CNC Spinning: Toolpath Programming Basics
CNC 数控旋压：路径编程基础
标签：数控旋压, CNC, 路径编程, 道次规划, 进给率, 批量生产
数控旋压用 G 代码或专用旋压 CAM 生成道次路径。紫铜 3 mm 板推荐：每道次壁厚减薄 ≤15%，滚轮进给 0.3–0.6 mm/r，道次间隙重叠 30–40% 防止起棱。首道次用偏置角度 25–30° 的拉深轮预成形，末道次用成形轮贴模。相对手工旋压，批量一致性可达 ±0.1 mm 壁厚，适合 50 件以上的订单。
CNC spinning generates passes from G-code or dedicated spinning CAM. For 3 mm copper sheet keep each pass under 15% wall reduction, roller feed 0.3–0.6 mm/r, and overlap consecutive passes 30–40% to avoid ridges. Open with a 25–30° profiling roller, finish with a planishing roller against the mandrel. Wall thickness repeatability reaches ±0.1 mm — worthwhile for orders of 50+ pieces. ---
