values by the measuring device 200 are not on the orthogonal grid points.;COPYRIGHT: (C)2011,JPO&INPIT
