METHOD TO OPTIMIZE THE NESTING OF TWO BLANKS WITHIN A LONGITUDINALLY EXTENDING FLAT STRIP
It is a first purpose of the current invention to provide a computerized method to determine the best nesting of blanks in a strip in order to optimize the material usage and to determine the associated material usage. Solving the problem of material usage optimization involves at least three different variables (two rotation angles of the blanks and one transversal offset) and thus potentially involves optimizing the material usage function over a very large set of combinations. This leads to high computation times, which can be a serious hindrance to the implementation of the material usage optimization method. A second purpose of the current invention is therefore to provide a computerized method to accelerate the computerized determination of the best blank nesting for material usage optimization and the associated material usage.
