冲压件的生产大多是大批量的,因此,优化冲裁件在条料上的排样,以最大限度地减少废料,对提高材料利用率,降低冲压件的制造成本以及减少繁琐的人工排样劳动具有重大的意义。冲裁件的排样方法通常有单排和双排(包括对头单排和对头双排)两大类,如图1所示。用传统的人工排样方法,往往费时多、效率低,用计算机辅助冲裁件的排样,则由于其具有高速运算的能力和准确、强大的逻辑判断能力,能在短时间内对各种排样方案进行比较,从中选出优化的排样方案。但对某些形状比较复杂的冲裁件,若用单排或双排样法进行 Stampings are mostly produced in large quantities, therefore, the layout of the blanking pieces on the strip is optimized to minimize scrap, which improves the material utilization, reduces the manufacturing cost of stamping parts and reduces cumbersome manual layout Labor is of great significance. Blanking pieces of the layout method is usually single row and double row (including the head row and head double row) two broad categories, shown in Figure 1. With the traditional manual nesting method, it is often time-consuming and inefficient, with computer-aided blanking pieces of the layout, because of its high-speed computing capabilities and accurate, powerful logical judgment, in a short period of time on a variety of Layout program to compare, select the optimal layout program. However, some of the more complex shapes of blanking pieces, if single row or double row method
