标签：课程设计, 体验课, 教学大纲, 锤痕控制
2 小时打平体验课：0–15 min 安全与噪声防护、握锤与站姿演示；15–45 min 在 1.5 mm 铜片上练 60% 重叠的直线走锤；45–75 min 上曲面砧收整一只 φ100 mm 小碟；75–100 min 自由练习并处理翘曲；最后 20 min 做旧抛光带走成品。进阶作业序列三级：①平面作业定厚公差 ±0.05 mm；②碗类作业四点壁差 ≤0.1 mm；③自选肌理的综合器皿。每级作业附退火次数与减薄记录表，教师据此判断升阶与补课内容。
A 2-h planishing taster: 0–15 min safety, hearing protection, grip and stance demo; 15–45 min straight-line hammering at 60% overlap on 1.5 mm copper; 45–75 min closing a φ100 mm dish over a curved stake; 75–100 min free practice with warp correction; final 20 min patina and take-home. The advanced sequence has three levels: a flat exercise at ±0.05 mm thickness tolerance; a bowl held to ≤0.1 mm wall variation at four points; then a free-textured vessel. Each level logs anneal counts and thinning so the instructor can judge progression and remedial work.
