Nesting-Algorithmus für irreguläre einfache Formen auf ebenen Flächenstücken

The leather processing industry requires considerable amounts of leather. The desire from an economic perspective is, that the leather waste is small. In small and medium-sized companies, optimizations are done from people by hand. The people try to place cutting parts on a leather skin, that the total of leather waste is small and they are arriving this with their experience. Larger leather processing companies are using computer-based optimization methods / algorithms (nesting algorithms) for leather cutting and cnc machines for optimization the cutting prozess. With this work, a new nesting algorithm for leather cutting optimization will be shown. The nesting algorithm is inspired by Human thought and action. The calculation and consideration of C-obstacle polygons have is an elementary component. By using enhanced methods for calculating polygon-union and polygon-difference it can be shown, that templates can be placed optimized on C-obstacle polygons with zero surfaces. Through a comprehensive analysis on the templates forms, the relative (the design) and absolute template size is shown, also that the approach and the evaluation of templates a fundamental part in nesting algorithms is
