Layout, Bridge and Material Utilization
排样与搭边利用率优化
标签：排样, 搭边, 利用率, 废料
排样决定材料利用率。单排直排最简单但废料多；交错排（60°–90°斜排）可提效 5%–15%；对于对称小件用对排（一落两件）。搭边值取料厚的 1.5–2 倍且不小于 0.8 mm，过小会切边毛糙、过大则浪费。用 CAD 嵌套模拟后再开模。
Layout drives material utilization. Straight single-row nesting is simple but wasteful; staggered (60°–90° skew) nesting improves yield 5%–15%; for symmetric small parts use paired nesting (two blanks per hit). Set the bridge to 1.5–2× thickness but never under 0.8 mm—too small gives ragged edges, too large wastes stock. Simulate nesting in CAD before cutting the die. ---
