PROBLEM TO BE SOLVED: To sequentially form formed surfaces that form other three-dimensional shapes each having a wall part and a top part or a bottom part intersecting a reference surface, within a forming section determined in the reference surface that forms three-dimensional shape in a plate with a sequential forming tool.SOLUTION: A sequential forming method for a plate 1 includes: performing a machining pass of moving a sequential forming tool 20 relative to a wall part 3A of a formed surface 3 in the plate 1 along a forming section 2A of a reference surface 2 forming three-dimensional shape in the plate 1; and repeating the machining pass through the predetermined pitch in a direction to intersect the reference surface 2 forming the three-dimensional shape in the plate 1, thereby sequentially forming wall parts 3A. |
