| In order to solve the inefficiency and time consuming problems in traditional sheet metal production process,
the sheet metal unfolding and layout optimization application system was proposed based on CAD automation. The whole
process of structural system was designed. With the help of the relevant algorithm based on rotating the lowest horizontal
line. the smallest rectangle envelope method and the translational inarch algorithm. the problems of layout optimization
of rectangle and irregular rectangle were managed respectively. The plug-in system of automatic unfolding and layout
optimization of sheet metal based on AutoCAD. The system was mainly composed of parametric drawing, three-
dimensional map display, determination of the map and dimensional accuracy and other functional components. Finally,
through the example application. the system can effectively improve the production efficiency and manufacturing
precision, and reduce material wastage rate. |
