| Abstract: | This paper deals with the problem of generating optimal constrained cutting patterns for punch strips of a single type. The normal structure of the optimal layout is described. A branch and bound approach is used to find the optimal unconstrained layout. The optimal constrained layout is obtained through the solutions to a number of constrained layouts. We use the property of the optimal layout to facilitate the solution process. The computational results show that the algorithm is extremely efficient. The optimal solution to an example is given. |
