+# 整数型材下料方案
+
+| 位置 | 型材 | 每根长度 | 数量 |
+| --- | --- | --- | --- |
+| 底部纵梁 | 3030 | 255 mm | 2 |
+| 两个轴承板下方的横梁 | 3030 | 71 mm | 2 |
+| 电机两侧固定型材 | 2020 | 110 mm | 2 |
+| 灯光开关下方的横梁 | 2020 | 132 mm | 1 |
+
+两根轴承横梁与原版相比两端等量缩短，底部纵梁、电机、开关横梁及轴承板位置保留。轴承横梁两端与纵梁之间形成约 0.12 mm 的名义单侧装配间隙，由原有角码连接，不能把其理解为直接抵紧。四只角码的竖脚与纵梁、横脚与轴承横梁仍面接触；轴承板用的长孔角码也仍与横梁接触。空间比较和尺寸见 `validation.json`。
+
+总装 `Assembly.FCStd`、`Assembly.step` 已重新打开验证。上述下料长度为整数；角码、实际型材槽和滑块、灯光开关外形仍以简化或包络示意，尺寸和接触检查不是实物装配或结构承载试验。实际锯切公差应与加工方约定，确保两根横梁能装入纵梁之间；装配时利用角码长槽调整，不应强行夹紧拉弯。
