Method of adaptive planning of cutting patterns on base material surface is that geometric parameters of elements to be disposed on base material surface are identified, set of heuristics which provide elements' arrangements on base material surface are configured, preliminary cutting patterns are generated by configured arrangement heuristics. Next, optimization of achieved cutting patterns is performed with the use of meta-heuristic method which provides set of modified solutions. Each solution obtained by meta-heuristic is permutation of disposal sequence of cutting patterns generated by arrangement heuristics. Subsequently, at least set of the best arrangement heuristics according to preliminary patterns are performed taking into account sequence determined by meta-heuristic. Meta- heuristic and arrangement heuristics are performed alternately in manner described above till final condition is met, which can be time limit for computation, satisfying number of elements within pattern or state in which no improvement is achieved in particular number of successive iterations. Next, for the best obtained pattern sequence of cutting successive elements is determined what is done under certain constraints imposed by material parameters, cutting technology and optimization criteria like unit cutting cost. According to results of the last step machine code is generated and uploaded to cutting device. |
