摘要

PROBLEM TO BE SOLVED: To provide an apparatus, method and program for predicting shrinkage deformation of a molding, designed to enable efficient and highly accurate prediction of shrinkage deformation of the molding.SOLUTION: Fourth coordinate data which is a result of analyzing shrinkage deformation by a shrinkage deformation analysis process, and an analysis model as first coordinate data are verified by a flow of a calculation mode 2, thereby obtaining shrinkage deformation amount data in an inverse shrinkage deformation mode with respect to an original model corresponding to each back calculation revision ratio. Since the fourth coordinate data uses third coordinate data to which inverse shrinkage deformation is given by back calculation by multiplying a shrinkage factor mean value acquired from second coordinate data by a prepared each kind of revision ratio, the fourth coordinate data approximates to the analysis data which is the first coordinate data. The data in the fourth coordinate data corresponding to the back calculation revision ratios, and having the least difference in comparison with the analysis model, which is the first coordinate data, can be selected.
