HOLE COVERING CURVED-SURFACE GENERATION DEVICE AND PROGRAM FOR HOLE COVERING CURVED-SURFACE

摘要

PROBLEM TO BE SOLVED: To generate a hole covering curved surface having a smooth shape without undulation (change of a curvature) and discontinuity in a surface.;SOLUTION: A hole covering curved-surface generation device includes: a first deformed mapping commitment part 13 for obtaining a first deformed mapping Ψ (approximate deformed mapping Ψapprox.) which satisfies a first restrictive condition relating to the position approximation and the curvature change minimization; a second deformed mapping commitment part 23 for obtaining a second deformed mapping Ψ (interpolation deformed mapping Ψinterp.) which satisfies a second restrictive condition relating to the position continuity and the direct continuity; and a shape deformation part 24 for generating a hole covering curved surface for covering a hole on the surface of an object shape by performing a shape deformation processing on an initial curved surface temporarily set against a hole of the object shape, by using the synthesized mappings Ψapprox and Ψinterp. A deformation toward a smooth shape having no undulation is realized on the basis of the first deformed mapping, and the deformation toward the smooth shape having no "discontinuity" is realized on the basis of the second deformed mapping.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
