CNC + Hand Engraving Hybrid Workflow
CNC 雕刻机与手工雕刻混合流程
标签：CNC雕刻, 混合流程, 深雕, 手工刀痕
CNC 先以 V 刀（30°/60°）按矢量路径雕出全部主线条（深 0.2–0.6 mm），手工再以平口刻刀修出刀痕起线与肌理变化——纯 CNC 雕刻的「机刻味」来自刀路完全一致，混合流程保留 20–30% 手工重刀区。参数：黄铜 V 刀转速 24000 rpm、进给 300–600 mm/min；手工修区提前在 CAM 里指定边界，避免误修关键线。适合印章、铭牌等文字密集件。
CNC first cuts all primary lines with V-bits (30°/60°, 0.2–0.6 mm deep), then hand gravers re-cut 20–30% of the area for tool-mark variation—pure CNC looks mechanical because every pass is identical. Brass settings: 24,000 rpm, 300–600 mm/min feed; define hand-zones in CAM so gravers never stray onto critical lines. Ideal for seals, plaques and text-heavy work. ---
