<p>PROBLEM TO BE SOLVED: To perform molding of a good measurement accuracy and of a small surface roughness. SOLUTION: For molding a plate material 6 with a first pressing element 3, which is capable of pressing one face of the plate material 6 in a plate thickness direction, and a second pressing element 4 which is capable of pressing the other face of the material 6 in the plate thickness direction, a shape of the first pressing element 3 is made in a manner to follow the whole inner surface of the plate material after its mold processing is performed. In this case, the second pressing element 4 presses the plate material 6 to the first pressing element 3 relatively so as to perform the molding. Also, a force which relatively presses the plate material 6 to the first pressing element 3 by the second pressing element 4, is controlled based on a compression force to be added to the plate material 6.</p> |
