摘要

PROBLEM TO BE SOLVED: To provide a method for predicting a deformed shape of a molding, which predicts an accurate deformed shape by reducing a difference between an actual shrinkage and a predicted value.;SOLUTION: The method for predicting a deformed shape of a molding has the steps of: in preparation for predicting a deformed shape, calculating shrinkage table data by associating a shape feature calculated on the basis of a particular format of shape data similar to a molding shape to be predicted with a measured shrinkage ; calculating a shape feature on the basis of shape data on the molding shape to be predicted, reading the corresponding measured shrinkage from the prepared shrinkage table data, and calculating shrinkage strain data from them; and predicting a deformed shape of a molding from the calculated shrinkage strain data.;COPYRIGHT: (C)2010,JPO&INPIT
