ARITHMETIC DEVICE, ARITHMETIC METHOD, AND PROGRAM

To estimate intrinsic strain with high accuracy.SOLUTION: An arithmetic device includes: a deformation acquisition part that acquires a measured deformation amount, which is the amount of shape deviation from a target shape, of a molded object manufactured based on the target shape; an analysis part that executes analysis based on the target shape of the molded object and a reference specific strain value which is a reference value of the specific strain of the molded object, and obtains the analysis deformation amount which is the amount of deviation of the shape of the molded object from the target shape in the analysis; and a strain calculation part that calculates an estimated intrinsic strain value, which is an estimated value of the intrinsic strain of the molded object having the target shape, based on the measured amount of deformation and the analyzed amount of deformation.SELECTED DRAWING: Figure 7 【課題】固有ひずみを高精度に推定する。【解決手段】演算装置は、目標形状に基づいて製造された造形物の、目標形状からの形状のずれ量である実測変形量を取得する変形量取得部と、造形物の目標形状と、造形物の固有ひずみの参照値である参照固有ひずみ値とに基づき、解析を実行して、解析における造形物の、目標形状からの形状のずれ量である解析変形量を取得する解析部と、実測変形量と前記解析変形量とに基づき、目標形状の造形物の固有ひずみの推定値である推定固有ひずみ値を算出するひずみ算出部と、を含む。【選択図】図７
