POSITIONING SYSTEM, POSITIONING METHOD, STRUCTURE MANUFACTURING METHOD, AND DIE WITH ALIGNMENT MARK

摘要

PROBLEM TO BE SOLVED: To provide a positioning system capable of easily acquiring positions of a rotating tool and a work relative to each other, and capable of easily positioning the rotating tool and the work.SOLUTION: A positioning system 10 includes: a loading stand 11 to be loaded with a work 30 including a projecting alignment mark 40; a rotating tool 12 for cutting the work 30 loaded on the loading stand 11; a tool holding part 13 for holding the rotating tool 12; and a detector 14 for detecting external forms of the alignment mark 40 and the rotating tool 12. The detector 14 detects the external forms of the alignment mark 40 and the rotating tool 12 from at least two directions on sides of the work 30. Positioning of the alignment mark 40 and the rotating tool 12 is performed based on a result of the detection from the detector 14.
