摘要
针对二维不规则图形零件在排样区域上的最优排列问题,将排样和制造工艺联系起来,先将多边形各边向外扩充,为零件预留加工余量;然后采用遗传模拟退火算法与小生境技术相结合,寻找排样件在排样时的最优次序及各自的旋转角度,再用基于"最低水平线与填充算法相结合"策略的启发式排样算法实现二维不规则件自动排样,得到了满意的优化排样结果。
To solve the two-dimensional irregular parts packing problem,firstly the problem is associated with manufacturing process,every side of polygons is expanded in consideration of the machining allowance.Then genetic simulated annealing algorithm and niche are integrated to find out the best sequence of the irregular parts and each part s optimum rotating angle,finally the lowest horizontal algorithm and filling algorithm are combined to complete the automatic layout.The satisfactory results of optimal layout have been obtained.
