METHOD FOR SETTING EXCESS THICKNESS, DEVICE FOR SETTING EXCESS THICKNESS, METHOD FOR PRODUCING SHAPED OBJECT, AND PROGRAM

WIPO Patent Application WO/2020/129560

A1

The present invention comprises: a thermal shrinkage prediction step for predicting the amount of post-shaping thermal shrinkage of a laminate; a thermal shrinkage correction step for expanding the target profile of a shaped object in accordance with the amount of thermal shrinkage to obtain a thermal deformation correction profile; a released strain prediction step for predicting the amount of elastic deformation according to post-machining released strain of the laminate; an elastic deformation correction step for deforming the thermal deformation correction profile in accordance with the amount of elastic deformation in a direction opposite the deformation direction according to the released strain to obtain an elastic deformation correction profile; and an excess thickness setting step for adjusting the contour shape of the laminate so that the excess thickness from the elastic deformation correction profile to the contour of the laminate is within a predetermined reference range.
