3D Scan Verification of Formed Profiles
3D 扫描比对与成形精度校验
标签：3D扫描, 逆向校验, 成形精度, 数字化
手持激光扫描仪（精度 ±0.05 mm）扫描起凸中的坯件并与设计曲面比对，生成色差图指导下一轮锤击区域：红色区欠成形、蓝色区过薄。大件每完成 2–3 道次扫描一次，可提前发现壁厚超差区域并及时退火补敲。比对前需做公共点定位（磁力定位点 6–8 个）；扫描数据同时留档，用于修复或复制时重建原始曲面。
Handheld laser scans (±0.05 mm) of work-in-progress raised forms are compared to the design surface to produce deviation maps that guide the next hammering zone: red = under-formed, blue = over-thinned. Scan every 2–3 passes on large work to catch thickness drift early and anneal/correct in time. Register scans with 6–8 magnetic targets; archive the mesh for future repair or replication. ---
