PROBLEM TO BE SOLVED: To provide a method and an apparatus for evaluating and checking a working process designing, a die-designing or a countermeasure of working defect, etc., after obtaining the inner part deforming information of complicated shape parts applying three-dimensional plastic deformation.;SOLUTION: A model die is used and a model material resembled with the deforming characteristic of a metallic material is used, and the model material embedding a gage mark is plastic-worked with the model die. The movement of the gage mark is picked up as one image by switching at one scene in the image at the timing in the irradiation with radiation from two directions forming a parallax and thereafter, the three-dimensional coordinate of the gage mark is calculated in arbitrary plastic working step from the working start to the working finish, from the two-dimensional gage mark image in two direction forming the parallax, and the gage mark data and the model die shape data are piled up and indicated.;COPYRIGHT: (C)2008,JPO&INPIT
