Air bending is a forming process by which very complicated three-dimensional parts can be produced. A bending operation is performed on a station, consisting of a punch and a die. A part is produced by performing a sequence of bending operations, often requiring different stations. The stations that are necessary to produce the part are mounted on a press brake.
This paper discusses several approaches for the optimal placement of the stations on a press brake. Process constraints and objectives regarding efficiency are taken into account. Both exhaustive enumeration and neighbourhood search are used for solving the formulated problems. The reported computational experiments show that all problems can be solved satisfactorily.
